GC-MS法测定黄粉虫脂肪酸组成及含量的研究

ANALYSIS OF FATTY ACIDS IN TENEBRIO MOLITOR LINNEEUS BY GC-MS

采用超临界CO2萃取法对黄粉虫中的油脂进行提取,然后将油脂进行皂化、甲酯化,以毛细管色谱-质谱联用法(GC-MS)测定黄粉虫油脂中的脂肪酸组成,共鉴定出14种成分,主要含有亚油酸、棕榈酸、9-十六烯酸和肉豆蔻酸,其相对含量分别为35.88%,22.48%,8.07%和7.11%。

Fatty oil from Tenebrio molitor Linneeus was obtained by supercritical CO2 extraction. After saponification and cation the oil was determined by capillary GC-MS. 14 compounds were identified. The major components were linoleic acid, hexadecanoic acid, 9-hexadecenoic acid and tetradecanoate acid, and their relative contents were 35.88 %, 22.48 %, 8.07 % and 7.11%, respectively.
