ABSTRACT
AIM:
To establish the determination of baicalin and wogonin in Chantui Zhike Granules (Periostracum Cicadae, Radix Scutellariae, etc.) by HPLC.METHODS:
The determination was carried out by HPLC. The mobile phase was acetonitrile 0.6% phosphoric acid(45∶55) and UV detection wavelength was set at 275nm. The flow rate was 1.0mL?min -1 . The column temperature was at 40 ?C .RESULTS:
The contents of baicalin and wogonin in Chantui Zhike Granules could be determined by HPLC. There was a good linearity between the absorption peak area and the concentration in the range of 0.104?g~0.52?g for baicalin and in the range of 0.03?g~0.15?g for wogonin, respectively. The average recoveries were 100.69%( RSD =1.75%) and 98.8%( RSD =1.01%) respectively.CONCLUSION:
The method is simple, accurate and can be used to determine the contents of baicalin and wogonin in Chantui Zhike Granules.
