用超临界CO_2流体萃取技术从紫苏子中萃取分离出脂肪油,常法甲酯化后,用GC-MS—计算机联用技术对其进行了研究,从中分离鉴定了12个成分,占总脂肪油的99.91％,其中α-亚麻酸为主要成分,占73.46％。棕榈油酸(palmitoleic acid)等8个成分系首次从该植物中分离到。药理毒理证明,该脂肪油具有很好的调血脂作用,无毒副作用。 Supercritical CO2 fluid extraction technology was used to extract and separate fat oil from Perilla frutescens. After routine methyl esterification, GC-MS-Computer was used to study the fat oil. Twelve components were separated and identified from the oil, accounting for total fatty oil. Of the 99.91%, α-linolenic acid was the main component, accounting for 73.46%. Eight components such as palmitoleic acid were isolated from the plant for the first time. Pharmacology and toxicology proved that the fatty oil has a good lipid regulating effect and has no toxic or side effects.
