INTRODUCTION
Jojoba is typically grown in dry and semi-arid climates
like―United States, Israel, Mexico, India, and South Africa‖.
The yield of the oil the jojoba plant is roughly ‗1818 kg/ha‘
which is somewhat lesser than that of the Jatropha plant but
greater than the yield of the Camelina plant which is 3 of its
mainly significant non-edible oil today1. This plant can be
utilized to avoid desertification in some regions of India, it
may serve a dual purpose: environmental and economic.
The jojoba plant is an evergreen shrub belonging to the
family Buxaceae. It serves as one of the constituents in the
formation of an extremely rare combination of high-
molecular-weight, monounsaturated, esters range of C34, to
C50. Much research has been undertaken to assess the
endurance of the Jojoba plant, it has been found that it can
withstand harsh circumstances such as salt, heat, and
drought. It is important to remember that when cultivated in
severe circumstances such as those found in the desert, the

jojoba plant must increase its output. When fully grown, the
plant may reach a height of around 1 m and is readily
distinguished by its "thick, oval shape, bluish-green leaves,
and dark brown nut-like fruit". Jojoba oil accounts for
almost half of the dry weight of the seed and it is a
combination of monounsaturated, C20, and C22 alcohols
and acids with bounded on the side with ester link Because
it is structurally similar to ‗sperm whale oil,' jojoba oil is
presently the only unsaturated liquid wax that can be
extracted in significant volumes from plants. Jojoba oil has
been used as a substitute for sperm whale oil since the 1970s
(spermaceti wax).The composition of jojoba oil is distinct
from that of other vegetable oils due to the virtually total
lack of glycerin. The properties of this oil were previously
recognized in history when natural remedies were used to
cure ailments such as "renal colic", chaffed skin(Hatfield,
2004), sunburned, headaches, wounds, sore throat, and hair
loss". Furthermore, jojoba oil is a unique source of smooth
monounsaturated, alcohols such as "15-tetracosenol, 13-
docosanol, and 11-eicosanoid". As previously said, jojoba
oil is produced by a combination of esters, which endows
this peculiar oil with properties like high conductivity,
sulfurization adaptability, and ease of hydrogenation. In
California, jojoba oil was used for several diseases,
including "kidney and liver issues, cancer therapy, obesity,
parturition, superficial wound healing, sore throat, warts,
psoriasis, sunburn, acne, and treatment of poison ivy
exposure." In the pharmaceutical industry, jojoba oil is often
used to restore normal hair and skin health, notably in
cosmetics3 .The leaf extract works as an anti-inflammatory
agent when combined with extracts from other plants to
relieve sensitive skin tension. Body oil, cleaning creams,
bath oil, cleansing pads, cleansing scrubs, facial oils, hair
conditioners, nourishing face creams, hair oils, makeup
removers, and other jojoba cosmetic goods are now on the
market. The applications of jojoba oil include "medicines,
lubricants, cosmetics, heating insulators, high-pressure
lubricants, foam control agents, heating oil, plasticizers,
transformer oils, fire retardants," and many others4.
Jojoba oil and derivatives
Economically, the Jojoba oil industry is stronger than
constantly since its uses continue to expand, particularly in
the beauty and pharmaceutical, industries. Many research
shows the significant distinction between this one-of-a-kind
oil and other vegetable oils. This information may be proven
by considering the expected global Jojoba oil demand,
which is roughly 200,000 tones, which is far greater than
present output, the use of Jojoba seed after extraction
method is being carefully researched, particularly its
primary constituent called Simmondsia. Simmondsia
decreases food intake by inducing satiation, which can be
prevented by combining it with a particular receptor
antagonist. Cokelaere. established that Simmnondsin's
anorexia-inducing effect is associated with mild pancreatic
enlargement and activation of interscapular brown adipose
tissue. Ham confirmed this conclusion by feeding Beagle
dogs two different amounts of Jojoba meal. When 2.7
percent Jojoba meal was added to the diet, neither the dogs'
body weight nor the food was completely digested.
