马齿苋及其籽中脂肪酸的比较研究

Comparative Study of Fatty Acids in Portulaca Oleracea L. and Its Seeds

本实验利用ＧＣ－ＭＳ分析技术对马齿苋全草及其籽中的脂肪酸（以甲酯的形式）进行了分析，共鉴定出８种脂肪酸。全草中以亚麻酸（４７．１６％）、亚油酸（２２．００％）及棕榈酸（１７．４％）为主，籽中以亚油酸（４５．８６％）及亚麻酸（３０．６１％）为主。

Fatty acids in Portulaca oleracea L.and its seeds were analysed by capillary GC-MS.Eight fatty acids were found,main constituents in the whole weed were linolenic acid(47.16%),linoleic acid(22.00%)and plamilic acid(17.46%),and in the seeds were linoleic acid (45.86%)and linolenic acid(30.61%).
