| Abstract:Objective:To establish a quantitative analysis method for berberine hydrochloride and total alkaloids in compound Er-xian decoction. Methods: Berberine hydrochloride were determined by HPLC. Using Hypersil-BDS C18 (4.6 x 200 mm) column, methanol-0.02 mol/L sodium dihydrogen phosphate-0.1 mol/L triethylamine (40-60-2) as the mobile phase. The detection wavelength was 345 nm. Total alkaloids were determined at 420 nm by visible spectrometry. Results: The linearity range of berberine hydrochloride was 0.51～10.10 μg/mL, r=0.999 9, and average recovery was 100.07%,RSD 0.4%. The linearity range of total alkaloids was 8.0～24.0 μg/mL, r=0.999 8, and average recovery was 100.46%, RSD 0.58%. Conclusions: The method is simple, quick and accurate.It can be used to control the quality of the decoction preparation. |