However, the 8.1 percent dose affected body weight and
food digestion(Sánchez et al., 2016). As previously said, 50
percent of the seed is turned into a Jojoba meal during the
extraction process, thus various applications should be
considered to maximize the value of this waste.
Chemical constituents
Jojoba oil is usually referred to as a liquid wax rather than
fat or oil since it contains around 98% pure
waxes(Vanhercke et al., 2013) ―mainly wax esters, alcohols,
hydrocarbons, and free fatty acids‖, vitamins, and sterols,
with a few, triglyceride esters.
Jojoba wax
An analysis of the jojoba plant's various organs for the
existence of wax indicated that the seeds contain the
majority of the plant's wax content, "accounting for" about
5052 percent of the total seed weight(Rowland and
Domergue, 2012). Jojoba wax is mostly made of esters, with
minor amounts of hydrocarbons, free acids, and free
alcohols.
Wax esters
In trace amounts, many more wax esters and free fatty alcohols
may be found. It was considered that jojoba wax esters, was
made up of alcohol and acid. Newly discoveries disparity
between the measured and predicted results from a random
connection of alcohols and acids. For example, (acid/alcohol,
percent experimental (percent random)): (C20:1/C'20:1, 28.0
percent (31.8 percent)), (C20:1/C'22:1, 10.3 percent (5.7
percent)), (C22:1/C'20:1, 41.4 percent (32.0 percent)),
(C22:1/C'22:1, 1.9 percent (5.7 percent)), demonstrating that
eicosenyl do-senate ester is preferable. These combinations
show that plants favor certain relationships that are related to
their genome. From an analytical standpoint, this discovery is a
significant tool to detect contaminated oil and distinguish real
Jojoba wax from its synthetic replacements. In the latter
case(Vanhercke et al., 2019).
Free fatty acids and alcohols
According to reports, the natural oil includes trace amounts
of alcohols(1.11 percent ),and free fatty acids are shown in
table 1 (Carrín and Carelli, 2010).

Sterols
Several studies were conducted on the jojoba oil sterol
content(El-Mallah and El-Shami, 2009). The sterols fraction
is mostly composed of cholesterol, -Sitosterol, campesterol,
stigmasterol, and isofucosterol. The majority of these
compositions are listed in table 2.

Molecular structure
Each component molecule of jojoba oil has two double
bonds as well as an ester group on its surface. According to
the NMR spectroscopy results, a 5.5-ppm shift is seen for
hydrogen atoms near the double bond, and a 2.1-ppm shift is
observed for the allylic hydrogen in the raw material. Shifts
of 4,ppm and 2.15,ppm have been recorded for hydrogen
atoms in the Y position to oxygen and a carboxylic group,
respectively, in the presence of oxygen. In the atomic
weights of aliphatic hydrogen and methylene groups, there
are shifts of 1.11 and 0.08 ppm(Jing et al., 2019).
Physical properties
Oil extracted from jojoba seeds is often a low-acid, light-
golden fluid requiring minimal to no processing. It is rancid-
free and non-volatile. However, it remains mostly
unchanged after four days of frequent heating to 285 °C or
370 °C. Its boiling point increases to 418°C at a pressure of
757 mmHg under nitrogen, then rapidly decreases to a
constant 398°C. It isn't always necessary to neutralize the
oil, and commercial processes can be used to disinfect a
moisture-clear solution. According to the Gardner scale, a
15-30 minute treatment with 2-5 percent Filtrol 105 at
100°C decreases the color from 7 to 3.The cleaning earth
selected should not eliminate the oil's natural antioxidants. It
determined the following associations by measuring the
density (d, g ml-'), viscosity (11,cP), and refractive index (n)
of jojoba oil at various temperatures(Magzoup, 2021).
n = 1.47391 - 0.000360t
d = 0.88208- 0.000655t
q = 0.004995 exp(2646/ T)
T is in degrees C, and with is in degrees K. The ratio of
jojoba oil is 225, according to Eq. 3. Measured the
compressibility, viscosity, and density of jojoba oil at
temperatures ranging about 25 to 120°C and pressures
ranging from 1 to 2000 bar. The specific conductivity values
of jojoba oil are equivalent to those of oleic acid in the
temperature range of 34140 °C. The neutrality of jojoba
oil, on the other hand, is a plus.
