The levels and activities of a number of plant secondary
metabolites (PSMs) are known to increase in response
to increase in stress. The Mongolian plants considered
to possess medicinal properties may contain novel
compounds since they are exposed to severe
conditions; such plants could become good candidates
for modern drug discovery programmes. Information
on distribution, palatability to livestock and opinion of
local people on their nutritive and medicinal values was
compiled for 15 plant materials from 14 plant species
considered important for medicinal purposes. These
plants were evaluated for nutritive value and PSMs:
tannins, saponins, lectins, alkaloids and cyanogens.
High levels of tannins were found in roots of Bergenia
crassifolia and in leaves of B. crassifolia, Vaccinium
vitisidaea and Rheum undulatum. High lectin activity
(haemagglutination) was present in B. crassifolia roots,
and leaves of R. undulatum, Iris lacteal and Thymus
gobicus contained weak lectin activity. Tanacetum
vulgare, Serratula centauroids, Taraxacum officinale
and Delphinum elatum leaves contained saponin
activity (haemolysis). Alkaloids and cyanogens were
not present in any of the samples. The paper discusses
the known medicinal uses of these plants in light of the
PSMs levels, and identifies plant samples for future
applications in human and livestock health, welfare and

Métabolites secondaires végétaux de quelques
plantes médicinales de la Mongolie utilisées pour
améliorer la santé et la production animale
Les niveaux et activités d’un certain nombre de
métabolites secondaires végétaux (plant secondary
metabolites, PSMs) sont connus pour augmenter à
la suite de stress croissant. Les plantes mongoles,
censées avoir des propriétés médicinales, pourraient
contenir de nouveaux composés puisqu’elles sont
exposées aux conditions environnementales rudes.
De telles plantes seraient de bons candidats pour des
programmes modernes de découverte de drogue.
Des informations sur la distribution, la sapidité pour le
bétail et l’opinion de la population locale concernant les
valeurs nutritives et médicinales ont été rassemblées
pour 15 matières végétales provenant de 14 espèces de
plantes considérées importantes dans des applications
médicinales. Ces plantes on été évaluées concernant
leur valeur nutritive et les PSMs: tannins, saponines,
lectines, alcaloïdes et cyanogènes. Des niveaux élevés
en tannins ont été trouvés dans les racines de Bergenia
crassifolia ainsi que dans les feuilles de B. crassifolia,
Vaccinium vitisidaea et Rheum undulatum. Une activité
élevée de lectin (hémagglutination) était présente dans
des racines de B. crassifolia, tandis que des feuilles de R.
undulatum, Iris lacteal et Thymus gobicus démontraient
une faible activité de lectin. Les feuilles de Tanacetum
vulgare, Serratula centauroids, Taraxacum officinale
et Delphinum elatum démontraient une activité de
saponines (hémolyse). Des alcaloïdes et cyanogènes
n’étaient pas présents dans ces échantillons. Cette
publication discute des applications médicinales
connues de ces plantes devant de niveaux PSMs, et
identifie des échantillons de plante pour de futures
applications au service de la santé des êtres humains et
du bétail, leur bien-être et sécurité.
The use of various herbs and medicinal plants has a
long history. They have been used since ancient times,
especially in oriental countries. However, the advent
of antibiotics in early 20th century led to decline in
their usage and waned interest in providing scientific
bases to their effects. The adverse effects of using
antibiotics and other synthetic compounds on human
and animal health and on product quality and safety
have regenerated interest in the fields of ‘phyto-
chemistry, phyto-pharmacology, phyto-medicine and
phyto-therapy’ during the last decade. The ban on the
use of antibiotics and other chemicals in livestock feeds
since 2006 by the EU, because of the risk to humans of
chemical residues in food and of antibiotic resistance
being passed on to human pathogens, has further
provided momentum to the research efforts on exploiting
plants, plant extracts or natural plant compounds as
potential natural alternatives for enhancing livestock
productivity. The plant kingdom might provide a useful
source of new medicines, pharmaceutical entities and
bioactive compounds that may be used for not only
treating human diseases but also for enhancing animal
production and health; and food safety and quality,
whilst conserving environment (13).
