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.

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.

In the course of our investigations of new sources of higher plant lipids, seed fatty acid compositions and the tocochromanol contents of Salvia bracteata, S. euphratica var. euphratica, S. aucherii var. canascens, S. cryptantha, S. staminea, S. limbata, S. virgata, S. hypargeia, S. halophylla, S. syriaca and S. cilicica were investigated using GLC and HPLC systems. Some of the species are endemic to Turkey. All the Salvia sp. showed the same pattern of fatty acids. Linoleic, linolenic and oleic acid were found as the abundant components. Tocochromanol derivatives of the seed oil showed differences between Salvia species. γ-Tocopherol was the abundant component in most of the seed oils except of S. cilicica. The total tocopherol contents of the seed oils were determined to be more than the total of tocotrienols.

Hibiscus Esculentus

The fatty acids of okra seed oil (Hibiscusesculentus L.) were examined. Acetylation of the oil, followed by saponification and separation of the acids, gave 12,13-dihydroxyoleic acid. From this and other evidence it is concluded that 12,13-epoxyoleic acid is present as a constituent of the glycerides. An oxygenated acid has not been identified previously in seed oils of this plant family (Malvaceae). 9-Hexadecenoic acid was also found. The total fatty acid composition was determined by distillation of the methyl esters and analysis of the distilled fractions. The percentages of the acids identified were estimated as follows: 9-hexadecenoic 0.6, palmitic 29, linoleic 39, oleic 23, stearic 2, 12,13-epoxyoleic 3, arachidic <1. Myristic, eicosenoic, and trienoic acids were not detected and, if present, are judged to have been in amounts less than 1% of the total.

Palado (Aglaia sp) is a plant that grows wild in the forest around Mamuju regency of West Sulawesi, Indonesia. This plant is locally known as palado. Palado seeds (Aglaia sp) can be used as a source of vegetable oil because it contains approximately 14.75 % oil, and it has the potential to be used as food ingredients or as raw material for oil production. The purpose of this study was to determine the chemical properties and the composition of fatty acids contained in palado seed oil (Aglaia sp). The employed method involved the use of palado fruit that had been processed to be palado seed and undergoing flouring process. Palado flour was produced by the extraction process by using chloroform solvent with the soxhlet method. The characteristics of the chemical properties in the oil produced were analyzed by using a standard method, including iodine, saponification, and acid values. The analysis of fatty acid composition was conducted by using gas chromatography. The results showed that palado oil extracted with hexane had an iodine value of 15.38 mg/g, saponification value of 190.01 mg KOH/g, and acids value of 1.961 mg KOH/g. The fatty acid composition of the palado seed oil consisted of saturated fatty acids (41.601 %), which included palmitic acid (41.062 %), myristic acid (0.539 %), and unsaturated fatty acids (45.949 %), which included mono-unsaturated fatty acids (MUFA) such as (22.929 %), oleic acid and poly-unsaturated fatty acids (PUFA), which was linoleic acid (23.020 %).

Cold-pressed seed oil from twelve commercially produced cactus pear cultivars was assessed for oil yield, fatty acid composition, physicochemical properties, quality and stability. Large differences in oil content, fatty acid composition and physicochemical properties (IV, PV, RI, tocopherols, ORAC, % FFA, OSI and induction time) were observed. Oil content ranged between 2.51% and 5.96% (Meyers and American Giant). The important fatty acids detected were C16:0, C18:0, C18:1c9 and C18:2c9,12, with C18:2c9,12, the dominating fatty acid, ranging from 58.56-65.73%, followed by C18:1c9, ranging between 13.18-16.07%, C16:0, which ranged between 10.97 - 15.07% and C18:0, which ranged between 2.62-3.18%. Other fatty acids such as C14:0, C16:1c9, C17:0, C17:1c10, C20:0, C18:3c9,12,15 and C20:3c8,11,14 were detected in small amounts. The quality parameters of the oils were strongly influenced by oil content, fatty acid composition and physicochemical properties. Oil content, PV, % FFA, RI, IV, tocopherols, ORAC and ρ-anisidine value were negatively correlated with OSI. C18:0; C18:1c9; C18:2c9,12; MUFA; PUFA; n-6 and PUFA/SFA were also negatively correlated with OSI. Among all the cultivars, American Giant was identified as the paramount cultivar with good quality traits (oil content and oxidative stability).

The aim of the study was to examine the effect of dietary supplementation of isomerized poppy seed oil (IPO) enriched with conjugated dienes of linoleic acid (CLA) on cow and sheep milk parameters (fat content, fatty acid profile, Δ9-desaturase index, and atherogenic index). The process of poppy seed oil alkaline isomerization caused the formation of CLA isomers with cis-9,trans-11, trans-10,cis-12, and cis-11,trans-13 configurations in the amounts of 31.2%, 27.6%, and 4.1% of total fatty acids (FAs), respectively. Animal experiments were conducted on 16 Polish Holstein Friesian cows (control (CTRL) and experimental (EXP), n = 8/group) and 20 East Friesian Sheep (CTRL and EXP, n = 10/group). For four weeks, animals from EXP groups received the addition of IPO in the amount of 1% of dry matter. Milk was collected three times: on days 7, 14, and 30. Diet supplementation with IPO decrease milk fat content (p < 0.01). Milk fat from EXP groups had higher levels of polyunsaturated fatty acids, including FAs with beneficial biological properties, that is, CLA and TVA (p < 0.01), and lower levels of saturated fatty acids, particularly short- (p < 0.01) and medium-chain FAs (p < 0.05). The addition of IPO led to a decrease in the atherogenic index.

B16f10 Cells

Melanogenesis is a complex process that can lead to pigmentation defects. Various chemical skin-lightening products have been developed to treat pigmentation disorders. However, these chemical products can cause harmful adverse effects. Therefore, the development of safer, natural bleaching ingredients is a trend for sustainability. It has been reported that unsaturated fatty acids exhibit significant antimelanogenic effects. Sapindus mukorossi seed oils contain abundant unsaturated fatty acids; however, these have not yet been investigated for beneficial effects on skin tone evenness. In this study, we tested the possibility of using S. mukorossi oil for the treatment of hyperpigmentation in an in vitro model. Free fatty acid compositions and β-sitosterol were determined by gas chromatography-mass spectrometry and high-pressure liquid chromatography, respectively. The effect of S. mukorossi oil on melanoma B16F10 cell viability was detected using the 3-(4,5-dimethylthiazol-2-yl)- 2,5-diphenyl-tetrazolium bromide assay. The inhibitive effects of fatty acids and β-sitosterol in S. mukorossi oil on α-melanocyte-stimulating hormone (MSH)-induced melanogenesis was evaluated by detecting melanin formation and tyrosinase activity. Our results showed that S. mukorossi oil produced no significant cytotoxicity in B16F10 cells at various concentrations compared with the control group. The enhancement of melanin formation induced by α-MSH was reduced by S. mukorossi oil. We also found that the primary fatty acid contributing to the antimelanogenesis effect was eicosenoic acid. These results suggest that S. mukorossi seed oil can effectively inhibit melanogenesis and has the potential for future development as a de-hyperpigmentation product within a waste utilization context.
