Analysis of Fat-soluble Components in Litchi chinensis Seeds by GC-MS

Abstract

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
