Croton megalobotrys and Ricinus cummunis plants produce high-quality non-edible seed oils at relatively high quantities of 39.65 ± 0.06 % w/w to 53.74 ± 0.04 % w/w. The Iodine values of 85.97 ± 1.62 g I2/100 g to 96.51 ± 1.31 g I2/100 g; the low acid values of 0.96 ± 0.05 mg KOH/g to 5.31 ± 0.76 mg KOH/g; and high saponification values of 139.65 ± 1.06 mg KOH/g to 153.01 ± 1.67 mg KOH/g show that these seed oils can be useful feedstocks in the petroleum, soap, and cosmetics industries. GC-MS results revealed that R. cummunis seed oil is made up of eight (8) fatty acids with the bulk being ricinoleic acid at 81.51 %. Ricinoleic acid is the main fatty acid used in oleochemical industries. C. megalobotrys seed oil is made up of five (5) fatty acids, the most abundant being Linoleic acid which makes up 58.01 % of the seed oil. The other two significant fatty acids in C. megalobotrys seed oil are palmitic and oleic acids at 19.51 % and 18.37 %, respectively. These acids are important as starting materials in soap, cosmetic, and pharmaceutical industries. The fatty acids of the two seed oils absorb light at the ultraviolet region of the electromagnetic spectrum. This means that cosmetic products made from these seed oils will be effective in protecting the human skin against ultraviolet radiation. The FT-IR peaks for the two seed oils show that even though these seed oils are made up of different fatty acids, the active sites of their fatty acids are similar, implying that these seed oils can be used as starting materials in similar industries.

First Time

Tree peonies (Paeonia ostii and Paeonia rockii) are popular ornamental plants. Moreover, these plants have become oil crops in recent years. However, there are limited compositional studies focused on fatty acids. Therefore, this work aims to reveal compositional characteristics, regarding fatty acids, sterols, γ-tocopherol and phenolic compounds, of tree peony seed oils from all major cultivation areas in China, and to compare with herbaceous peony seed oil. For that, an integrative analysis was performed by GC-FID, GC-MS and UHPLC-Q-TOF-MS technologies. The main fatty acid was α-linolenic acid (39.0–48.3%), while β-sitosterol (1802.5–2793.7 mg/kg) and fucosterol (682.2–1225.1 mg/kg) were the dominant phytosterols. Importantly, 34 phenolic compounds, including paeonol and “Paeonia glycosides” (36.62–103.17 μg/g), were characterized in vegetable oils for the first time. Conclusively, this work gives new insights into the phytochemical composition of peony seed oil and reveals the presence of bioactive compounds, including “Paeonia glycosides”.

Natural Remedies

All parts of A. indica (neem) and R. communis (castor) plants have mostly been used as natural remedies in the control and treatment of several ailments, control of pests and insects, animal feeds and production of industrial products globally. The seed oils of A. indica and R. communis are known to have antidiabetic, anti-helminthic, antifertility, antioxidant, antibacterial, anti-inflammatory, anti-cancer, insecticidal and mosquitocidal activity. This study reports for the first time the chemical composition of A. indica and R. communis seed oils from Marigat, Baringo County, Kenya. Seed oils of A. indica and R. communis were   extracted from mature dried seeds through cold pressing and boiling respectively and chemical composition determined using Gas Chromatography (GC)-Mass Spectrometry (MS).  The constituents of both seed oils were dominated by saturated and unsaturated fatty acids, cyclic esters and methyl esters. The predominant constituents of R. communis were (Z)-6-Octadecenoic acid (37.33%), Ricinoleic acid (30.22%) and 13-Hexyloxacyclotridec-10-en-2-one (26.67%) while those of A. indica were 2-hexyl-1-decanol (30.97%), Octadecanoic acid (29.69%) and Oxalic acid, 6-ethyloct-3-yl ethyl ester (15.55%). Oils contained Hexadecanoic acid and Octadecanoic acid which are used in the manufacture of several products such as candles, soaps, lotions, perfumes and cosmetics. Octadecenoic acid is important in control of human diseases and Ricinoleic acid in production of alkyd resins for surface coating and biofuel.  From the results, A. indica and R. communis seed oils constituents have potential in the agricultural, industrial, comestics and pharmaceutical sectors but require further fractionation to isolate the bioactive compounds.

Important Medicinal Plant

Aloe ferox is an important medicinal plant in Southern Africa whose seeds could be useful as a source of oil. The fatty acid composition of A. ferox seed oil was determined using gas chromatography. The physicochemical properties of the oil were analysed using standard methods. The seeds yielded 19.4% of a light textured oil using the Blight and Dyer's method and 12.3% using the Soxhlet extraction method. The saponification value of the seed oil was 241.9 mg KOH/g and the peroxide value was 8.9 meq/kg. The acid value of the seed oil was 51.5 mg KOH/g (25.9% free fatty acids). The major fatty acids found in the seed oil were linoleic acid (71.8%), oleic acid (12.0%), palmitic acid (11.2%) and stearic acid (2.9%). The results obtained suggest that as A. ferox seed oil is high in linoleic acid, it could be potentially exploited in the cosmetic and pharmaceutical industries.

