Quantitative determination of berberine hydrochloride in shaoshang Ⅱ hao tincture by first derivative UV-spctrophotometry
Abstract: A first derivative UV-spectrophotometric method was successfully used without seperation for the determination of berberine in shaoshang Ⅱ hao tincture. The wavelength of determination was 361.3nm, the average recovery was 99.97%, RSD was 0.47% (n=5).The method is simple, rapid and accurate.
