高效液相色谱法对黄柏炮制品的研究

Determination of Berberine in Processed Amur Corktree (Phellodendron amurense) by HPLC

利用高效液相色谱法对4种黄柏炮制品中盐酸小檗碱的含量进行了比较研究。结果表明，与生黄柏比较，盐黄柏和酒黄柏的盐酸小檗碱含量变化不大，而黄柏炭中小檗碱的含量损失殆尽。此方法的精密度和回收率均达到定量分析标准。

A HPLC method for the determination of berberine in Phellodendron amurense processed by four different procedures has been established. The method is simple, specific and accurate. The recovery is 102.7% and coefficient of variation is 0.69%.