Chemical properties
Chemical Properties of oil have two double bonds at -9
locations on both the acid and alcohol sides, isolated by an
ester link. While double bonds in common plant oils are
generally near together, they are far away and irregular from
the center in jojoba molecules. Several studies have shown
J. Pharma. Bio. Med., 01 (01) 2022. 27-34 DOI: 10.xxxxx/jpbm.001.01.0004
30
that these three active sites are the source of a diverse
spectrum of complexes and end products with a variety of
physical and chemical characteristics(Price, 2003).
Cis/Trans Isomerization
The trans isomer of jojoba is more thermodynamically,
stable than the cis isomer. The process has never been
economically relevant, most likely because partial
hydrogenation may produce the same outcomes while also
providing more oxidation stability. Wozniak and Alfandary
were the first to report on the geometrical isomerization of
jojoba oil under various conditions utilizing selenium and
NO2 catalysts. The final product had melting points ranging
from 36 to 42 degrees Celsius. If required, adequate
adjustment of the working conditions may enable the
production of a material with a melting point close to that of
the typical human body temperature. Galun and colleagues
subsequently reported jojoba oil's heat and photosensitized
isomerization. The use of sensitizers allows for the
absorption of light at wavelengths of 366 nm or higher,
allowing for the acquisition of the isomerized form of jojoba
oil. This is based on the fact that when heated to a
sufficiently high temperature, the cis isomer may change to
the transform, and as a consequence, the double bonds in
jojoba oil absorb light with wavelengths shorter than 200
nm. 2021, 13, 1711 9 of 22 5.2 polymers
Hydrogenation. Hydrogenation is a popular process for
improving the properties of vegetable and animal oils. The
oil is completely hydrogenated, resulting in exceptionally
hard, very glossy, pearly white crystalline laminae. Solid
wax has been suggested as a component of polish waxes,
carbon paper, fruit waxing, and candle components. solvent-
extracted jojoba oil and cold-hydraulic pressing of jojoba
seeds jojoba oil Except for the melting point, the results
showed no discernible change between the two
hydrogenated forms. Those acquired using cold-hydraulic
pressing have a melting temperature of 6768 C, but those
produced through solvent extraction have a melting
temperature of 7476 C(Thakur, 2013).
Phosphorylation
Di alkyl phosphates are high organic phosphorus esters with
unusual characteristics that have significant economic
potential. As a result, they've been suggested for usage in a
wide range of applications.They has a high potential as
plasticizers due to their greater stability and other
distinguishing characteristics. Several dialkylphosphates can
be used as softeners, flame retardants, heat transfer media,
and textile treatment agents in general. Initial experimental
results on the phosphorylation of jojoba oil with different
di-alkyl-phosphates, using tert-butyl, per benzoate as a
radical activator have been reported in the journal
Phytochemistry. Because the average ester chain in jojoba
oil has two double bonds, the final product may include up
to two phosphorus atoms per chain as a result of the double
bond structure(Mumtaz et al., 2020).
Oxidation, Ozonolysis, and Epoxidation
Up to a reasonably high temperature, jojoba oil has strong
thermal stability. In general, cosmetic compositions using
jojoba oil have higher oxidation stability compared to other
lipids that have been used for this reason. A comparison of
the oxidative stability of sperm whale oil, jojoba oil,
carnauba wax esters behenylarachidate, and, Limnanthes
Douglass wax esters indicated that jojoba oil had the highest
oxidative stability when compared to the other oils. Kampf
investigated the rapid oxidation of jojoba oil, as well as
stripped and bleached oils. He discovered that jojoba oil
includes natural antioxidants that contribute to the oil's
remarkable oxidative stability. The loss of these
antioxidants from the oil by bleaching or stripping results in
a significant decrease in oxidative stability. Plasticizers and
stabilizers for polyvinyl chloride polymers are now made
from unsaturated glyceride epoxides and simple fatty acid
esters. To determine the structure of unsaturated molecules,
such as those present in jojoba oil, the method is known as
ozonolysis may be used. Jojoba Ozonides, in particular, and
Ozonides in general, are viable intermediates for a broad
variety of synthetic routes. Previous research conducted by
Zabicky employed ozone to get intermediates for the
synthesis of many derivatives that are often used in the
pharmaceutical industry (Tomkinson, 2003).
