摘要: 本文用索氏提取法提取荔枝种子中脂溶性成分,进行甲酯化处理后,采用气相色谱-质谱联用技术分离和鉴定其组成和含量,共鉴定出30种脂溶性成分,主要为油酸、亚油酸、棕榈酸、硬脂酸和2-辛基-环丙烷辛酸,相对含量分别为30.42%、11.77%、8.74%、4.94%和32.93%。荔枝核脂溶性成分具有较高的营养保健价值,值得进一步开发利用。

Abstract: Fat-soluble components in seed of Litchi chinensis were extracted by Soxlet extraction method.The fat-soluble components were esterified and then analyzed by gas chromatography-mass spectrometry.30 fat-soluble components were identified respectively.9-octadecenoic acid,9,12-octadecadienoic acid,hexadecanoic acid,octadecanoic acid and 2-octyl- cyclopropaneoctanoic acid are the chief components,and their relative contents are 30.42%,11.77%,8.74%,4.94% and 32.93% respectively.The fat-soluble components in seed of Litchi chinensis have high nutritional and healthy fuction,and further development and application potential.

Key words: seed of Litchi chinensis, fat-soluble components, GC-MS
