Abstract

Abstract:

Oil was obtained from seeds of Lindera thomsonii Allen by Soxhlet extraction method, and the yield of crude oil was 72.47%. After petroleum ether extraction, saponification and methyl esterification, total fatty acid methyl esters obtained were analyzed by GC-MS. In all, twenty peaks were separated and sixteen of them were identified, which accounted for 99.74% of total fatty acids. Most of the compounds were straight-chain fatty acids, of which, the percentages of n-decanoic acid and dodecanoic acid were 27.49% and 63.24%, respectively.

Key words: seed of Lingdera thomsonii Allen, fatty acid, GC-MS
