Sea buckthorn (Hippophae rhamnoides L.) is in the focus of interest mainly for its positive
effects on health of both human and animal organisms. The whole plant of sea buckthorn and
especially its berries are a source of a large number of different bioactive compounds. The
greatest attention has been drawn to its high content of vitamins, minerals, natural antioxidants,
n-3 and n-6 fatty acids, and proteins. Sea buckthorn is valued for its antioxidant, cardioprotective,
antiatherogenic, antidiabetic, hepatoprotective, anti-carcinogenic, immunomodulatory, antiviral,
antibacterial, anti-inammatory and vasorelaxant effects. Due to these and other positive effects,
the plant is included in both human and animal nutrition, in the latter case to increase the
biological value of animal products. This review summarises the botanical characteristics of sea
buckthorn, lists the bio-active substances contained in individual parts of the plant, their effects
in the prevention of a number of different diseases and their possible utilisation in human and
animal nutrition.
Bioactive substances, therapeutic effects, functional food, nutrients
For humankind, vegetation is a source of basic nutrients, raw materials for industrial
use as well as many bioactive substances. Plants with exceptional properties and a wide
range of application include, beside others, the sea buckthorn (Hippophae rhamnoides
L.). Its Latin name is derived from the words “hippo”, meaning horse, and “phaos”, which
is gloss or are (Michel et al. 2012). Thus the compound may be translated as a shining
horse (Li and Beverid ge 2003), or more freely as a glossy coat (Val íček and Havelk a
Botanical characteristics
Sea buckthorn (Hippophae rhamnoides L.) is included in the Elaeagnaceae family
ezníček and Plšek 2008). It is a family of eudicots of the Rosales order. The family
includes around 100 species in three genera mostly found in the moderate geographical
latitudes of the Northern hemisphere. Seaberries are classied in the plant taxonomy into
six species and 12 subspecies (Bal et al. 2011). Sea buckthorn is native to Central Asia
ez níček and P ek 2008) and North-Western Europe. At present, it is also grown in
Canada and the USA (Yang and Ka llio 2001). Seaberries grown in the Czech Republic
mainly include sea buckthorn and Russian silverberry.
Seaberries are shrubs or small trees mostly no more than 3 to 4 m high (Michel et al.
2012). They are trees with alternate, often silver-gray, simple leaves and blossom without
crown. Seaberry branches are often covered with numerous rigid thorns (Řezníček and
Plšek 2008). Seaberries are dioecious and anemophilous. Male plants have ower buds ×
2–3 bigger than female plants. Flowers do not produce nectar and therefore, pollination by
insects is not possible; the only possibility is wind pollination (Li and Beveridge 2003).

Sea buckthorn has narrow lanceolate alternate leaves (Řezníček and Plšek 2008;
Michel et al. 2012). The top of the leaf is dark green. The bottom of the leaf is green with
silver-gray tone. The silver-gray colouring is caused by the presence of trichomes that are
only found on the bottom of leaves (Li and Beveridge 2003).
Seaberries naturally grow in higher altitudes at about 2000 to 3600 metres above sea
level. They are highly resistant to temperature extremes, well tolerating temperatures in
the range of –45 to +43 °C. They typically grow on riverbanks and on the sunny side of
steep slopes (Dhyani et al. 2007). Seaberries well tolerate drought, high levels of soil
salinity, and acid soils (Khan et al. 2010). Their root system is well organised. The roots
bear bulbils of dove egg size containing bacteria binding nitrogen in soil (Valíček and
Havelka 2008), as well as other essential components (Li and Beveridge 2003). The
roots are strong and that is why seaberries are often used to protect the soil against erosion
or in recultivation processes (Kumar and Sagar 2007).
Berries as well as other parts of sea buckthorn represent a rich source of biologically
active compounds. For this reason the plant has been in the centre of attention virtually
world-wide. The chemical and nutritional composition of sea buckhorn berries as well as
the content of bioactive compounds depend on many factors. The most important factors
include different subspecies, origin, climate conditions, time of harvesting, and methods of
processing (Bal et al. 2011).
Berries and seed of sea buckthorn
The numerous fruits are dark yellow, orange or red when ripe, oval shaped and 6–9 mm
long. The fruit consists of a seed wrapped in soft, juicy and eshy tissue – the pulp. The
seed is 2.8 to 4.2 mm long, dark brown, ellipse-shaped and glossy on the surface (Michel
et al. 2012).
The chemical composition of berries depends on the variety, climate conditions, fruit
size, ripeness and the processing method (Leskinen et al. 2010). Sea buckthorn and
especially its berries provide a rich source of many minerals, including, but not limited to
Ca, P, Fe, and K. Sea buckthorn has a large content of vitamin C, several-fold compared
to other fruits (Christaki 2012). The vitamin C content in sea buckthorn ranges between
360 and 2500 mg/100 g (Bal et al. 2011). The plant is a valuable source of the vitamin B
group, mainly B1 (thiamine) and B2 (riboavin) (Christaki 2012). Other vitamins rich
in sea buckthorn include, for example, vitamin E (Michel et al. 2012), vitamins A and K
(Bekker and Glushenkova 2001; Fatima et al. 2012). The berries provide a good source
of carotenoids, mainly ß-caroten, lycopene, lutein, and zeaxantin (Michel et al. 2012). The
saccharide content is also high. The most common carbohydrates are glucose, fructose,
and xylose. All parts of the plant contain many different proteins, mainly albumins and
globulins (Li and Beveridge 2003). Sea buckthorn is a source of organic acids, mainly
malic acid, quinic acid, oxalic acid, citric acid, and tartaric acid. Sea buckthorn is a good
source of avonoids too, mainly quercetin, kaempferol, myricetin, and isorhamnetin, and
an important source of tocopherols (Fatima et al. 2012).
The pulp
The pulp of sea buckthorn contains mainly α-, ß- and γ-carotens, glycopene, and zeaxantin.