Plants have long been and continue to be the basis
of many traditional medicines worldwide. Asian
traditional medicinal systems such as traditional
Chinese medicine (TCM), Korean Chinese medicine,
Japanese Chinese medicine (kampo), Ayurveda from
India, Jamu from Indonesia are well known. Mongolian
traditional medicine, not much known to the world, is
an amalgam of traditional Tibetan medicine, Ayurveda
and Chinese medicine. Integrative medicine – the
combination of traditional medicine with conventional
or Western medicine could provide novel medicines
for treatment of both animals and human disease.
Bioactive compounds from plants could also be used
as feed additives for enhancing livestock productivity
and reducing environment pollutants such as methane
in the exhaled gas and nitrogen and phosphorus in urine
(13). The bioactivities in the plants are generally ascribed
to the presence of plant secondary metabolites (PSMs)
which could have beneficial or adverse effects (13, 17).
In recent times, there has been change in the perception
and several studies have been conducted on exploiting
the beneficial effects of these phytochemicals.
To form the basis for rational exploitation of medicinal
plants of Mongolia, we characterised some of the
medicinal plants for PSMs and chemical composition,
and the data are presented and discussed in this paper.
Material and methods
The samples were sun dried and brought to Germany
for analyses. For analysis of crude protein and fibre
fractions, the samples were ground to pass through 1
mm sieves; for the analysis of PSMs the samples were
ground to fine powder using a ball mill (Retsch MM200,
Haan, Germany). Crude protein (Kjeldahl method; N x
6.25) and ether extract were determined using AOAC
(1). Neutral and acid detergent fibre analyses were
conducted according to Van Soest’s fiber analysis (18).
Sodium sulphite and α-amylase were not used for the
determination of fibre.
Extractable total phenols, total tannins and condensed
tannins were determined in aqueous acetone (70:30,
acetone:distilled water) extracts as described by
Makkar (11). Total phenols were determined with Folin-
Ciocalteu reagent using tannic acid as a standard. Total
tannins were measured as the difference between total
phenols before and after tannin removal by adsorption
on insoluble polyvinylpyrrolidone (Sigma, Darmstadt,
Germany). Both total phenols and total tannins were
expressed as tannic acid equivalent. Condensed
tannins (CT) were measured using the butanol-HCl-iron
reagent (14) and expressed as leucocyanidin equivalent.
The biological activity of tannins was determined in a
bioassay developed in our laboratory. In this bioassay,
samples are incubated with and without polyethylene
glycol, PEG (MW 4000 or 6000) in syringes containing
buffered rumen liquor. The polyethylene glycol binds to
tannins making them inert, which leads to higher gas
production; the higher the increase in gas production,
the higher the biological activity of tannins (14).
Analysis of the lectin content was conducted by
haemagglutination assay in round-bottomed wells of
microtitre plates using 1% (v/v) trypsinised cattle blood
erythrocytes suspension in saline phosphate buffer, pH
7.0 (12). The haemagglutination activity was expressed
as the minimum amount of the material (in mg per ml
of the assay medium) which produced agglutination.
The minimum amount was the material per ml of the
assay medium in the highest dilution that was positive
Saponin activity was determined as haemolytic activity.
The sample was extracted in phosphate buffer saline
(PBS). An aliquot (50 µl) of the PBS extract was diluted
two-fold with PBS in separate wells of a microtiter plate
and was mixed with 50 µl of 3% red blood cell suspension
(from cattle blood) in each well and incubated at room
temperature for 2 h. A clear concentric circle around the
red blood cells indicated a non-haemolytic well, and the
spread of red colour in the well and absence of a clear
zone around red blood cells showed haemolysis. The
haemolytic activity was expressed as the inverse of the
minimum amount of saponin extract per ml of the assay
medium in the highest dilution that started producing
The presence of alkaloids was assessed by extracting
the finely ground materials in chloroform and application
on thin layer chromatography (TLC) plates (Silica gel G).
