摘要
目的:建立双波长薄层扫描法测定胃安康口服液中黄芪甲甙和延胡索乙素含量的方法。方法:用双波长薄层反射锯齿形扫描,SX=7,狭缝0.4mm ×0.4mm ,灵敏度:X1 ,扫描速度:12mm·min- 1。结果:两成分线性关系良好;6 次测定平均回收率:黄芪甲甙为97.6% , RSD为1.02% ,延胡索乙素为101.0% , RSD为1 .58% 。结论:本法可用于测定胃安康口服液中黄芪甲甙和延胡索乙素的含量。
AIM To establish a method using dual wavelength TLC-scannig for the determination of astragalus saponin 1 and corydalis B in Weiankang oral liquid.METHODS The determination was carried out with the reflection zigzag scanning,SX=7,slit=0.4mm×0.4mm,sensitivity:X1、scan speed:12mm·min -1 。RESULTS Satisfactory linearity and accuracy were obtained with the recoveries (n=6) as follows:astragalus saponin 1 was 97.6% (RSD=1.02%);corydalis B was 101.0% (RSD=1.58%).CONCLUSION The dual wavelength TLC scanning method may be used for the determination of astragalus saponin 1 and corydalis B in Weiankang oral liquid.
