摘要:

采用氯仿甲醇(CM)法提取荔枝果肉中的脂肪酸,经甲酯化处理用气相色谱- 质谱联用仪进行分析。结果分离鉴定出16 种脂肪酸,其主要化学成分为不饱和脂肪酸;含量最高的成分为油酸(44.405%),其次为棕榈酸(25.144%),再次为亚油酸(18.905%);其中直链饱和脂肪酸(SFA)为28.44%,单不饱和脂肪酸(MUFA)为52.46%,多不饱和脂肪酸(PUFA)为19.11%。

Abstract:

A GC-MS method was developed for the fatty acid composition analysis of litchi pulp. Fatty acids were extracted from litchi pulp using a mixture of chloroform and methanol (2:1, V/V) and esterfied with methanol prior to GC-MS. A total of 16 fatty acids were isolated and identified, and most of them were unsaturated fatty acids, especially the content of 9-octadecenoic acid was the highest (44.405% of total fatty acids) followed by hexadecanoic acid (25.144%) and 9,12-octadecadienoic acid (18.905%). On the whole, straight-chain saturation fatty acids (SFA) accounted for 28.44%, monounsaturated fatty acids (MUFA) 52.46% and polyunsaturated fatty acids (PUFA) 19.11%.

Key words: litchi pulp, fatty acid, GC-MS
