Oil and Triacylglycerols Composition of Soybean Lines

The composition of the triacylglycerols is a characteristic of plant species and has nutritional, biochemical and technological importance. Influence of year on oil content in grain and triacylglycerols composition of oil from soybean lines (Glycine max (L) Merrill) was investigated. The study was conducted in eastern Croatia and involved three sets of soybean genotypes depending of maturity group: 00, 0 and I over three years on an anthropogenic hypogley hydro meliorated soil. Oil content in grain was determined by near infrared transmittance spectroscopy. Triacylglycerols (TAG) were analyzed by reversed phase high performance liquid chromatography with refractive index detector and identified by comparing their retention time to standards. The results showed that oil content varied significantly among soybean lines within and between years. The main TAG components were trilinolein, dilinoleolein, dilinoleopalmitin, linoleodiolein, linoleoleopalmitin, linolenodilinolein and triolein represented in oil from soybean lines 84 %. Other minor TAG were linolenolinoleopalmitin, linoleodipalmitin, linoleoleostearin, dioleopalmitin, dioleostearin, dilinolenolinolein and dipalmitolein. A significant difference of triacylglycerol composition was noticed among soybean lines whereas larger one was noticed among the investigated years. In field selection, choosing lines with good quality traits can improve the nutritional and functional quality of the soybean oil.
