【摘要】 采用微波加热吹气吸附法从孜然芹籽中提取孜然芹精油,萃取率4.45%。对采用气-质联机对所得精油的挥发性成分进行分析,共鉴定出34种物质,总相对含量为95.14%,主要成分为枯茗醛(27.05%)、枯茗醇(25.14%)、β-水芹烯(13.34%)、γ-松油烯(12.45%)、对伞花烃(12.27%)等。更多还原

【Abstract】 Essential oil of cumin seeds (Cuminum vyminum L.) was extracted by a microwave-heated purging and adsorption device in yield of 4.45%. The relative amounts of the components in GC-MS analysis were calculated by area normalization. Thirty- four compounds were identified,covering 95.14% of the total peak areas. The main volatiles were cuminyl aldehyde (27.05%),cumin alcohol (25.14%),β-phellandrene (13.34%),γ-terpinene (12.45%) and p-cymene (12.27%).更多还原
