摘要
用超临界ＣＯ２流体萃取技术从紫苏子中萃取脂肪油，经常法皂化和甲酯化后，用ＧＣ－ＭＳ－计算机联用技术从中分离鉴定了α－亚麻酸等１２个脂肪酸成分，占总脂肪酸的９９．９１％。棕榈油酸等８个成分系首次从该植物中分得。与传统的石油醚萃取法相比，其萃取时间短，得油率高。主要有效成分α－亚麻酸的含量达７３．５％，约提高４％。
Fatty oils from the seeds of Perilla frutescens were extracted by supercritical-CO2 or petroleum ether. After saponification and esterification these acidesters were analyzed by GC-MS. The results showed that the fatty acids from SFE-CO2 contain α-linolenic acid (73.5%) and other 11 components (99.91% of total fatty acids), 8 constituents of them were first obtained from the plant. The yield of the fatty oils from SFE-CO2 was higher than that from petroleum ether extraction.