Vitamin B group is mainly represented by B1 (thiamine), B2 (riboavin), B6 (pyridoxine),
vitamin PP (nicotinamine, niacin, vitamin B3), and folic acid necessary for nucleic acid
synthesis. The vitamin C content depends on the variety and natural conditions. Plants
growing in Central Asia contain 150–200 mg/100 g, and Alpine plants contain around
800 mg/100 g. The berries do not contain ascorbinase for ascorbic acidolysis, thus vitamin
C is well preserved in dry fruit and in products (Valíček and Havelka 2008). The peel of
the stem and fruits contains 5-hydroxytryptamine, which is found rarely in plants (Kumar
et al. 2011). This substance (5-hydroxytryptamine) is used for treatment of post-shock
Sea buckthorn leaves
The leaves contain a remarkable quantity of nutrients and bioactive substances, mainly
phenolic. They contain on average 3.8% of saccharides, 0.2% of protopectin, 1% of
organic acids, 170 mg/100 g of catechin, polyphenols, carotenoid lycopene, bioavonoids,
and coumarins. The leaves also contain a signicant concentration of vitamin C (up to
370 mg/100 g) and tannins (8%) (Valíček and Havelka 2008).
Sea buckthorn oils
Two oil types may be extracted from the sea buckthorn, either from the pulp or from the
seeds. The pulp contains 4–13% of oil, and dry pulp contains about 20–25% of oil (Zeb
2006; Valíček and Havelka 2008). Sea buckthorn is a good source of mainly unsaturated
fatty acids (Christaki 2012). The pulp oil contains 180–240 mg of carotenoids in 100 g,
of them 40–100 mg in form of caroten, 110–330 mg of vitamin E and unsaturated fatty
acids, mainly linoleic and linolenic acids. Specic types of acids include ursolic acid and
oleanolic acid, with anti-inammatory, wound healing, toning and blood pressure reducing
effects (Valíček and Havelka 2008). The pulp oil contains the highest concentration of
palmitoleic acid (16:1, n-7), up to 43% (Fatima et al. 2012).
Sea buckthorn seeds contain 8–20% oil (Kumar et al. 2011). The oil content is mainly
affected by the harvest time, size, and colour of berries (Yang and Kallio 2002). Seed
oil mainly includes unsaturated fatty acids – 90% (linoleic 47 mg, linolenic 18 mg, oleic
16 mg) and saturated palmitic acid (Valíček and Havelka 2008). Seed oil is the only oil
with the linoleic acid to linolenic acid ratio of 1:1 (Yang and Kallio 2002; Cenkowski
et al. 2006; Kumar et al. 2011).
Oil pressed from sea buckthorn seeds is mainly rich in essential fatty acids such as
linoleic acid (18:2, n-6), making up to 42% of the total fatty acid, and α-linolenic acid
(18:3, n-3), up to nearly 39% of the total fatty acid content. Sea buckthorn is also a good
source of oleic acid (18:1) (Christaki 2012). In addition to the above, the oil also contains
other n-3 and n-6 as well as n-7 and n-9 fatty acids, which are present in lower quantities
(Solcan et al. 2013).
Selected major effects on health of organisms
The sea buckthorn berries have been used for centuries by inhabitants of Europe, Central
and South-Eastern Asia in traditional medicine for treatment of different diseases as well as
for disease prevention (Li and Beveridge 2003; Michel et al. 2012). In China sea berries
have been used in traditional medicine for centuries (Li and Beveridge 2003).
At present, sea buckthorn has become popular especially for its positive effects on
the human organism. Sea buckthorn is valued for its antioxidant, cardioprotective,
antiatherogenic, antidiabetic, hepatoprotective, anti-carcinogenic, immunomodulating,
antiviral, antibacterial, anti-inammatory and vasodilating effects (Table 1). It also reduces
occurrence of stomach ulcers, supports wound healing, accelerates treatment of skin
disorders and reduces pain (Suryakumar and Gupta 2011; Christaki 2012; Michel et
al. 2012). Other important properties of sea buckthorn include its cytoprotective effects.
Sea buckthorn acts positively against asthma and pulmonary diseases (Upadhyay et al.
2010), against increased sebum secretion and affects platelet aggregation (Khan et al.
2010). Its antistress and adaptogenic activities have been conrmed (Michel et al. 2012).
Sea buckthorn also positively affects metabolic diseases (Bal et al. 2011), with the
ability to slow down ageing and protect against radiation-induced damage, accelerate the
healing of burns and frostbites, and reduce hair loss. Sea buckthorn also positively affects
mental functions, in particular reducing memory loss in elderly people. Its positive effects
have been utilised for acceleration of wound healing, especially in people after ear, nose
and throat operations where seaberry oil has been part of the treatment. The oil has also
been used for protection against solar radiation (Li and Beveridge 2003). Sea berry
products may be used in various drug forms from liquids via powder, patches, pastes, lms,
ointments and aerosols to suppositories (Li and Beveridge 2003).
Antioxidant effects and immunomodulating properties
Sea buckthorn contains many natural antioxidants in all of its parts. Its leaves, stems,
tubers, roots as well as blossom contain a high content of ascorbic acid (vitamin C), and
also carotenoids, polyphenols, avonoids, tocopherols, alkaloids, chlorophyll derivates,
amino acids and amines (Bal et al. 2011; Christaki 2012). Other natural antioxidants

Increased utilisation of vitamin A
present in sea buckthorn include sterols, tannins, vitamins, and minerals (Kumar et al.
Natural antioxidants inhibit or delay the oxidation of other molecules by inhibiting the
initiation or propagation of oxidizing chain reactions (Bal et al. 2011). Free radicals,
a product of cellular metabolism, can cause a number of diseases by exogenous chemical
or stress effects (cancer, diabetes mellitus, cardiovascular and nerve system disorders)
(Upadhyay et al. 2010; Kumar et al. 2013). Kim et al. (2011) evaluated the antioxidant and
alpha-glycosidase inhibitory effects from the extract, fractions, and isolated compounds of
sea buckthorn leaves The butanol fraction, which contained the highest amount of phenolic
compounds, showed higher radical-scavenging activity and also the most powerful alpha-
glycosidase inhibitory effect.
Flavonoids of sea buckthorn also provide antioxidant and anticarcinogenic effects. They
protect cells against oxidative damage, subsequent genetic mutations, and cancer (Gao et
al. 2000; Zeb 2006; Suryakumar and Gupta 2011). A potential chemopreventive effect
of sea buckthorn berries in mice was observed by Suryakumar and Gupta (2011). In
high-fat diet-induced obese mice sea buckthorn leaf tea proved their antioxidant effect and
effect of visceral obesity reduction (Lee et al. 2011).
