ABSTRACT
AIM:
A methond was established for the determination of emodin and chrysophanol in Zhenhuang Powder (Margarita, Radix et Rhizoma Rhei, artificial Calculus Bovis, etc.).METHODS:
RP HPLC was used for samples separated on a shim pack VP ODS column with the mobile phase of methanol-0.1% H 3PO 4(85∶15) and the detection wavelength was set at 430nm.RESULTS:
The calibration curves were linear in the range of 0.01181~4.724?g( r =0.9994) for emodin and in the range of 0.01300~5.200?g( r =0.9999) for chrysophanol, respectively. The average recoveries were 99.0%( RSD =1.23%, n =5) and 100.5% ( RSD =1.06%, n =5), respectively.CONCLUSION:
The method is simple, realizable and reproducible. It can be used effectively for the quality control of Zhenhuang Powder.
