用GC-MS联用技术检测分析经甲酯化处理的新疆产水飞蓟精油中脂肪酸的组成及其相对含量,共检测出7种脂肪酸,其组成和相对含量分别为:棕榈酸10.53%,硬脂酸3.80%,山嵛酸0.74%,油酸45.42%,亚油酸36.33%,亚麻酸0.80%,花生酸1.07%。新疆产水飞蓟油的脂肪酸组成与文献报道的中国其他产地的水飞蓟油的脂肪酸组成基本相同,但水飞蓟油中各种脂肪酸的含量与文献报道的中国其他产地水飞蓟油的各种脂肪酸含量有显著的不同,亚油酸含量为所有文献中报道最低,油酸含量为所有文献中报道最高。新疆产水飞蓟油中总饱和脂肪酸:总单不饱和脂肪酸:总多不饱和脂肪酸的比值为1∶3∶2.5,是一种天然营养均衡植物油。
The composition and relative content of fatty acids in methyl salicylic acid treated with methyl esterification were detected by GC-MS. Seven kinds of fatty acids were detected, the contents of which were 10.53% of palmitic acid, Stearic acid 3.80%, behenic acid 0.74%, oleic acid 45.42%, linoleic acid 36.33%, linolenic acid 0.80% and arachidic acid 1.07%. The fatty acid composition of Xinjiang artemisiin oil is basically the same as the fatty acid composition of silybum marianum reported in the literature of other places in China, but the contents of various fatty acids in silybum marianum oil are similar to those reported in the literature of China There was a significant difference in the contents of various fatty acids, the linoleic acid content was the lowest reported in all the literature and the oleic acid content was the highest reported in all the literature. The total saturated fatty acid in the total amount of monounsaturated fatty acids: total polyunsaturated fatty acids in Xinjiang is 1: 3: 2.5, which is a kind of natural nutrition balanced vegetable oil.