Cardioprotective effects
Flavonoids contained in sea buckthorn as well as the unsaturated fatty acids contained
in sea berry oil are able to improve the function of the cardiovascular system (Zeb
2006; Suryakumar and Gupta 2011) and to prevent heart diseases (Christaki 2012).
Flavonoids show a favourable effect on the strength of heart muscle contraction and the
cardiac rhythm (Li and Beveridge 2003; Kumar et al. 2013). The effect of sea buckthorn
on cardiovascular functions and coronary microvessels in spontaneously hypertensive
stroke-prone rats was studied by Koyama et al. (2009). Experimental rats were fed
a feed enriched with sea buckthorn powder at the amount of 0.7 g/kg of feed for 60 days.
The effects included a signicant decrease of the mean arterial blood pressure, heart rate,
total plasma cholesterol, triglycerides and glycated haemoglobin in the rats. The arteriolar
capillary portions of microvessels expressing alkaline phosphatase decreased, but there was
a trend for an increase in the total capillary density. It was concluded that sea buckthorn
fruits improved the metabolic processes and reduced hypertensive stress on the ventricular
Another study focusing on the antihypertensive effect of total avonoids from sea
buckthorn seeds and mechanism of their action in long-term sucrose-fed rats by evaluating
its ability to regulate insulin and angiotensin II concentrations was done by Pang et al.
(2008). Feeding a high sucrose diet (HS: 77% kJ from carbohydrates, 16% from proteins,
6% from lipids) for 6 weeks resulted in a signicant increase of the systolic blood pressure
by 25.6%, plasmatic insulin concentrations by 114.24%, triglyceride contents by 82.14%,
and activated angiotensin II contents in the heart and the kidneys. Administration of a diet
enriched with sea buckthorn avonoids signicantly reduced the increased hypertension,
hyperinsulinaemia and dyslipidaemia. In addition, this diet (mainly at 150 mg/kg/day)
increased the blood concentration of circulating angiotensin II. The results showed that
the antihypertensive effect of the sea buckthorn enriched diet at least in part improved
insulin sensitivity and blocked the angiotensin II signal path. The study proved that a diet
with total avonoids extracted from sea buckthorn seed residues may be used for treatment
of hyperinsulinaemia in the non-diabetic state with cardiovascular diseases (Pang et al.
The most important avonoids are quercetin and isorhamnetin (Suryakumar and
Gupta 2011). The abovementioned effects are probably achieved by reduced blood glucose
concentrations, absorption of free radicals (Suomela et al. 2006), reduced susceptibility of
low-density lipoproteins to oxidation (Eccleston et al. 2002) and anti-hypertensive effect
(Wang et al. 2011).
Antiatherogenic effects
Sea buckthorn food supplementation has been proved to be able to reduce total cholesterol,
triglycerides and LDL-cholesterol, and increase HDL-cholesterol levels in comparison to
sea buckthorn-free diet (Yang and Kallio 2002; Suryakumar and Gupta 2011). Seed
oil is the most effective in this area (Christaki 2012). Basu et al. (2007) found that seed
oil of seaberries showed signicant antiatherogenic and cardioprotective effects in rabbits.
Antibacterial and antiviral effects
Antibiotic treatment of bacterial diseases is in many cases less effective and leaves
residues in animal products (e.g., bee products, etc.). It is therefore necessary to nd an
alternative, especially using natural ingredients (Kuzyšinová et al. 2014). The phenolic
compounds of sea buckthorn represent the main group of phytochemicals which exhibit
antibacterial and also antiviral effects. These compounds both suppress gram-negative
bacteria (Khan et al. 2010) and reduce gram-positive bacteria (Kumar and Sagar 2007).
A recent study involves a new phytochemical substance called hipporamin. It is a phenolic
compound from a nature source (Michel et al. 2012). Hipporamin positively suppresses
a wide spectrum of bacterial as well as viral diseases (Suryakumar and Gupta 2011).
Antimicrobial activities have also been reported for sea buckthorn berries (Puupponen-
Pimia et al. 2001), seeds (Chauhan et al. 2007) and leaves (Upadhyay et al. 2010).
Mic hel et al. (2012) report that the active agents contained in sea buckthorn manly inhibit
Bacillus cereus, Pseudomonas aeruginosa, Staphylococcus aureus, Yersinia enterocolitica
and Enterococus faecalis bacteria. These effects are mainly shown by extracts from sea
buckthorn leaves. Oil obtained by pressing is a very effective inhibitor of bacterial growth,
especially of Escherichia coli (Christaki 2012). Also Kaushal and Sharma (2011)
conrmed that sea buckthorn seed oil showed good antimicrobial properties (growth
inhibition zone diam. 4.0 mm) against Escherichia coli.
Sea buckthorn has also shown unique biological properties against viral diseases, anti-
viral activity against the inuenza virus and herpes virus. The suppressing effect on the
inuenza virus is provided by inhibition of viral neuraminidase present in the virus. Sea
buckthorn also positively inhibits HIV infections in cellular cultures (Shipu lina et al.
2005; Michel et al. 2012). J ain et al. (2008) suggest that the sea buckthorn leaf extract
has a signicant anti-Dengue activity and has a potential for the treatment of Dengue fever.
Anti-inammatory effects
In traditional medicine sea buckthorn has been used for treatment of stomach ulcers for its
effect on anti-inammatory mediators (Xing 2002). Oil and leaves support regeneration of
skin wounds and support treatment of skin disorders (Upadh yay et al. 2009). Palmitoleic
acid contained in sea buckthorn is a component of skin fat and thus represents a valuable
component of topical treatment of cellular tissue and wounds (Bal et al. 2011; Kumar et
al. 2011). Sea buckthorn leaves are able to protect irradiated mice against inammation
(Tiwari and Bala 2011). Li and Bever idge (2003) report that Russian cosmonauts used
sea buckthorn berries in their diet and oils in creams for protection against solar radiation.
Antidiabetic effects
Other positives of sea buckthorn include mitigation of the symptoms of diabetes mellitus.
This effect is caused by achieving reduced blood glucose concentrations by dietary
supplementation with sea buckthorn (Chr istak i 2012).
In diabetes, sea buckthorn not only affected the lowering of blood sugar including fasting
blood glucose and two h postprandial blood glucose, but also the treating of complications.
