Abstract
OBJECTIVE To determine berberine hydrochoride in Zhongweikan capsules without separation. METHODS The absorption data was measured by the UV-VIS spectrophotometer, the convolution spectrometry method was used to calculate the concentration of berberine hydrochoride after absorption data transformation. RESULTS The average recovery and RSD of berberine hydrocholoride were as follows; 100.00% 0.03%. CONCLUSION Convolution spectrometry is reliable, accurate and suitable for the determination of the drug contents in hospital preparations.