The Impact

Wild Paeonia ludlowii is considered as a traditional ornamental plant, but its flowers and seed oils are edible with important economic values, and the variation of nutrients, fatty acid composition in wild populations is scarcely known. Flowers and seeds of P. ludlowii were collected from two wild populations for evaluating the nutrients in flowers, composition of fatty acids in seed oils and the antioxidant activity. The flowers contained high composition of proteins, carbohydrates, amino acids, total flavonoids, phenolic compounds and essential minerals. Seed oil yield reached up to 21.95% using supercritical CO2 fluid extraction, and it contained 14 fatty acids (up to 93.35 g/100g seed oil), especially the unsaturated fatty acids (oleic acid, linoleic acid and α-linolenic acid) was up to 88.69% with low ω6/ω3 ratios of 0.58. The antioxidant capacity can be arranged in the order of trolox > flower extracts > seed oil according to the DPPH and ABTS free radical assay. Contents of nutrient in flowers and fatty acids in seed oils were significantly different between two wild populations due to the impact of different growing environments. These results indicate that flowers and seed oils of P. ludlowii are potential food resources in human diets.

Cotton (Gossypium L.) is one of the most important commercial crops and it is famous as white gold. Cotton has a diversity of applications, principally medicinal and many other usages, such as pigments, derivatives for cattle feed, different uses of the oil extracts and etc. Cottonseed oil has a ration of 2:1 of polyunsaturated to saturated fatty acids and generally consists of 65-70% unsaturated fatty acids, including 18-24% monounsaturated (oleic) and 42-52% polyunsaturated (linoleic), and 26-35% saturated (palmitic and stearic). The most important health benefits of cotton is treat respiratory diseases, treat skin problems, treat wounds, beneficial for breastfeeding mothers, a good cure for rat bite, an appropriate cure for scorpion bite, for joint and eye pains, for swollen legs, for removing bacteria in teeth, and alternative medicine for various diseases such as cancer, HIV and etc. Cotton seed oil mostly extracted from Gossypium hirsutum and Gossypium herbaceum, that are also grown for cotton fiber and animal feed. Gossypol is one of the most effective ingredients, both in traditional pharmaceutical practices and alternative modern medicinal preparations. It is a toxic polyphenolic bisesquiterpene, which may have antifertility and antiviral properties. The obtained findings suggest potential of cotton as a natural resource in pharmaceutical industries.

The fatty acid composition of date seed oil from two different date palm ( Phoenix dactylifera L.) cultivars, locally known as Degla-Baïdha and Tafezouine, were investigated. GC analysis revealed the presence of five dominant fatty acids: oleic C18:1 (46.51; 39.15%), lauric C12:0 (22.1; 28.5%), myristic C14:0 (10.7; 11.4%), palmitic C16:0 (9.6; 8.7%) and linoleic C18:2 (6.9; 6.1%). The oils was characterised by a low content of tocopherols (0.53; 1.41 μg/g). The antioxidant activity of the oils was investigated using the DPPH•(1,1-di-phenyl-2-picryl-hydrazyl) scavenging assay. The oils had a weak bleaching effect on DPPH• free radicals. This study showed that the qualities of the tested oils are highly comparable with those of some commercial seed oils of other plants. Furthermore, a statistical analysis using the hierarchy ascendant classification method was conducted in order to highlight the similarities and/or the differences regarding the contents of the main fatty acids found in some common plants and in the five most famous cultivars of Phoenix dactylifera of south eastern Algeria (Tafezouine, Degla-Baïdha, Deglet-Nour, Ghars, Tamdjouhert).

Tea Seed Oil

Physicochemical properties, fatty acid composition, antioxidant compounds and oxidative stability of oil-tea seed oil (Camellia oleifera Abel.) and green-tea seed oil (Camellia sinensis O. Ktze.) were investigated. The refractive index, saponification value, iodine value, acid value, peroxide value, unsaponifiables were determined to assess the quality of the oils. The major fatty acids of green-tea seed oil and oil-tea seed oil were oleic acid, linoleic acid and palmitic acid. Green-tea seed oil was typical oleic-linoleic-oil with 52.13% oleic acid and 24.32% linoleic acid level, whereas oil-tea seed oil was typical oleic-oil with very high oleic acid level (73.67%). The amount of total phenols, α-tocopherol and β-carotene of green-tea seed oil were 8.68 mg/kg, 160.33 mg/kg, 3.20 mg/kg, respectively, whereas they were 17.90 mg/kg, 85.66 mg/kg, 1.18 mg/kg in oil-tea seed oil, respectively. Green-tea seed oil contained high amounts of α-tocopherol which was nearly twice that of oil-tea seed oil. The initial induction period (IP) values of green-tea seed oil and oil-tea seed oil were 6.55h and 6.08h at 110 oC by OSI method, respectively, which shows the oxidative stability of two kinds of tea seed oils were preferable. Therefore, oil-tea seed oil could be a good dietary supplement with high level of monounsaturated fatty acids and similar fatty acid composition of olive oil. Green-tea seed oil was a new oil resource which is rich in α-tocopherol in China.