Extraction methods
Pressing of Jojoba seedsis often followed by hexane,
extraction of the crushed Jojoba meal. Because between 3%
and 8% of the oil cannot be recovered just by mechanical
pressing, a combination of mechanical, pressing, and
organic solvent, extraction is necessary. Table 3 shows the
composition of the whole seed, Dehulled whole seed. The
seed is primarily constituted of crude oil and carbohydrates,
and the major objective of the extraction technique is to
recover the maximum amount of oil feasible, which
accounts for around half of the entire seed weight.
Additionally, the extraction approach is limited to solvent
sag hexane. The most significant drawback is the amount of
solvent and time needed for the operation, which makes it
economically inefficient. There are also significant
environmental limits as a result of the current extraction
process's use of harmful solvents, and several attempts have
been undertaken to develop more environmentally friendly
ways of generating Jojoba oil. One of these methods is to
J. Pharma. Bio. Med., 01 (01) 2022. 27-34 DOI: 10.xxxxx/jpbm.001.01.0004
31
extract Jojoba oil using supercritical fluids, such as CO2,
owing to the advantages of CO2, as a solvent, such as its
cheap cost and complete inertness. However, the use of high
pressures makes this approach financially unattractive. As a
consequence, additional co-solvents such as ethanol or
propane may be used to increase CO2 solubility in Jojoba
oil. The fundamental disadvantage of utilizing ethanol as a
co-solvent is that it remains in the oil phase upon
depressurization and may alter the qualities of the final
extracted product if not adequately eliminated. The primary
drawback of propane is its flammability, which may be
managed at specific propane/CO2/air combination
proportions(Shu et al., 2020).
Table4 lists the many techniques of extracting jojoba oil.
The maximum extraction yield is determined by the amount
of oil in the jojoba seed, which in many situations is
somewhat greater than 50%. Furthermore, the yield obtained
by mechanical pressing might be enhanced by using organic
solvents to ensure that all the extractable chemicals are
extracted from the jojoba seed.

Direct Use and blending
One of the key reasons for Jojoba oil's high price is the
variety of uses in the chemical industry and fine chemicals.
These uses are contingent upon the physical and chemical
characteristics of the oil. As a result of these distinguishing
characteristics, the oil has a well-defined structure that is
associated with a high degree of purity. Additionally, Jojoba
oil has great oxidation resistance, stays liquid at room
temperature, and has a high polymerization and
hydrogenation potential. Habashy. observed that Jojoba oil
reduces carrageen in-induced paw edema due to its anti-
inflammatory properties. Because jojoba oil inhibited the
production of prostaglandin E2 (PGE2) in inflammatory
exudates, ancient peoples of the American continents used it
to treat inflammatory illnesses. Jojoba oil is broken down by
lipases to create 11-eicosenoic acid, which leads to the
release of free fatty acids, which reduces PGE2 generation.
Giurgiu‘s. also used jojoba oil to enhance chitosan
J. Pharma. Bio. Med., 01 (01) 2022. 27-34 DOI: 10.xxxxx/jpbm.001.01.0004
32
antibacterial activity against two distinct pathogens,
Staphylococcus Aureus, and Bacillus Subtilis. This raises
the potential for food safety and several biological
applications for chitosan. Additionally, evaluate the use of
jojoba oil as a substitute collector for the selective
separation of apatite and calcite minerals in an acid medium
without the use of depressants. For this experiment, the
optimal concentration of Jojoba oil was 200 mg/l. When
used with conventional sunscreens, this combination
minimizes unpleasant skin and systemic reactions induced
by transdermal absorption(Derhy et al., 2020).
