Sažetak
The composition of the triacylglycerols is a characteristic of plant species and has nutritional, biochemical and technological importance. The oil from commercial soybean cultivars, corn and sunflower hybrids were extracted with diethilether contained buthyhidroxytoluene. The triacylglycerol compositions of oils were determined by reversed-phase high-performance liquid chromatography with refractive index detection. Triacylgylcerol were separated based on equivalent carbon numbers and were identified by comparing their retention time to standards. A total of 17 peaks were separated from injected oil sample and quantified based on relative percentage peak area. The main triacylglycerols (> 5%) in oils were trilinolein, dilinoleolein, dilinoleopalmitin, linoleodiolein, dilineostearin, linoleoleopalmitin and linolenodilinolein. The other minor triacylglycerols (< 5%) were linolenolinoleopalmitin, linoleodipalmitin, triolein, linoleoleostearin, dioleopalmitin, dioleostearin, dilinolenolinolein, dipalmitolein, trilinolenin, dilinolenolein and oleopalmitostearin. The main triacylglycerols represented in sunflower oil 88.14%, in corn oil 82.19% and in soybean oil 77.41% of total triacylglycerols. The differences between triacylglycerols composition within and between cultivars were calculated by analysis of variance. Significant differences (P<0.05) for individual triacylglycerols concentration in oil were found within and between soybean cultivars, corn and sunflower hybrids.
