超临界CO_2萃取灵芝孢子油的GC/MS分析

GC/MS Analysis of Ganoderma Lucidum Spores Oil Extracted by Supercritical CO_2

采用超临界CO_2萃取破壁灵芝孢子,萃取条件22MPa,40℃,将所得的孢子油,经GC/MS定性和定量分析,共检出18种脂肪酸成分,其中亚油酸和油酸占62.45％,不饱和脂肪酸占68.42％。

Ganoderma Lucidum Spores was extracted by Supercritical C02. The extraction condition was 22 MPa( extraction pressure), 401 ( extraction temperature) , 8 MPa( separator pressure) , 501 ( separator temperature). Then the spores oil was analyzed with GC/MS. The results show that the fatty acid composition is oleic acid, linoleic acid, stearic acid, palmitic acid, a few tridecanoic acid, pentadecanoic acid, heptadecanoic acid and so on, the unsaturated fatty acid content is 68.42%, and the content of oleic acid and linoleic acid is 62.45% .