Dragendorff reagent was used for detection of alkaloids
The determination of cyanogens was based on
evolution of hydrocyanic acid from the sample and
reduction of sodium picrate on a filter paper to a
red-coloured compound, in proportion to its amount
evolved and measurement of absorption at 510 nm
using a spectrophotometer (5).
Results and discussion
Plants are good sources for the discovery of
pharmaceutical compounds and medicines. Natural
products could be potential drugs for humans or
livestock species, and also these products and their
analogues can act as intermediates for synthesis
of useful drugs. Bioassay directed isolation and
synthesis of analogues have long been appreciated as
the effective approach for development of new plant
Levels of secondary
environmentally induced as well as genetically
controlled. The secondary metabolites are also called
as plant defensive compounds since these have been
evolved to deter pathogens or herbivores such as insects
and mammals. The plants growing on low nutrient
soil or in harsh conditions are often more dependent
on evolved chemical defences. The Mongolian plants
grow under harsh conditions of extremely low and high
temperatures and thus could contain PSMs with a wide
range of interesting activities.
The common names of plants, their distribution in
Mongolia and reported medicinal uses are listed in
table 1. This table also contains information on farmers’
opinion on the palatability of the leaves by livestock
and on their nutritional value. The leaves in particularly
of Artemisia frigida and Taraxacum officinale are highly
palatable by animals. The leaves studies are found
in different regions of Mongolia and are considered
to posses wide medicinal values, ranging from
antimicrobial and anthelminthics to kidney- and liver-
stimulating effects (Table 1).
metabolites are both
The crude protein (CP) content of the leaves varied from
6.3 to 24.5%. The CP content was lowest (3.3%) in root
sample of Bergenia crassifolia (Table 2). The leaves of A.
frigida and T. officinale were reported by farmers to have
high nutritional value. The CP content of these leaves
considered good for livestock had high CP values (15.6
and 24.6% respectively); although mature leaves of A.
frigida have a lower CP content (9.0%).
Tannins are polyphenolic compounds and have a wide
range of effects varying from decreasing availability
of proteins and other nutrients including amino acids
and minerals to protecting ruminants from bloat,
enhancing rumen bypass protein, enhancing meat
quality and decreasing helminth infestation. Tannin
level and activity was very high in B. crassifolia roots
and leaves of B. crassifolia, Vaccinium vitisidaea
and Rheum undulatum. A moderate tannin activity
(33.4% increase in gas on addition of PEG) was
present in Thymus gobicus. Tannins are also known
to have antimicrobial, anthelmintic, antimutagenic,
antiinflammatory and antioxidant properties. A
number of tannin-rich tree leaves and browses have
been evaluated and found to be effective in reducing
faecal egg worm and enhancing livestock productivity
(13). Parasitism by gastrointestinal nematodes is one
of the major constraints on livestock production,
especially when the nutritional status of the animals
is poor. Subclinical infections of gastrointestinal
nematodes decrease feed intake, body-weight gain,
and milk and wool production. In subtropical and
tropical areas of the world where the animals are on
low quality feeds and have poor nutritional status,
mortality and morbidity due to nematode infection
are widespread. There is a growing awareness that
chemical anthelmintic treatment, on its own, may not
provide a long term strategy for managing parasites
in grazing animals. The widespread development and
prevalence of resistant strains of nematode parasites
and public concern over drug residues excreted in
animal products have stimulated efforts to identify
and use plant-based anthelmintic compounds;
tannin-containing plants and tannins could potentially
be natural anthelmintics.