Sea buckthorn has been shown to be effective in cell cultures, animal studies, and clinical
practice. Although sea buckthorn has been shown to have positive effects in relieving
symptoms such as fatigue, dry mouth, and dry eye in non-diabetic diseases, it is still
unclear whether it has a therapeutic effect on the symptoms of diabetes. Studies have to be
conducted to test and verify the effect of sea buckthorn on symptoms in diabetic patients.
On the whole, sea buckthorn is a candidate for complementary therapy of diabetes (Wang
et al. 2011).
Anticarcinogenic activity
Favourable effects of sea buckthorn also include the anticarcinogenic activity (Mi chel
et al. 2012). Anticarcinogenic effects have mainly been reported for substances extracted
from sea buckthorn berries (Ch ristak i 2012). One of the main components contributing
to this effect is quercetin that induces apoptosis in cancer cells. The best effect has been
reported in relation to the treatment of patients with colon cancer, leukaemia, and prostatic
carcinoma (Pate l et al. 2012). Other studies suggest that sea buckthorn oil alleviates
haematological damage caused by chemotherapy, such as part of treatment of leukaemia
(Yan g and Kall io 2002). Therapeutic effects are ascribed to substances such as catechin,
gallocatechin, and epigallocatechin (Kha n et al. 2010). Sea buckthorn has also been
reported to favourably affect the inhibition of certain factors causing stomach cancer in
humans (Li and Bev eridge 2003).
Yasukawa et al. (2009) isolated and identied three phenolic compounds, (+)-catechin,
(+)-gallocatechin, and (-)-epigallocatechin and a tritepenoid, ursolic acid from the active
fraction of the 70% ethanol extract of sea buckthorn which exhibited a remarkable anti-
tumour activity.
Induction of the apoptotic activity and apoptotic morphological changes of the nucleus
including chromatin condensation were also observed in the HL-60 cells treated with some
of the avonols isolated from sea buckthorn such as quercetin, kaempherol, and myricetin
(Hibasami et al. 2005).
Hepatoprotective effects
The liver is often affected by a multitude of environmental pollutants and drugs, all
of which place a burden on this vital organ which can damage and weaken the liver and
eventually lead to hepatitis or cirrhosis (Zimmerman and Ishak 1994). Sea buckthorn has
shown numerous positive effects on liver protection and treatment of liver diseases (Barkat
et al. 2010). Hepatotoxins such as ethanol, carbon tetrachloride, and acetaminophen cause
various degrees of hepatocyte damage, degeneration, and subsequent death of hepatic cells
(Ramesbabu et al. 2011; Michel et al. 2012; Solcan et al. 2013). Substances contained
in sea buckthorn such as unsaturated fatty acids, α-tocopherol or ß-caroten protect hepatic
cells against damage by hepatotoxins (Ramesbabu et al. 2011). Flavonoids are mainly
responsible for protection against liver fattening (Li and Beveridge 2003). Sea buckthorn
might also contribute to prevention of liver brosis in the future (Suryakumar and Gupta
A trial focused on the effect of sea buckthorn on the toxicity of oxidized cholesterol
proved that sea buckthorn administered in the diet reduced plasma concentrations of alanine
transaminase (ALT), aspartate transaminase (AST), and alkalic phosphatase (ALP), which
indicates that the plant may have a protective effect against hepatotoxicity induced by
oxidized cholesterol (Yeh et al. 2012).
The hepatoprotective activity of sea buckthorn leaves and seed oil was evaluated using
carbon tetrachloride (CCl4) induced hepatic damage in animals (Geetha et al. 2008; Hsu
et al. 2009). The results showed that sea buckthorn leaf alcoholic extract as well as seed oil
ameliorated CCl4-induced liver injury as evidenced by both histological and biochemical
In a study by Maheshwari et al. (2011), some of the phenolic constituents of sea
buckthorn leaves, such as gallic acid, myricetin, quercetin, kaempferol, and isorhamnetin
were identied in the phenol rich fraction by reverse-phase high-performance liquid
chromatography (RP-HPLC). Oral administration of the phenol rich fraction at dose of
25–75 mg/kg body weight signicantly protected from CCl4 induced elevation in aspartate
aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase and bilirubin in
serum, enhancing hepatic antioxidants. These observations suggest that the phenol rich
fraction has a potent antioxidant activity and prevents against CCl4 induced oxidative
damage in the liver.
Immunomodulating effects
Sea buckthorn strengthens and accelerates the immune response of the organism (Mic hel
et al. 2012). It accelerates regeneration of mucous membranes in the gastrointestinal tract,
such as in the stomach, the large intestine, the urinary tract, and the oral cavity (Chr istaki
2012). The sea buckthorn components most contributing to the immunomodulating effect
include avonoids such as leucocyanidin and catechin in the rst place and then also
isorhamnetin, quercetin, and quassin. These substances strengthen the immune system of
the organism and increase resistance to illnesses (Li and Be verid g e 2003).
The immunoprotective effect of sea buckthorn fruit against immunodepression caused by
T-2 toxin was tested in broiler chicks (Ram asamy et al. 2010). The immunoprotective effect
of sea buckthorn and glucomanane was evaluated with the help of humoral immune reaction
against NCD (Newcastle disease virus), LaSota strain vaccine (haemoagglutination test),
immunoglobulin concentrations, phagocyte index and DTH (delayed-type hypersensitivity)
reaction against 2, 4-dinitrourobenzene (DNFB) between days 25 and 28 of the trial.
A signicant decrease of non-specic immunity was observed in the group receiving T-2
toxin, shown by the phagocyte index, DTH reaction, haemagglutination inhibition (HI)
titre and total serum Ig, in comparison with the healthy control group. The group fed sea
buckthorn and glucomanane showed a signicant increase of the HI titre and total serum
Ig. These birds also showed a signicant increase of the DTH reaction and non-specic
immune response. Sea buckthorn itself protected against the immunosuppressive effect
of T-2 toxin, but sea buckthorn in combination with glucomanane showed an additional
protective effect against T-2 toxicity.
According to Lav inia et al. (2009) essential oils extracted from sea buckthorn berries
improve the immune response in broilers. The skin of broiler chicks fed sea buckthorn
showed a higher degree of lymph-follicular reaction (Lonar e et al. 2009). Sea buckthorn
oil supports tissue regeneration, with consequent positive effects on mucous membranes
such as in the stomach (Erkko la and Yang 2003), the duodenum (La vinia et al. 2009),
the urogenital tract, and the oral cavity (Erk kola and Yang 2003).
