紫草籽油的超临界CO_2萃取及其脂肪酸含量分析_戴震安 . Supercritical-CO_2 fluid extraction and fatty acid contents analysis of lithospermum seeds oil

Abstract

The lithospermum seeds oil was extracted by supercritical CO 2 and the total fatty acids of the oil were analyzed by capillary column gas chromatography. In the fatty acids, the saturated and unsaturated fatty acids are 7.9% and 91.3% respectively. The content of α-linolenic acid and γ-linolenic acid are 30.2% and 13.8% respectively.
