It was concluded that 60 kg N ha −1 with supplemental K application should be advised for enhancement in seed yield oil yield and N and K contents in seeds of black cumin without significant changes in fatty acid composition

Yield and its main components were positively affected by irrigation and by the earlier sowing date With regard to fatty acid composition a decrease in oleic and stearic acid and an increase in linoleic and palmitic acid were observed under irrigation At early sowing oleic and palmitic acid decreased whereas linoleic and stearic acid increased

Oil Content and Fatty Acid Composition in Seeds of Three

Seeds of six safflower (C tinctorius L ) genotypes and 19 accessions of two wild species were analyzed for oil and fatty acid composition Oil content ranged from 29 20 to 34 00 20 04 to 30 80 and 15 30 to 20 80% in C tinctorius C oxyacantha Bieb and C lanatus L respectively The main fatty acids of oleic linoleic palmitic and stearic acids composed 96–99% of the total fatty acids

The fatty acid composition of major oilseeds in comparison to the model plant Arabidopsis thaliana indicates that the seed oil triacylglycerol is dominated by the five main membrane fatty acids with some exceptions (Table 3) However the relative distribution of fatty acids in seed oils varies widely among plant species

2 2 EVALUATION OF OIL COMPOSITION 2 2 1 Fatty acid composition Fatty acid composition (FA) of the oils was determined by modified acid-catalysed esterification and trans esterification of free fatty acids and glycerides respectively using Method Ce 1-62 of AOCS (1991) Approximately 80 mg of oil was dissolved in 1 mL of petroleum ether

Comparison of fatty acid profile changes between unroasted and roasted brown sesame (Sesamum indicum L ) seeds oil The mean oil yields for unroasted and roasted seeds were 45 7 and 51 1 g respectively (Table 1) determine any changes in the oil composition between unroasted and roasted sesame we may The)

Further quality of oil was deteriorated due to increases in erucic acid polyunsaturated fatty acid and ω-6 fatty acid contents and reductions in oleic acid and nervonic acid contents due to sUV-B exposure Cultivar Vardan showed more negative impact on seed yield due to UV-B stress whereas quality of seed and oil was more affected in Sanjukta

Seed oil was determined by preparation of FAMEs followed by GC For percentage composition seed samples of 150–200 μg were weighed and extracted by incubation in 1 ml of 2 5% (v/v) sulfuric acid in methanol for 90 min at 80 C FAMEs were partitioned into hexane after addition of

Variability of seed oil content and fatty acid composition