Effects suppressing the occurrence of gastric and duodenal ulcers
Hexane extract from sea buckthorn acts positively against indomethacin, stress, and
ethanol which contribute to the development of gastric ulcers (Khan et al. 2010). The
extract also shows positive effects in the treatment of duodenal ulcers (Li and Beve ridge
Huff et al. (2012) studied the efcacy of a commercial product containing the berries
and pulp of sea buckthorn in the therapy and prevention of gastric ulcers in horses. The
mean score of non-glandular gastric ulcers signicantly (P < 0.05) increased in all the
horses after an intermittent feed deprivation. The number of glandular ulcers and their
severity were signicantly lower in horses fed sea buckthorn enriched feed compared to the
control group. Sea buckthorn was not effective in the therapy/prevention of natural equine
non-glandular ulcers, however, the glandular ulcer score was signicantly lower in the sea
buckthorn fed group after feed deprivation. Sea buckthorn may therefore be used in the
prevention of glandular ulcers in horses in case of intermittent feeding.
Dermatological effects
Substances contained in sea buckthorn prevent dermatological diseases such as atopic
eczema (Khan et al. 2010). Creams containing sea buckthorn extracts support treatment of
skin disorders such as melanosis, chloasma, xeroderma, and recurrent dermatitis (Li and
Bev eridg e 2003; Barka t et al. 2010).
Burnt sheep were administered sea buckthorn seed oil and in 6, 14 and 21 days after
the injury, the wound blood ow and epithelization were determined. After 14 days the
percentage of epithelization in the areas treated with sea buckthorn was higher than in the
untreated areas. The epithelization time was signicantly shorter compared to the untreated
areas (Ito et al. 2014).
Platelet aggregation
Positive effects on platelets are mainly shown by avonoids and fatty acids. Their main
function is suppression of platelet aggregation induced by collagen, probably by inhibition
of the thyrosine kinase activity (Patel et al. 2012). Another substance signicantly
contributing to platelet aggregation is sitosterol (Joh ansso n et al. 2000).
Thanks to the abovementioned favourable effects on the health of organisms, in the
future sea buckthorn and its products may be expected to be widely used in therapy and
prevention both in humans and animals.
Role of sea buckthorn in human and animal nutrition
Interest in utilisation of sea buckthorn products has been increasing recently in the area
of human as well as animal nutrition. Thanks to the functional properties and unique taste
of the berries they can be used for production of juice, bonbons, jelly, jam, alcoholic and
non-alcoholic beverages or dairy product avours (Gao et al. 2000; Bal et al. 2011). Oils
from the seeds and pulp may be used as ingredients in food supplements such as jelly, plant
capsules, or oral uids (Yan g and Kalil o 2002). They are also used in cosmetic products
such as shampoo (B a l et al. 2011). Leaves are used for production of extracts, teas or
cosmetics (Gua n et al. 2005).
Sto bdan et al. (2013) report that sea buckthorn is a rich source of nutrients and bioactive
substances. Juice made from the berries is rich in sugar, organic acids, amino acids,
essential fatty acids, phytosterol, avonoids, vitamins, and minerals. The juice contains
24 minerals and 18 different amino acids. Total phytosterol content is × 4–20 higher than
in soybean oil. Seeds represent a valuable source of oil with high level of oleic acid and the
1 : 1 ratio of n-3 and n-6 fatty acids. The oil absorbs ultraviolet light and promotes healthy
skin. The leaves contain many nutrients and bioactive substances such as carotenoids, free
and esteried sterols, triterpenols, and isoprenols.
Sea buckthorn has long been used in animal nutrition as an additive to feed mixtures
for its favourable effects on animal health. A positive effect on the quality of farm animal
products has been observed. Ancient Greeks used leaves and twigs of sea buckthorn for
feeding animals, with a positive effect on the weight gain and shinning coat, especially in
horses (Sur yakum ar and Gupt a 2011).
Kau shal and Sharm a (2011) report that seed cakes and sea buckthorn leaves
are rich in proteins and minerals and represent a benecial animal feed. Similarly
Bis was et al. (2010) consider sea buckthorn leaves, seed and berry residues a suitable
feed for farm animals and poultry, mainly in dry and cold regions. In poultry, sea
buckthorn positively affected the egg production and body weight of laying hens
(Wang 1997).
Although information about potential applications of sea buckthorn and its products in
animal nutrition and its potential positive impact on animal product quality is available,
further research studies and knowledge in this area may signicantly contribute to the
extension of the sea buckthorn application area.
The study was supported by the Internal Grant Agency of the University of Veterinary and Pharmaceutical
Sciences in Brno IGA 1/2014/FVHE.

Sea buckthorn (Hippophae rhamnoides L.), belonging to the oleaster family, has been used for long time in Asian folk medicine. Even today we can see increasing interest in that plant because of its variety of biologically active compounds, which are contained in its fruits, leaves and seeds. These chemical compounds determine versatile applications of sea buckthorn in various fields of human life. Due to its regenerative properties, sea buckthorn is used as a component of numerous dermocosmetics, protecting the skin from UV radiation, dryness and some diseases or signs of aging. Active substances, such as poliphenols, contained in sea buckthorn have significant properties: antimicrobial, antiviral, antifungal and anti-inflammatory. Therefore that plant is widely applied in pharmacy to produce drugs, juices, extracts and oils. These forms of products found usage in the treatment of many disease such as: cancer, liver cirrhosis, diabetes, heart disorders etc. Sea buckthorn is widely used in the food industry as well-variety of beverages and jams are made from this plant. H. rhamnoides can be also used as a preservative or food additive, which increases the organoleptic and nutritional properties of food. Beside of that, sea buckthorn is useful in animal nourishment. Feed enriched with H. rhamnoides has a positive impact on the nutrition and health of the animals, while improving their productivity. The aim of that article was to present the variety of compounds which are responsible for that plant's properties.

