紫苏种子油成分自然变异的研究

对山西省内12份野生紫苏种子含油量及脂肪酸的组成成分进行了测定分析,结果表明,各样品的含油量介于30.83%～32.76%之间,样品间没有明显差异;通过气相色谱法测定分析,紫苏籽油中脂肪酸由软脂酸、硬脂酸、油酸、亚油酸、亚麻酸、花生酸、花生烯酸等组成,不饱和脂肪酸含量约占脂肪酸总量的90%以上,其中亚麻酸含量介于57.8%～62.1%之间,油酸含量介于20.2%～23.6%之间。表明紫苏籽油是一种极具开发潜力的营养保健油。

Natural Variation for Seed Oil Composition in Perilla frutescens

In this paper,we analyzed the natural variation in Perilla frutescens.Twelve accessions from different regions in Shanxi province were surveyed for content of oil and fatty acid composition in their seeds.The results showed that：the oil content of the samples ranged from 30.83%～32.76% of seed dry weight,no significant difference between samples.Through comparison and analysis of fatty acid component of different accessions through GC method,we found that：the fatty acid components in perilla seed oil included palmitic acid,stearic acid,oleic acid,linoleic acid,linolenic acid,arachic acid,aracholeic acid etc.;according to the GC analysis,their polyunsaturated fatty acids reached as high as about 90%,and the linolenic acid content ranged from 57.8%～ 62.1%,oleic acid content ranged from 20.2%～23.6%.It showed that perilla seed oil was a new resource for development of the nutrition and health oil.
