| Abstract: | Objective： To establish the determination method of berberine hydrochloride in Shanxiaodan capsules. Method： The methanol as solvent, berberin hydrochloride in Shanxiaodan capsule was extracted by ultrasonic method. UV spectrophotometry was selected to determine the content, and the detection of wavelength was 348nm. Result： The Absorbance has a linear relationship with the berberin hydrochloride within the range of 2.24 - 15.68 μg·ml^-1. The average recovery was 99.8% RSD 0. 6%. Conclusion： The method is simple, accurate, and repeatable. It can be for the assay of berberin hydrochloride in the preparation. |