Sea buckthorn is becoming an increasingly popular medicinal plant. This plant material contains many nutrients and bioactive substances used in the food, cosmetic, and pharmaceutical industries. Compounds found in the organs of this plant have antiviral, antibacterial, and antifungal properties, but, despite these features, sea buckthorn is affected by many pathogens. As shown by studies on the health and presence of pathogenic fungi on the aboveground organs of this plant, no obligatory pathogens and Basidiomycota fungi were found in 2019. The mycological analysis of the aboveground organs, i.e. leaves, fruits, and shoots, showed that Alternaria alternata was the most frequent species of fungi isolated from all examined organs. Moreover, the Monilinia fructigena and Botrytis cinerea species were often isolated from fruits and Cladosporium cladosporioides fungus was found on leaves. Numerous isolates of the pathogenic Fusarium sporotrichiodes fungus and single isolates of Phomopsis spp., i.e. fungi causing gangrene and drying out of the bark of shoots and the bark of many fruit plant species, and Nigrospora oryzae causing leaf blotch of herbaceous plants and fruit trees were obtained from the examined organs of the sea buckthorn. The mycological analysis revealed no species of the genus Verticillium , universally recognized as the most dangerous to this plant.
... Hippophae rhamnodies L. (H. rhamnodies), named Sea Buckthorn, is included in the Elaeagnaceae family and is good known for its antioxidant, antidiabetic antiviral, antibacterial, anti-inflammatory, cardioprotective, vasodilating, hepatoprotective, antiatherogenic, anticarcinogenic, immunomodulating and hypocholesterolaemic effects [9,10]. Sea buckthorn essential oil (SBEO) is an important source of mainly unsaturated fatty acids (mainly linoleic and linolenic acids) and presents important inhibitory potency against human liver cancer cells, human acute myeloid leukaemia, prostate cancer and glioma cells [11,12]. ...
... Some studies have confirmed that consumption of sea buckthorn fruit flavonoids can reduce blood TG and TC levels (18). In the current study, addition of 1.5 g/kg SBE, reduced serum LDL-C levels, which is consistent with the results of Krejcarová et al. (33) and Ma et al. (34), confirming the ability of SBE to reduce lipids. This indicates that the addition of SBE to the diet can reduce cholesterol deposition in Egg. ...

The purpose of this experiment was to study the effect of sea buckthorn extract (SBE) supplementation on the production performance, serum biochemical indexes, egg quality, and cholesterol deposition of laying ducks. A total of 240 23-week-old laying ducks (female ducks) with similar body weight were randomly divided into four treatment groups with 6 replicates of 10 each. The experimental groups were fed diets supplemented with 0, 0.5, 1.0, and 1.5 g/kg of SBE, respectively. The results showed that the addition of 1.0 g/kg SBE to the diet had significant increase (P < 0.05) in average egg weight and feed conversion ratio. The inclusion of SBE showed the significant improvement (P < 0.05) in yolk weight, shell strength, egg white height and haugh unit. Ducks fed with 1.0 and 1.5 g/kg SBE displayed a significant decrease (P < 0.05) in yolk cholesterol. The significant improvements were observed in the contents of total amino acid essential amino acids, non-essential amino acids, umami amino acids, monounsaturated fatty acids, and docosahexenoic acids of eggs (P < 0.05) when supplemented with SBE. However, the contents of total saturated fatty acids, polyunsaturated fatty acids, n-3 polyunsaturated fatty acids and n-6 polyunsaturated fatty acids in eggs showed decrease when ducks fed with SBE diets (P < 0.05). SBE diets may reduce (P < 0.05) the levels of serum total cholesterol, triglyceride, and low-density lipoprotein cholesterol, while increased (P < 0.05) the levels of serum superoxide dismutase, total antioxidant capacity, and glutathione catalase compared to the control. The levels of serum immunoglobulin G, immunoglobulin A and immunoglobulin M were improved in SBE diets (P < 0.05) in comparation to the control. The addition of SBE to diets can improve feed nutrient utilization, increase egg weight, optimaze egg quality and amino acid content in eggs, reduce blood lipids, improve fatty acid profile and yolk cholesterol in eggs, and increase antioxidant capacity and immunity in laying ducks.

Unlike in animals, dioecy among flowering plants is a rare phenomenon. The vast majority of angiosperm species have a bisexual flower that combines male (androecium) and female (gynoecium) reproductive organs. However, about a quarter of species have dioecious flowers, which can be located within the same plant (monoecious) or on different plants (dioecious). The flower formation in dioecious plants is determined by various genetic mechanisms. They become more complex from the work of a single gene to the functioning of full-fledged heteromorphic sex chromosomes, which can directly affect sex differentiation or participate in the balance determination of sex (where the formation of male or female flower organs depends on the ratio of X chromosomes to autosomes, for example). In recent years, the development of sequencing techniques, bioinformatics, and molecular biology has led to an increase in interest in the sex determination mechanisms among plants. It is noteworthy that a significant number of dioecious plants have economic value. At the same time, dioeciousness often complicates the growing process. This fact increases the relevance of studies on dioecious crops. In this review, we attempt to summarize the current information on sex chromosomes and the mechanisms of sex determination in dioecious plants, concentrating on species with agricultural importance.
... In this experiment, 40 birds that were supplemented sea buckthorn seeds had decreased level of egg cholesterol [28]. Krejcarová et al. [29] also noticed that supplementation of sea buckthorn seeds reduces serum cholesterol concentration [29]. ...

Sea buckthorn (Hippophae rhamnoides L.) is a small tree, valued for its medicinal properties throughout the ages. Sea buckthorn berries and leaves are a known source of phytochemicals and have been used in the treatment of inflammation, oedema, hypertension, ulcers, and wounds in folk medicine. Sea buckthorn seeds are natural dietary sources of various bioactive compounds as well, but the number of studies on their content and biological properties is still insufficient. For the first time, we examined the phytochemical content and biological activity of sea buckthorn seeds in vitro. We have studied the effect of two extracts—from regular (no thermal processing) and roasted (thermally processed) sea buckthorn seeds—on the levels of oxidative stress induced by H2O2/Fe2+ in plasma, coagulation times, and white thrombus formation (measured by Total Thrombus-formation Analysis System—T-TAS). We observed that sea buckthorn seeds contain diverse flavonoids, mostly glycosides of isorhamnetin, kaempferol, and quercetin, as well as smaller amounts of proanthocyanidins and catechin, triterpenoid saponins, and a number of unidentified polar and hydrophobic compounds. Both extracts inhibited lipid peroxidation and protein carbonylation, but only the extract from roasted seeds decreased oxidation of thiol groups in plasma treated with H2O2/Fe2+. They did not alter coagulation times, but the extract from roasted seeds at the highest concentration (50 µg/mL) prolonged the time needed for white thrombus formation. The results indicate that sea buckthorn seeds have antioxidant activity that is not impaired by thermal processing and possess anticoagulant potential, but more research is needed in order to ascertain which compounds are responsible for these effects, especially in in vivo models.
