Abstract:
OBJECTIVE:To determine the contents of hydrochloric stachydrine in the shenning granule by TLC-scanning Method.METHODS:The acetone-dehydrated alcohol-HCl(10∶6∶1)were used as developing agents,the potassium hep-taiodobismuthate test solution-1%trichloride ferric dehydrated alchhol solution(2∶1)were used as the color-developing a-gents,the detection wavelength was530nm,the reference wavelength was670nm,the slit size was0.4mm?0.4mm,the lin-earization parameter Sx=3.RESULTS:The spot peak area score assumed a satisfactory linear relationship when the electric sample size for the hydrochloric stachydrine at a range of2.412?g～6.432?g(r=0.9972),the recovery was98.93%(RSD=1.15%).CONCLUSION:This method is simple,accurate,and this determination method has a good reproducibility,which can be used for the quality control of the shenning granule.
