This article studies crude fat, protein and cellulose content in ten different kinds of perilla seeds, and analyzes the fatty acids by GC method. The result shows that there are significant differences in nutrients among ten varieties,fat coentent range from 34. 0% to 45. 2% ,protein from 18. 5% to 21. 8% and cellulose from 19. 0% to 25.1%. The seed oils contain palmitic acid(0. 18% - 1.42% ) ,stearic acid(0. 32% - 1. 86% ) , oleie acid(11. 42% ~ 23.06%),linoleic acid (9. 97% - 13.02% ) and a - linolenic acid (58.48%-71. 23% . The unsaturated fatty acids account for 93- 32% -95. 43% in total fatty acids. ZS -5 and ZS -9 are screened as high - quality breeding materials for oil development and a - linolenic acid industrial extractions because of their higher content of crude fat and large proportion of a - linolenic acid.%本研究对10个不同品种紫苏种子粗脂肪、蛋白质和纤维素含量进行了测定,并对其脂肪酸组分进行了气相色谱分析.结果表明,10个不同品种紫苏种子粗脂肪、粗蛋白和纤维素含量存在显著差异,变化幅度为粗脂肪34.0％ ～45.2％,粗蛋白18.5％～21.8％,纤维素19.0％～25.1％.紫苏总脂肪酸中,棕榈酸占0.18％～1.42％,硬脂酸占0.32％ ～ 1.86％,油酸占11.42％～23.06％,亚油酸占9.97％～ 13.02％,α-亚麻酸占58.48％～71.23％,不饱和脂肪酸占到总脂肪酸的93.32％～95.43％.ZS -5和ZS -9两个品种粗脂肪含量高,α-亚麻酸比例大,是榨油和α-亚麻酸工业化分离提取的优良资源.