BACKGROUND: Sea buckthorn (SBT) (Hippophae rhamnoides L.), a shrub rich with a huge variety of vitamins, antioxidants and other biologically active constituents with pharmacological and cosmaceutical applications. OBJECTIVE: The current review aims to compile the recent reported data on the ethnobotany, phytochemistry, biological activities and cosmaceutical uses of SBT plant from different regions of the world. METHODS: A wide-ranging inquiry on SBT was done electronically on the basis of articles and abstracts published in peer-reviewed journals, issued in conference proceedings, government reports, books, Master’s and Ph.D. theses etc. The research was carried out in different International scientific databases like Academic Search, Biological Abstracts, BIOSIS, BioOne Previews, CabDirect, Cochrane Library, Pubmed/Medline, GeoRef, Google Scholar, JSTOR, Journal Citation Reports, Mendeley, Publons, Researchgate, Scopus, SciELO, Springer Link, Science Direct, Web of Science, Taylor and Francis with particular keywords. RESULTS: A total of 185 published papers were assessed through the search approach and 162 papers were included published on SBT. It was evident from the literature search that the uses of SBT as traditional medicine so far against nearly 50 health related complications in more than 18 regions of the world are still a common practice where the decoction of leaves and juice/paste from berries/fruits of SBT were the common administration modes. Data on the phytochemical profile of SBT revealed more than 50 diverse reported groups of compounds with remarkable antioxidant activity against reactive oxygen species (ROS) using DPPH, FRAP and ABTS as common methods. Moreover to-date, the reported antimicrobial activity of SBT uncovered that the extracts from SBT were examined in contradiction of 32 strains of bacteria and 15 strains of fungus with significant inhibitory actions against the bacterial and fungal strains. The SBT extracts actions reported so far on different viral disease categories displayed active inhibition of the growth of nearly 15 different viral strains. The reported anticancer activity of compounds in SBT extracts to date evidenced remarkable results against more than 20 different cancer cell lines/ types. Moreover, SBT oil containing fatty acids, tocopherols and carotenoids is effectively used with cosmetics applications for skin care. CONCLUSIONS: Conclusively, SBT is rich with several remarkable phytochemicals that may have diverse biological actions and for that reason reassure the use of decoctions and/or infusions of SBT as folk traditional medicine around the world. Conversely, it is essential to explore the molecular mechanisms of compounds responsible for biological activites of SBT and to advance in the research of clinical uses and development of SBT based therapeutic and cosmetic products.
Degenerative nerve diseases are age-related, progressive and cause irreversible neurological loss that may lead to death. Chronic diseases like amyotrophic lateral sclerosis, Huntington's disease, Alzheimer's disease, and Parkinson's disease are associated with insoluble protein depositions and pose serious health challenges that may intensify in the coming decades. Current therapies only help to alleviate some of the physical or mental symptoms associated with neurodegenerative diseases, although there is currently no remedy for slow disease progression. In recent years, attempts have been made to discover a mechanism for neurodegenerative diseases and prospective treatment that may help mitigate aging effects and prevent these diseases. Natural products have been a constant source of new approaches for the treatment of neurodegenerative diseases, in particular plant alkaloids and polyphenolic compounds. Indopathy for Neuroprotection: Recent Advances highlights herbal treatments that are preferred over conventional treatments in some regions. Book chapters focus on the effects of various medicinal plants that have shown promise in reversing pathological symptoms of neurodegenerative disease and highlight the neuroprotective role of medicinal herbal phytochemicals and their mechanism of action. The book serves as a reference for pharmacology and herbal medicine scholars as well as healthcare workers interested in information about alternative and complementary therapies for neurological disorders.

Hippophae rhamnoides, also known as sea buckthorn is an ancient plant with modern virtues, due to its nutritional and medicinal value. Sea buckthorn is a spiny bush with long and narrow leaves, and orange-yellow berries. It is cold resistant, and native to Europe and Asia. All parts of Hippophae e.g. berries, leaves, and seed or pulp oils contain many bioactive compounds. They are a rich source of natural antioxidants such as ascorbic acid, tocopherols, carotenoids, fla-vonoids, while they contain proteins, vitamins (especially vitamin C), minerals, lipids (mainly unsaturated fatty acids), sugars, organic acids and phytosterols. Animal and human studies suggest that sea buckthorn may have various beneficial effects: cardioprotective, anti-atherogenic, antioxidant, anti-cancer, immunomodulatory, anti-bacterial, antiviral, wound healing and anti-inflammatory. Hippophae could also be used in human and animal nutrition. Therefore, it would be worthwhile to perform more scientific research on this medicinal plant and to promote its large-scale utilization.

This study presents nutritional and antimicrobial characteristics of seabuckthorn seed oil, extracted from berries of Hippophae salicifolia (4.3-4.9%) and H. rhamnoides (4.75-5.25%). Physicochemical analysis of seed oil gave: acid value, 4.0-4.7 mg KOH/g; saponification value, 184.3-230.2 mg KOH/g; peroxide value, 17.5-18.3 meq/kg; and unsaponifiable matter, 0.60-0.78%. The oil contained oleic acid (31.8-37.0%), linoleic acid (25.8-27.9%) and linolenic acid (14.1-17.8%), and thus showed predominance of unsaturated fatty acids (82.6-83.5% w/w) comprising of both polyunsaturated fatty acids (39.9-45.8% w/w) and monounsaturated fatty acids (36.9-43.6% w/w). Seeds of both species contained vitamin E (27.0-30.0 μg/g). Seed oil exhibited good antimicrobial property (growth inhibition zone diam, 4.0 mm) against Escherichia coli. Thus, owing to high content of linolenic acid and vitamin E and good antimicrobial property, seed oil can be exploited in pharmaceutical, cosmetic and nutraceutical preparations. Seed cake was rich in proteins and minerals and can be used as animal feed.

