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.

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.

Abstract The red sunflower seed weevil, Smicronyx fulvus L., is a univoltine seed-feeding pest of cultivated sunflower, Helianthus annuus L. Artificial infestations of S. fulvus onto sunflowers with traditional (<25% oleic acid), mid-oleic (55–75%), or high oleic (>80%) fatty acid profiles were used to test if fatty acids could be used as natural markers to estimate the proportion of weevils developing on oilseed sunflowers rather than wild Helianthus spp. and confection (non-oil) types. Oleic acid (%) in S. fulvus confirmed the fatty acid compositions of mature larvae and weevil adults reflected their diets, making primary (oleic or linoleic) fatty acids feasible as natural markers for this crop-insect combination. Oleic acid in wild S. fulvus populations in North Dakota suggests at least 84 and 90% of adults originated from mid-oleic or high oleic sunflower hybrids in 2017 and 2018, respectively. Surveys in 2017 (n = 156 fields) and 2019 (n = 120 fields) extended information provided by S. fulvus fatty acid data; no significant spatial patterns of S. fulvus damage were detected in samples, damage to oilseed sunflowers was greater than confection (non-oil) types, and the majority of damage occurred in ≈10% of surveyed fields. Combined, data suggest a few unmanaged or mismanaged oilseed sunflower fields are responsible for producing most S. fulvus in an area. Improved management seems possible with a combination of grower education and expanded use of non-insecticidal tactics, including cultural practices and S. fulvus-resistant hybrids.

Seed oils have been used for centuries by communities as food, medicine, cosmetic applications, and fuel. Recently, there has been a renewed interest in these nontimber forest products specifically for use in cosmetic formulations. The fatty acid compositions of kernel oil of Heynea trijuga was analyzed by GC-FID. The results showed that the oil content was 37.61 percent (w/w) in seed. Seed oil was rich in unsaturated fatty acids. Important fatty acids present were palmitic acid (22.12%), stearic acid (7.51%), oleic acid (25.20%), and linoleic acid (11.65%).

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.

Watermelon Seed

Seed oil percentage (SOP) and fatty acid composition of watermelon (Citrullus lanatus) seeds are important traits in Africa, the Middle East, and Asia where the seeds provide a significant source of nutrition and income. Oil yield from watermelon seed exceeds 50% (w/w) and is high in unsaturated fatty acids, a profile comparable to that of sunflower (Helianthus annuus) and soybean (Glycine max) oil. As a result of novel non-food uses of plant-derived oils, there is an increasing need for more sources of vegetable oil. To improve the nutritive value of watermelon seed and position watermelon as a potential oil crop, it is critical to understand the genetic factors associated with SOP and fatty acid composition. Although the fatty acid composition of watermelon seed is well documented, the underlying genetic basis has not yet been studied. Therefore, the current study aimed to elucidate the quality of watermelon seed oil and identify genomic regions and candidate genes associated with fatty acid composition. Seed from an F2 population developed from a cross between an egusi type (PI 560023), known for its high SOP, and Strain II (PI 279261) was phenotyped for palmitic acid (16:0), stearic acid (18:0), oleic acid (18:1), and linoleic acid (18:2). Significant (P < 0.05) correlations were found between palmitic and oleic acid (0.24), palmitic and linoleic acid (–0.37), stearic and linoleic acid (–0.21), and oleic and linoleic acid (–0.92). A total of eight quantitative trait loci (QTL) were associated with fatty acid composition with a QTL for oleic and linoleic acid colocalizing on chromosome (Chr) 6. Eighty genes involved in fatty biosynthesis including those modulating the ratio of saturated and unsaturated fatty acids were identified from the functionally annotated genes on the watermelon draft genome. Several fatty acid biosynthesis genes were found within and in close proximity to the QTL identified in this study. A gene (Cla013264) homolog to fatty acid elongase (FAE) was found within the 1.5-likelihood-odds (LOD) interval of the QTL for palmitic acid (R2 = 7.6%) on Chr 2, whereas Cla008157, a homolog to omega-3-fatty acid desaturase and Cla008263, a homolog to FAE, were identified within the 1.5-LOD interval of the QTL for palmitic acid (R2 = 24.7%) on Chr 3. In addition, the QTL for palmitic acid on Chr 3 was located ≈0.60 Mbp from Cla002633, a gene homolog to fatty acyl- [acyl carrier protein (ACP)] thioesterase B. A gene (Cla009335) homolog to ACP was found within the flanking markers of the QTL for oleic acid (R2 = 17.9%) and linoleic acid (R2 = 21.5%) on Chr 6, whereas Cla010780, a gene homolog to acyl-ACP desaturase was located within the QTL for stearic acid (R2 = 10.2%) on Chr 7. On Chr 8, another gene (Cla013862) homolog to acyl-ACP desaturase was found within the 1.5-LOD interval of the QTL for oleic acid (R2 = 13.5%). The genes identified in this study are possible candidates for the development of functional markers for application in marker-assisted selection for fatty acid composition in watermelon seed. To the best of our knowledge, this is the first study that aimed to elucidate genetic control of the fatty acid composition of watermelon seed.

This paper reports the physicochemical characteristics of the seed oils from different varieties of passion fruit (Passiflora alata Curtis, Passiflora edulis f. flavicarpa and Passiflora quadrangularis) cultivated in Brazil, Roraima. The oil  from passion fruit, within the range of 19.29±0.02; 21.34±0.22 e 14.24±0.16%, respectively. The physicohemical characteristics of the extracted oils were: free fatty acid contents (0.84±0.01 - 2.73±0.05 % mg KOH g-1 as oleic acid), iodine value (101.63±0.18 - 125.96±0.13 g of I2 100 g-1 of oil), and saponification index (90.56±0.32 - 179.06±0.19 mg KOH g-1 of oil). The oils revealed a reasonable oxidative parameter range as depicted by the determinations of index peroxide value (1.92±0.09 – 3.05±0.03 meqO2 kg-1 of oil). Linoleic acid was the major fatty acid found in all the seed oils with contributions of 55.75-63.42% of the total fatty acids (FA). Other fatty acids detected were known to be oleic acid (19.3-20.1%), palmitic acid (10.8-12.8%) and stearic acid (3.25-4.25%). Through the DPPH test we observed the presence of antioxidants in the three oil samples. The results of the present study indicate that the seeds of the tested passion fruit varieties from Roraima are a potential source of high-linoleic oil and thus can be explored for commercial use and value addition.

Fatty Acid Compositions

The fatty acid compositions of the total, neutral, and polar lipids of Blastocladiella emersonii have been determined. Major fatty acids were palmitic, oleic, linoleic, γ-linolenic, and arachidonic acid. Polar lipid contained a higher proportion of linoleic, γ-linolenic, and arachidonic acid than did neutral or total lipids, whilst neutral lipid had a high proportion of palmitic and oleic acid. In addition to γ-linolenic acid, α-linolenic acid was also present; this is the first occasion that both isomers have been demonstrated in the same fungus, and the phylogenetic possibilities of this finding are discussed.

The fatty acid compositions of the oil from 6 varieties of rapeseed grown at 22 stations were determined by gas liquid phase chromatography. Significant differences were found between stations for all fatty acids and between varieties for palmitic, stearic, oleic, linoleic, eicosenoic and erucic acids. The variations for palmitic, stearic, and eicosenoic acids were small, whereas major variations occurred in oleic, erucic and linoleic acids. A correlation coefficient of −0.975 was found between oleic and erucic acids and a prediction equation was determined to calculate oleic acid from the erucic acid content.
