桑叶中脂肪酸的GC-MS分析

用正己烷提取桑叶中的脂肪酸，经皂化、酯交换法处理后，气相色谱-质谱(GC-MS)联用分析和鉴定脂肪酸的化学成分。结果是，共分离出24种化合物，鉴定了其中的19种脂肪酸，占脂肪酸总含量的93．18％。桑叶中脂肪酸的成分以棕榈酸(26．87％)、亚麻酸(22．99％)、亚油酸(13．40％)、硬脂酸(6．99％)、油酸(3．17％)、花生酸(3．43％)、棕榈油酸(3．05％)、山萮酸(2．93％)、蜡酸(1．63％)等为主。

Analysis of Fatty Acids in Mulberry Leaves by GC-MS

Mulberry leaves were extracted with n hexane,and the extractive was saponified and esterfied The chemical components of fatty acids were separated and identified by GC MS 24 fatty acids were separated and 19 fatty acids of them were identified,and their relative contents were 93 18% The main components of the fatty acids in mulberry leaves were palmitic acid(26 87%),linolenic acid(22 99%),linoleic acid(13 40%),stearic acid(6 99%),oleic acid(3 17%),arachidic acid(3 43%),palmitoleic acid(3 05%),behenic acid(2 93%),cerotic acid(1 63%)
