摘要: 本实验采用超临界萃取法萃取锁阳中的脂溶性成分,并用GCMS对其脂溶性成分进行分析。通过正交实验获得最优的萃取工艺条件,即萃取压力30 MPa,萃取温度45 ℃,CO2流量12 mL/min,萃取时间2.5 h。锁阳的脂溶性成分经柱色层族分离后得到非极性、弱极性、极性三种馏分,经GCMS共鉴定出101种化合物,其中非极性馏分21种,弱极性馏分40种,极性馏分40种。在锁阳的脂溶性成分中,脂肪酸类成分占绝对优势,其含量占检出成分总量的90.595%;其次,酯类和正构烷烃分别占5.069%和1.088%;其余成分仅占3.248%。所检出成分中以反式油酸、亚油酸、正十六烷酸和11二十烯酸含量最高为特征,其相对含量均大于5%。

Abstract: In this study,the liposoluble constituents of Cynomorium songaricum was extracted by supercritical fluid extraction(SFE)and analyzed by GCMS.The optimal extraction conditions were obtained by orthogonal experiment,namely the extraction pressure 30 MPa,extraction temperature 45 ℃,CO2 flow rate 12 mL/min,extraction time 2.5 h.The liposoluble constituents were separated into three parts that conclude nonpolar fraction,weak polar fraction and polar fraction by column chromatography.A total of 101 compounds were identified which the number of that three parts are 21,40 and 40,respectively.In the liposoluble constituents of C.songaricum,fatty acids are the highest components and their relative content reached 90.595%.Esters and alkanes accounted for 5.069% and 1.088%,respectively.The remaining components accounted for only 3.248%.The content of(E)9octadecenoic acid,9.12octadecadienoic acid,hexadecanoic acid and 11eicosenoic acid were the highest,and their relative contents of all were more than 5%.