Pharmacological properties
Analgesic, anti-inflammatory, antipyretic activities
Jojoba oil was studied for its anti-inflammatory properties in
both acute and chronic skin irritation. It was proven that
jojoba oil might be useful in lowering edema and relieving
pain caused by heat and sunburns. Jojoba oil's anti-
inflammatory activity was due to the inhibition of both
lipoxygenase and cyclooxygenase enzymes. This study is
supported by a controlled clinical trial examining the short-
term effects of jojoba liquid wax as a local treatment for
napkin rash(Shenefelt, 2012). The results were compared to
standard treatment, which included 'acetonide, nystatin,
triamcinolone, gramicidin, and neomycin'. Jojoba liquid
wax was demonstrated to be equally effective as that combo
in treating diaper rash. However, since jojoba lacked
pesticides, it was considered safer.
Topical Preparations
Jojoba was utilized to boost the efficiency of medications
used to treat skin conditions in topical formulations.
Previous research discovered that jojoba oil may be able to
solubilize lycopene, an essential antioxidant that is insoluble
in both water and oil. Because of the enhanced solubility,
lycopene may now be formulated into liquid and transparent
medicinal solutions. It is feasible to explain the successful
fabrication of micro emulsions using jojoba wax as the oily
phase and a variety of surfactants and co surfactants, where
the amount of jojoba oil dictated the transition from water-
in-oil to bicontinuous and oil-in-water structures. The study
found a considerable lessening in dryness and skin irritation
produced from benzoyl peroxide based on the emollient
impact, anti-inflammatory, and antibacterial characteristics
of jojoba oil. It increased the therapeutic impact.Because of
its moisturizing and anti-inflammatory properties, jojoba
oil-based, methotrexate-loaded, micro emulsion has been
shown safe and effective in psoriasis treatment. Patients
with severe psoriasis responded better to an oil-based micro
emulsion containing the synthetic retinoid tazarotene
compared to the commercial version, with fewer side effects
and a twofold increase in tazarotene skin deposition. Jojoba
oil was used to successfully generate stable viral solid lipid
nanoparticles. The produced nanoparticles were stable and
had a high valacyclovir entrapment efficiency, suggesting
that they might be an efficient delivery strategy for treating
viral infections in people. Previous research has shown that
jojoba oil may be used as an excipient in a variety of topical
antifungal treatments(Alexander et al., 2013).
Cosmetic Products
Jojoba oil has been reported to be used as a conditioning
agent due to its emollient properties. Jojoba oil was added to
thioglycolate-based straightening emulsions to strengthen
the hair fiber by allowing for reduced protein loss, threads
protection, and increased breakage resistance. Touitou and
Godin created skin-non-penetrating sunscreens (NPSUN) as
innovative photo protection against UV-damaging radiation
to capitalize on jojoba oil's molecular structure. The idea is
to build new filters by conjugating jojoba oil with UV
sunscreen molecules in the form of methoxycinnamate. The
created NPSUNs exhibited great skin substantivity,
minimizing the need for frequent application, while
methoxycinnamate-NPSUN did not penetrate the skin in
vitro for 24 hours(Touitou and Godin, 2008).
Other Activities
Jojoba oil is also demonstrated to protect against oxidative
damage caused by hyperglycemia. Cyanogenic glycosides
and other components found in the seed extract greatly
decreased ROS and caspase-3 activation and boosted
antioxidant defense by lowering p22phox and increasing
nuclear factorsan activity that may be beneficial in the
battle against diabetes. Jojoba oil may help prevent or cure
diabetes due to its antioxidant properties. Similarly,
jojobenoic acid, which is present in alcoholic seed extract,
has been proven to protect rats' livers against FB1-induced
hepatotoxicity. A previous study confirmed similar results,
revealing that jojoba seeds significantly decreased body
weight, fat mass, insulin resistance, oxidative stress, hepatic
steatosis, and renal issues. Jojoba seems to have a
preventive impact on metabolic syndrome, according to the
data. Clarke and Yermanos were the first to investigate the
lowering effect of jojoba oil on serum cholesterol levels in
rabbits, finding that blood cholesterol levels were reduced
by 40% in rabbits given a diet containing 2% jojoba oil and
1% cholesterol for 30 days, compared to rabbits given 1%
cholesterol alone. Concurrent therapy with jojoba oil and
fipronil decreased fipronil's toxicity in the liver, brain, and
kidney while improving antioxidant status, apoptotic rate,
and histological alterations. This positive effect was
established by lowering malondialdehyde (MDA) and nitric
J. Pharma. Bio. Med., 01 (01) 2022. 27-34 DOI: 10.xxxxx/jpbm.001.01.0004
33
oxide (NO) levels in the liver, brain, and kidney while
raising glutathione (GSH) levels and superoxide dismutase
(SOD), and catalase activity (CAT) (Kakarla et al., 2005).
