紫斑牡丹种仁种皮中脂肪酸组成比较分析 . Comparative Analysis of Fatty Acid Composition in Seed Kernel and Coat of Paeonia rockii Seeds

Abstract

The shimadzu 2010 gas chromatograph,DB-WAX capillary column and supelco 37 fatty acid methyl ester mixture standard(37 FAME) were used to characterize the fatty acid composition in seed kernel and coat of P.rockii seeds.The results showed that the DB-WAX capillary colum could separate the most components of 37 FAME and were sufficient to determine fatty acid composition of most plants lipid;the composition of fatty acid in seed kernel and coat were similar,mainly palmitic,stearic,oleic,linoleic and linolenic acid;the content of linolenic acid was markedly high and in seed kernel the α-and γ-Linolenic acid were 31.56% and 7.32%,respectively.
