紫苏属植物种子含油率及其脂肪酸组成_胡彦 . Oil Contents and Fatty Acid Composition of the Seeds of the Genus Perilla from Different Geographical Origins

Abstract

Soxhlet extraction was used to extract seed oils from 10 plant samples (from different areas of China) belonging to 5 varieties of the genus Perilla,followed by the fatty acid composition analysis using GC-MS.The oil contents of these 10 Perilla seed samples ranged from 33.49% to 42.58%.The one-way analysis of variance achieved using software package SPSS 11.0 showed that there was a significant difference in oil content among these 10 Perilla seed samples.The GC-MS analysis indicated that these 10 Perilla seed samples exhibited simple fatty acid composition.Palmitic acid,linoleic acid,α-linolenic acid and stearic acid were found in all of these 10 Perilla seed samples.Oleic acid was found only in Perilla seed samples No.1,2,3 and 5 and 10-octadecenoic acid only in Perilla seed samples No.4 and 6-10.The relative contents of α-linotenic acid of these 10 Perilla seed samples ranged from 71.75% to 80.06% and the content of unsaturated fatty acids from 88.80% to 92.82%.