CONCLUSION
The tasteful and specialized characteristics of jojoba oil
make it a widespread fundamental restorative fixing. The
compound construction of jojoba oil is not quite the same as
other vegetable oils. During capacity, fats might turn into
rank due to Peroxide development at the two fold bonds by
environmental oxygen and hydrolysis by microorganisms
with the freedom of free acids. Low Peroxide values give a
reasonable rule relating to jojoba oils a great period of
usability. Since jojoba oil doesn't oxidize or become rotten,
it tends to be added to different oils to expand their
timeframe of realistic usability. Saponifiable substances are
those that can be changed over into cleansers. The higher
the Saponification number of a fat liberated from dampness
and Unsaponifiable matter, the more dissolvable the
cleanser that can be produced using it. To that end it is
utilized from making specialty cleansers, shampoos, hair
conditioners, lotions, shaving creams, and so forth The
Corrosive worth of Jojoba oil is short of what one, and the
worth doesn‘t change with time, so it very well may be
presumed that it has a long timeframe of realistic usability,
which is a significant boundary asfar as the surface-level
worth of oil is concerned. The low Corrosive Worth,
moderate Iodine Worth and Saponification Number, Less
Unsaponifiable matter, and Peroxide Worth make jojoba oil
particularly valuable for corrective applications. It is a
characteristic emollient, making skin gentler, cleaner, and
generally round better. Since jojoba is miscible with sebum,
it frames an extremely flimsy, non-oily, lipoid layer of
jojoba and sebum when it is applied to the skin.

Jojoba (Simmondsia Chinensis (Link) Schneider) is one of the xerophyte plants belonging to Simmondiaceae family, and has unique botanical characteristics, like leathery leaves and deep root systems. It can thrive in arid conditions and withstand even the harshest of environments. Marginal lands are areas with limited agricultural potential due to poor soil quality, water scarcity, or other factors. These lands are often overlooked for agriculture, leading to environmental degradation and economic stagnation. Jojoba is a versatile plant that thrives in harsh conditions and plays a crucial role in preventing soil erosion. Its unique adaptation makes it a valuable asset in various ecosystems and in developing marginal lands. Various factors affect jojoba growth in marginal lands, i.e., soil quality, environmental conditions, and genetics, which play important roles in jojoba productivity. It provides a sustainable income for poor communities in marginal lands and is an ideal grazing source for various animals in dry areas.

The way to successfully upgrade a phosphate ore is based on the full understanding of its mineralogy, minerals surface properties, minerals distribution and liberation. The conception of a treatment process consists of choosing the proper operations with an adequate succession depending on the ore properties. Usually, froth flotation takes place in phosphate enrichment processes, since it is cheap, convenient, and well developed. Nevertheless, it is a complex technique as it depends on the mineral's superficial properties in aqueous solutions. Aspects such as wettability, surface charge, zeta potential, and the solubility of minerals play a basic role in defining the flotation conditions. These aspects range from the reagents type and dosage to the pH of the pulp. Other variables namely particles size, froth stability, and bubbles size play critical roles during the treatment, as well. The overall aim is to control the selectivity and recovery of the process. The following review is an attempt to add to previous works gathering phosphate froth flotation data. In that sense, the relevant parameters of phosphate ores flotation are discussed while focusing on apatite, calcite, dolomite, and quartz as main constituent minerals.

