摘要
用紫外分光光度法测定盐酸黄连素片（BH）的含量，以343nm作为测定波长，BH浓度在0～10μg／ml范围内，线性关系良好，r=0．9998（n=6），回归方程为y=0．063x-0．00048。平均回收率为99．3％，变异系数＜1．3％。
The UV spectrometry with the wavelength of 343nm was set up to determinate berber-ine liydrochloride tablet (BH). The result showed that the linear relatwt coefficient was r=0.9998(n=6) in BH range of 0-10μg/ml. The regression equaiton was y=0.063x-0. 00048. The mean rate of recovery was 99.3%, The coefficient of dispersion was less than 1.3%.
