摘要
黄芪对心血管系统作用的主要有效成分是黄芪皂甙,黄芪皂甙大部分是以环黄芪皂醇为甙元的皂甙,其中黄芪甲甙含量最高。本文以双波长薄层扫描λ_s=500nm,λ_R=700nm测定环黄芪醇皂甙和黄芪甲甙的含量。
The methods for TLC-densitometric determination of cycloastragenoside and astragaloside IV in radix astragali has been established. Samples were saponifed by methanol containing 2% potassium hydroxide and extracted with chloroform - n - butanol. Other samples were not saponifed and were directly extracted with chloroform - n - butanol. The spots were scanning with CS - 930 scaner (Shimadzu) at λs = 500nm and λR = 700nm for cycloastragenoside and astragaloside IV .The average recovery was 95.8%.