This chapter intends to summarize the chemistry, biological activities, methods of identification and quantification, possible interactions, and industrial and pharmaceutical applications of plant lipids. Plant lipids are naturally occurring functional and structural components, which serve as permeable barrier to external environment of cells. The compositions and functions of plant lipids vary depending on the type of plant. However, lipids are complex structures; therefore, there are various ways to define and classify lipids. The plant lipids play major role in energy storage and signaling and include fatty acids (FA), triacylglycerols, phospholipids, waxes, galactolipids, sphingolipids, tocopherols and tocotrienols, carotenoids, sterols, fat-soluble vitamins, and other compounds. Different procedures of spectroscopy like ultraviolet visible (UV) spectroscopy, mass spectrometry (MS), nuclear magnetic resonance (NMR) spectroscopy, and infrared (IR) spectroscopy along with liquid chromatography, paper chromatography, column chromatography, and gas chromatography are used to determine the structure of plant lipids molecules. The plant lipids vary in their occurrence, application, and utilization either as food, pharmaceutical, or other industries depending on their specific type. Moreover, the aim of this chapter is to compile the essential role and impact of plant lipids on human life and their application in different industries.

Society has come to rely heavily on mineral oil for both energy and petrochemical needs. Plant lipids are uniquely suited to serve as a renewable source of high-value fatty acids for use as chemical feedstocks and as a substitute for current petrochemicals. Despite the broad variety of acyl structures encountered in nature and the cloning of many genes involved in their biosynthesis, attempts at engineering economic levels of specialty industrial fatty acids in major oilseed crops have so far met with only limited success. Much of the progress has been hampered by an incomplete knowledge of the fatty acid biosynthesis and accumulation pathways. This review covers new insights based on metabolic flux and reverse engineering studies that have changed our view of plant oil synthesis from a mostly linear process to instead an intricate network with acyl fluxes differing between plant species. These insights are leading to new strategies for high-level production of industrial fatty acids and waxes. Furthermore, progress in increasing the levels of oil and wax structures in storage and vegetative tissues has the potential to yield novel lipid production platforms. The challenge and opportunity for the next decade will be to marry these technologies when engineering current and new crops for the sustainable production of oil and wax feedstocks.

In the present study, a novel model is proposed to evaluate the lower flammability limit (LFL) of alkane diluted with CO2. The LFL model is based on flame phenomenon simulation (FS-LFL). The model consists of combustion, turbulence, and igniter models, which are used to characterise the combustion based on the chemical kinetics and CFD, which is not feasible with traditional methods. The flame simulation phenomenon was validated by contrast with experiment and same criterion of flammability limit in the experiment was adopted. The FS-LFL model was used to predict the LFLs of a propane-CO2 mixture and propane at various temperatures. The model performance was analysed by comparing the results with experimental data and predictions obtained from existing methods. The AARDs between the predicted and experimentally determined LFLs of the propane-CO2 mixture are 0.34%, 1.19%, and 1.35% at 30°C, 50°C, and 70°C, respectively. The model also has a good predictive power with respect to the LFLs of propane at initial temperatures ranging from 30°C-300°C, with an AARD of 2.10%. When the dilution of CO2 is 90%, the model yields a better result due to the utilisation of the chemical kinetics mechanism. This result is instructive for the use of this method in the prediction of upper flammability limits.

The world is hungry for energy. Plant oils in the form of triacylglycerol (TAG) are one of the most reduced storage forms of carbon found in nature and hence represent an excellent source of energy. The myriad of applications for plant oils range across foods, feeds, biofuels, and chemical feedstocks as a unique substitute for petroleum derivatives. Traditionally, plant oils are sourced either from oilseeds or tissues surrounding the seed (mesocarp). Most vegetative tissues, such as leaves and stems, however, accumulate relatively low levels of TAG. Since non-seed tissues constitute the majority of the plant biomass, metabolic engineering to improve their low-intrinsic TAG-biosynthetic capacity has recently attracted significant attention as a novel, sustainable and potentially high-yielding oil production platform. While initial attempts predominantly targeted single genes, recent combinatorial metabolic engineering strategies have focused on the simultaneous optimization of oil synthesis, packaging and degradation pathways (i.e., ‘push, pull, package and protect’). This holistic approach has resulted in dramatic, seed-like TAG levels in vegetative tissues. With the first proof of concept hurdle addressed, new challenges and opportunities emerge, including engineering fatty acid profile, translation into agronomic crops, extraction, and downstream processing to deliver accessible and sustainable bioenergy.

