Abstract: Objective To establish the quality control method for Sanhuang Suppository. Methods Coptidis rhizoma, Scutellariae radix and Phellodendri chinensis cortex in Sanhuang Suppository were identified by TLC. The contents of baicalin and berberine hydrocholride were determined by HPLC which was performed on an Agilent Zorbaxsb C18 column (4.6 mm×250 mm, 0.45 μm) with a mobile phase of methanol-water-phosphoric acid (47∶53∶0.2), with flow rate of 1.0 mL/min. The wavelength of detector was set at 280 nm for baicalin and 365 nm for berberine hydrochloride, with column temperature of 30℃.Results Chromatographic characteristics of qualitative identification were evident. The linear range of baicalin was 0.248-2.48 μg (r=0.999 9) and the average recovery rate was 99.77% (RSD=1.05%). The linear range of berberine hydrocholride was 0.336-1.68 μg (r=0.999 9) and the average recovery rate was 97.74% (RSD=1.48%).Conclusion The method of qualitative and quantitative analysis is accurate, feasible and suitable for effective quality control of Sanhuang Suppository.
