番荔枝籽油脂脂肪酸组成的GC-MS分析

摘要

Fatty acid composition of Annona squamosa L. Seed oil was studied in this paper. Oil of Annona squamosa L. Seed was extracted by Soxhlet extraction and fatty acid composition was analyzed by GC-MS. The yield of Annona squamosa L. Seed oil was 29. 2%. The GC-MS results showed that Annona squamosa L. Seed oil was composed of 8 kinds of fatty acids, maily oleic acid (45. 37%) , linoleic acid (30. 68%) , palmitic acid (13. 60%) ,stearic acid(8. 94%). And the content of unsaturated fatty acids was up to 76. 29%. Annona squamosa L. Seed was of good development and utilization value due to its high oil content,varieties of fatty acids,especially higher content of unsaturated fatty acids.%研究了番荔枝籽油脂中脂肪酸的组成.用索氏脂肪抽提器提取番荔枝籽的油脂,并以GC-MS分析油脂脂肪酸的组成.结果表明,番荔枝籽油脂收率达29.2％；番荔枝籽油脂中含有8种脂肪酸,主要为:油酸(45.37％)、亚油酸(30.68％)、棕榈酸(13.60％)和硬脂酸(8.94％),其中不饱和脂肪酸含量达76.29％.番荔枝籽含油量高,脂肪酸种类丰富,尤其是不饱和脂肪酸含量较高,具有较高的开发利用价值.
