Octadecadienoic Acids

The seed oil of Tragopogonporrifolius L. was found to contain about 4% of conjugated diene hydroxy fatty acids, identified as 9-hydroxy-10,12- and 13-hydroxy-9,11-octadecadienoic acids. On dehydration, the products were 8,10,12- and 9,11,13-octadecatrienoic acids. The diene acids were cis,trans or trans,cis and the triene acids were judged to be all-trans.The conjugated triene acid of Calendulaofficinalis L. seed oil was isolated and identified as trans,8:trans, 10:cis,12-octadecatrienoic acid by spectral analysis, by the structure of the maleic anhydride adduct, and by identification of degradation products. All-trans-8,10,12-octadecatrienoic acid was found to react with maleic anhydride at both the 8,11 and 10,13 positions.

Major Acid

Seed oils were hydrolyzed under mild conditions and the major conjugated fatty acid of each oil was isolated and identified. In two families, species which were closely related botanically contained different but isomeric acids. Thus, in the Bignoniaceae, Jacaranda chelonia had cis trans,cis-8,10,12-octadecatrienoic acid as a major acid while Catalpa speciosa had trans,trans,cis-9,11,13-octadecatrienoic acid. In the Cucurbitaceae, Momordica charantia had the ordinary cis,trans,trans-9,11,13-octadecatrienoic (α-eleostearic) acid while M. balsamina had cis,trans,cis-9,11,13-octadecatrienoic (punicic) acid. M. balsamina is a new and convenient source of punicic acid. α-Eleostearic acid was identified as a major acid in examples of Valerianaceae and Rosaceae. Further proof was obtained that the fatty acid of Calendula officinalis (Compositae) is trans,trans,cis-8,10,12-octadecatrienoic acid.

The fatty oil of hare's-ear mustard seed (Conringia orientalis L.) was examined. Constants of the oil were determined and a partial separation of the fatty acids was carried out by the methyl ester fractionation method. Palmitic, oleic, linoleic, eicosenoic, erucic, and lignoceric acids were identified. Erucic acid was found to be present in largest amount. The oil resembles rapeseed and other Cruciferae seed oils in this respect. The content of eicosenoic acid is estimated to be not more than 12% of the total fatty acids.

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.

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.

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”.

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.
