用HPLC法测定4种不同工艺制备的黄连解毒汤提取物粉末及2种日本汉方颗粒剂黄连解毒汤中的小檗碱和巴马汀含量。结果表明此方法简便、快速、精密度高、回收率较好。采用此法比较了上述6种黄连解毒汤的生物碱含量。结果是新工艺制备的提取物中生物碱含量最高,其中小檗碱含量分别是东洋、津村黄连解毒汤的6倍和13.8倍,是传统水煎提取物的3倍。

[Abstract]
Contents of berberine and palmatine in four powdery preparations from “ Antidotal Decoction of Compounded Coptis” and two granular Japanese Kampo “Oren-gedoku-to” were determinated by HPLC.Results showed that powdery preparation obtained by the new production process showed a higher content of the two alkaloids than the two Japanese Kampo 6~13.8times and about 3 times of the products obtained from the traditional water decoction process.The HPLC determination was shown to be simple,rapid,with high precision and satisfactory recovery.
