摘要:

采用化学法萃取和GC-MS 法,对从国内5 个省、市、自治区收集的紫苏属植物5 个变种的10 份试材种子的含油率及其脂肪酸组分进行研究。结果表明,紫苏属植物10 份试材间种子的含油率介于33.49%~42.58% 之间;应用SPSS 11.0 软件对其种子含油率进行单因素方差分析,表明紫苏属植物5 个变种10 份试材间种子含油率存在极显著性差异。GC-MS 分析结果表明,紫苏属植物种子油中脂肪酸的组成简单,10 份试材种子油中共检测出6 种脂肪酸组分——棕榈酸、亚油酸、α- 亚麻酸、硬脂酸、10- 十八碳烯酸和油酸,其中前4 种为10 种试材的共有成分,1、2、3、5 号试材含油酸,但不含10- 十八碳烯酸,4、6~10 号试材含有10- 十八碳烯酸,但不含油酸。10 份试材种子油中α- 亚麻酸含量介于71.75%~80.06% 之间,不饱和脂肪酸的含量介于88.80%~92.82% 之间。

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%.

Key words: the genus Perilla, seeds oil, fatty acids, gas chromatography-mass spectrometry (GC-MS)