Oxidant stimulation using Sodium Hypochlorite (NaClO) is proposed for enhancing coal seam permeability. To understand the effect of NaClO on different coal types, a subbituminous coal (Coal S) and a bituminous coal (Coal B) collected from the Surat Basin and Bowen Basin, Australia, respectively, were studied. The molecular structures of the two coals and their oxidised residues (Coal So and Coal Bo) were examined using Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR-FTIR), X-ray Photoelectron Spectroscopy (XPS) and solid state ¹³C Nuclear Magnetic Resonance Spectroscopy (¹³C NMR). Based on the results, the molecular structure schematic models of the samples were established. Results illustrate that Coal S is less aromatic with longer aliphatic chains and more oxygen content, while Coal B has larger average aromatic clusters, as expected given its higher rank. NaClO prefers to oxidise aliphatic chains, particularly those with oxygen functional groups. NaClO tends to oxidise small aromatic rings first, evidenced by the loss of smaller clusters in coal S, leaving the larger aromatic clusters. NaClO then attacks the larger aromatic clusters, confirmed by the average cluster size decrease for Coal B. The oxidised Coal B (Coal Bo) has a similar molecular structure to raw Coal S. After oxidation, both coal residues exhibit lower aromaticity, longer aliphatic chains and more oxygen content. The decreased aromaticity suggests reaction between NaClO and benzene rings. The breakage of aromatic rings is further suggested to give rise to longer aliphatic chains. NaClO oxidation products enriches the coals in C[dbnd]O and O-C=O for both coals. These findings observed fill a gap in knowledge on coal oxidation by NaClO and contribute to the decision of selecting the most suitable oxidant stimulation targets for enhancing coal permeability.

Emulgel is an emerging topical drug delivery system to which if more effort is paid towards its formulation & development with more number of topically effective drugs it will prove a boon for derma care & cosmetology. Emulgels are either emulsion of oil in water or water in oil type, which is gelled by mixing it with gelling agent. Incorporation of emulsion into gel increases its stability & makes it a dual control release system. Due to lack of excess oily bases & insoluble excipients, it shows better drug release as compared to other topical drug delivery system. Presence of gel phase makes it a non greasy & favors good patient compliance. These reviews gives knowledge about Emulgel including its properties, advantages, formulation considerations, and its recent advances in research field. All factors such as selection of gelling agent, oil agent, emulsifiers influencing the stability and efficacy of Emulgel are discussed. All justifications are described in accordance with the research work carried out by various scientists. These brief reviews on formulation method has been included. Current researched that work carried out on Emulgel are also discussed and highlighted the wide utility of Emulgel in topical drug delivery system. After the vast study, it can be concluded that the Emulgels appear better & effective drug delivery system as compared to other topical drug delivery system. The comprehensive analysis of rheological and release properties will provide an insight into the potential usage of Emulgel formulation as drug delivery system.

Primary fatty alcohols are found throughout the biological world, either in free form or in a combined state. They are common components of plant surface lipids (i.e. cutin, suberin, sporopollenin, and associated waxes) and their absence can significantly perturb these essential barriers. Fatty alcohols and/or derived compounds are also likely to have direct functions in plant biotic and abiotic interactions. An evolutionarily related set of alcohol-forming fatty acyl reductases (FARs) is present in all kingdoms of life. Plant microsomal and plastid-associated FAR enzymes have been characterized, acting on acyl-coenzymeA (acyl-CoA) or acyl-acyl carrier protein (acyl-ACP) substrates, respectively. FARs have distinct substrate specificities both with regard to chain length and chain saturation. Fatty alcohols and wax esters, which are a combination of fatty alcohol and fatty acid, have a variety of commercial applications. The expression of FARs with desired specificities in transgenic microbes or oilseed crops would provide a novel means of obtaining these valuable compounds. In the present review, we report on recent progress in characterizing plant FAR enzymes and in understanding the biological roles of primary fatty alcohols, as well as describe the biotechnological production and industrial uses of fatty alcohols.