Among the above-mentioned four plants identified
as containing substantial amounts of tannins, only T.
gobicus has been used by farmers as an anthelmintic
to dispel intestinal worms. The presence of etheric oil
compounds such as thymine, eugenol and carvacrol in
this plant could also be responsible for its anthelmintic
effects. The other three tannin-rich plants B. crassifolia,
Vaccinium vitisidaea and Rheum undulatum also hold
potential for reducing the intestinal worm load in
livestock and increasing their productivity. Studies on
evaluation of these plants as anthelmintics are being
conducted in our laboratory in Mongolia. Similar use
of these plant materials for other properties stated
above for tannins also needs investigation. The use of
B. crassifolia root and leaf extracts as mouth cleaner in
Mongolia, their known astringent effect and their use for
curing infectious disorders of the gastro-intestinal tract
(Table 1) could be attributed to the presence of high
tannin levels and activities in this plant. The astringent
effect of tannins is a well established phenomenon
In Mongolia, farmers also use A. frigida, Tanacetum
vulgare, Iris lacteal, and Stellera champaejasme leaves
as anthelmintics (Table 1), although tannin levels were
low in these leaves. The data on PSMs in this study
could not provide answer to the use of these leaves as
anthelmintics. This effect could possibly be due to the
presence of some other non-tannin bioactive moiety
such as bromelain present in pineapple leaves (13).
Enhancement of the nutritional status of animals has
also been shown to decrease the burden of intestinal
worms due to increased immunity (7). Artemisia frigida
is highly palatable to livestock and has reasonably high

crude protein level (young leaves 15.6% and mature
leaves 9.0%). The effectiveness of this plant against
intestinal worms could possibly be due to the high
nutritional quality and high intake of this plant material,
thereby enhancing nutritional status of animals.
The use of tannins for reduction of methane (a
greenhouse gas) production from ruminants is being
considered (3). Recently studies conducted in our
laboratory have shown a high correlation between the
tannin activity and methane reducing potential of these
medicinal plants from Mongolia. Tannin containing
plants could possibly be used to prevent diarrhoea in
Saponins are steroid or triterpene glycoside compounds
present in a number of plants. These were present
in T. vulgare, Serratula centauroides, T. officinale and
Delphinum elatum leaves (Table 2). Saponins have also
been known to have several health beneficial effects, for
example, enhancement of immunity, reduction in blood
glucose and other antidiabetic effects, and reduction
in blood cholesterol (4). The plants T. officinale and D.
elatum are used in Mongolia for reducing blood sugar
and blood pressure, and this study has shown that
these plants contain saponins, which could possibly
be responsible for these beneficial effects. Saponins
also have anti-protozoal effects and could potentially
be used for controlling protozoal diseases. This group
of PSMs also has strong antifungal, antinematode,
molluscicidal, and insecticidal properties (2, 4, 20).
The use of T. vulgare for killing scabies, fleas and lice
as practiced in Mongolia could possibly be attributed
to the presence of saponins. In addition, the saponin
containing Mongolian plants could find applications
for reducing emission of methane from ruminants and
enhancing livestock productivity (20).
Among the PSMs determined, alkaloids and cyanogens
were not detected in any of the samples analysed
(Table 2). Alkaloids and cyanogens have been reported
to have both detrimental and beneficial effects (17).
Lectins or haemagglutins are sugar-binding proteins.
Lectin activity was present in the leaves of I. lacteal,
R. undulatum, T. gobicus and B. crassifolia roots; lectin
activity being highest in B. crassifolia roots. Traditionally
lectins have been described as toxic and antinutritional
factors; however major developments have taken
place during the last decade showing a number of
potential applications of plant lectins in biomedical and
bioscience fields. To name a few are applications as
gut-, metabolic-, hormone- and immune-regulators
and their use for protection of intestine against the
adverse effects of radio- and chemo-therapy used
in cancer therapy (16). Lectins present in leaves of

in lectin activity could be an interesting candidate for
Based on the known activities of secondary metabolites,
this study has provided explanation for some of
the medicinal uses of the plants for which the local
population use them. This study has also identified
plant materials such as B. crassifolia root which is rich
in tannins and lectins; B. crassifolia, V. vitisidaea and
R. undulatum leaves which are rich in tannins; and T.
vulgare, S. centauroids, T. officinale and D. elatum leaves
containing saponins, for future investigations leading to
their various applications in human and animal health,
production and welfare. Future studies should also be
directed towards exploring other phytochemicals such
as flavonoids, flavanones, phytoestrogens, essential
oils etc. in the leaves and other parts of the plants
especially roots, which are also used in the traditional
Mongolian medicines to a considerable extent.