American foulbrood is a dangerous world-wide spread disease of honey bees caused by the Paenibacillus larvae bacterium. Antibiotic treatments are less effective and leave residues in bee products. It is therefore necessary to find an alternative, especially using natural ingredients such as plant essential oils, probiotics, fatty or organic acids. Two strains of P. larvae were used for this study: CCM 4488, a strain from the Czech collection of micro-organisms and a Slovak field strain which was isolated from infected bee combs and characterized on the basis of biochemical properties. Plant essential oils of sage (Salvia officinalis), anise (Pimpinella anisum), oregano (Origanum vulgare), caraway (Carum carvi), thyme (Thymus vulgaris), rosemary (Rosmarinum officinalis), clove (Syzygium aromaticum), camomile (Chamomilla recutita) and fennel (Foeniculum vulgare) were used for the testing of the inhibitory activity against P. larvae. Essential oils at amounts of 5 μl and 10 μl were applied to sterile discs on MYPGP agar; inhibition zone diameters were measured after 24-h incubation at 37 °C. The strongest inhibitory activity against both P. larvae strains was noted in case of the essential oils from oregano, thyme and clove; essential oils from camomile, rosemary and fennel showed no or weak antibacterial activity. Medium strong inhibition activity was recorded in case of previously untested essential oil from Carum carvi. There was a difference in sensitivity of both tested strains to essential oils. Our study confirmed that some essential oils can be used in the prevention of American foulbrood but further experiments aimed at their influence on physiological intestinal microflora of honey bees must be performed.

Hippophae rhamnoides L. (Elaeagnaceae) also known as seabuckthorn, is a thorny, deciduous, temperate bush plant native to European and Asian countries. In India, it is widely distributed at high altitude, cold arid condition of Ladakh (Leh and Kargil), Himachal Pradesh, Sikkim and Arunachal Pradesh. H. rhamnoides has been used for the treatment of several diseases in traditional medicine in various countries throughout world. In Ladakh, the Sowa Rigpa system (Amchi System of medicine) has been using the plant parts in different herbal formulations. However, more scientific data is needed to support the various health claims. The various in vivo study of seabuckthorn oil reported to have anti-inflammatory, antioxidant, antimicrobial, anti-ulcer properties and hepatoprotective. Seabuckthorn oil is a unique source of high valued oils emphasizing its potential as a dietary and medicinal supplement and has become noted for its generally high levels of nutritionally and medicinally important components. The major unsaturated fatty acids were linolenic acid (omega-3) (20-23%), linoleic acid (omega-6) (40-43%), oleic acid (omega-9) (19-22%) and palmitoleic acid (1-3%) while the major saturated fatty acid contents were palmitic acid (7-9%), stearic acid (3-4%) in seed oil. Seabuckthorn pulp oil contains approximately 65% combined of the monounsaturated fatty acid and the saturated fatty acid. Both the seed and pulp oils are rich in Vitamin-E and β-Sitosterol. In addition, the pulp oil contains especially high levels of carotenoids. This ancient plant with its powerful and healing synergies has much to contribute to the livelihoods of high mountain people by utilizing this kind of hidden treasure of the Himalayas. In this review discusses on traditional use, phy to chemistry and pharmacological data of the seabuckthorn oil.
It was previously reported that essential oils from aromatic plants have an antimicrobial activity against many bacterial pathogens [13]. We have conducted an in vivo experiment to study the effect of some aromatic plants and in particular to investigate the effect of oils extracted from these plants at the immune level and duodenal morphology. During the experiment 90 chicken broilers were divided in three experimental groups: control group (C), group 1 (G1) and group 2 (G2). The chicken broilers from group G1 had received feed with 0.05% incorporated oils extracted from savory (Satureja hortenis), mint (Mentha piperita) and sea-buckthorn (Hippophae rhamnoides). Group G2 received a premix of plants (savory, mint and sea-buckthorn) during daily feeding. The control group (C) received normal feed with no supplements. The amount of lysozyme detected at group G1 was doubled (28.55 mcg/cm 3) compared to G2 (13.2 mcg/cm 3) and the control (11.42 mcg/cm 3). The incorporation of extracted oils in food resulted in a powerful stimulation of intestinal mucous membrane, manifested by development of intestinal villi, the hypertrophy of villi, hyperplasic hypertrophy of capillary network and the stimulation of leukocytes infiltration. The muscular hypertrophic processes and leukocyte infiltration are visible in the endomesium and perimesium of the muscular tunic. Microscopical images of the G2 group taken from the duodenum sections suggest the stimulation of angiogenesis. The processes are however of smaller intensity in the G1 group. This work shows that essential oils extracted from plants improve the immune response and also are able to cause changes of the duodenal mucosa with beneficial effects for the animal.
The present study undertaken to study the cellular immune response in seabuckihorn fed White Leghorn broiler chickens which was evaluated by OTH reaction. Both the SBT fed groups showed higher DTH reaction recorded at 24 hr post challenge as compared to control group. Histopathological investigation revealed higher degree of lymphofollicular reaction in the challenged skin of birds from both SBT fed groups.
A study is performed on sea buckthorn oil and health of mucous membranes. Mucous membranes are constantly under the challenges of genetic deficiencies, disease, stress, ageing, side effects of medical treatments and environmental factors such as air and water pollutes. It is reported that clinical trials with larger number of patients are justified to more accurately pinpoint the conditions which may benefit from treatment with sea buckthorn oils.
Hippophae rhamnoides Linn., commonly known as sea buckthorn (family: Elaeagnaceae), grows wild in Asia and Europe. As one kind of Chinese traditional medicine, H. rhamnoides Linn. berry was effective in treating wounds, inflammation, mucous-membrane-related disorders and diseases such as cough, sputum, cancer and bacterial problem. In diabetes, H. rhamnoides Linn. affected not only the lowering of the blood sugar including fasting blood glucose and 2 h postprandial blood glucose, but also in treating the complications. H. rhamnoides Linn. had been shown to be effective in cell cultures, animal studies, and clinical practice. Although, H. rhamnoides Linn. had been shown to have positive effects in relieving symptoms, such as fatigue, dry mouth and dry eye in non-diabetic disease, whether it has the therapeutic effect on diabetes symptoms was still unclear. Studies have to be conducted to test and verify the effect of H. rhamnoides Linn. on symptoms in diabetes patients. On the whole, H. rhamnoides Linn. is a candidate for complementary diabetes therapy.
