摘要:Gas chromatography with mass spectrometry was used for performing a qualitative analysis of liposoluble flour extract made of different types of small grains (bread wheat, barley and triticale). The results show that the dominant methyl-esters of fatty acids composition is same for all samples, but the percentage of their representation in various types of small grains is different. Transesterification reagent was TMSH (Trimethylsulfonium hydroxide, 0.2M in methanol). With transesterification reaction fatty acids from acilglycerol esterifyed to methyl-esters. In all extract analyzed methyl linoleate predominated, followed by methyl palmitate, methyl oleate and methyl stearate in decreasing order. The following tests cluster analysis was used for the comparison of the liposoluble flour extract different types of small grains.
