【摘要】 用超临界CO₂流体萃取技术从当归（Angclica sinensis）中萃取分离出挥发油,并用GC-MS-计算机联用技术对其进行了研究,从中分离鉴定了38个成分,并进行了含量测定。亚油酸、藁木内酯、棕榈酸为其主要成分,其含量分别为56.74％、19.82％及14.20％。其中乙酸（acetic acid）等28个成分为首次从该植物中分离到。更多还原

【Abstract】 Essential oils from Angelica sinensis were extracted by supercritical-CO2 fluid and the oils were analyzed by GC-MS. The restult showed that the oils from CO2-SFE contain 38 components, linoleic acid, ligustilide and palmitoleic acid of them are the major constitutents whose content are 56.74%, 19.82% and 14.20% respectively.28 constituents of them are first obtained from the plant.更多还原
