目的:比较黄连与其余药材混煎及分煎合并两种工艺对舒胃颗粒中黄连生物碱含量的影响。方法:以黄连生物碱提取量为考察指标,采用紫外分光光度法测定黄连生物碱含量,对两种水提取方法进行比较。结果:按黄连药材投量计,混煎、分煎合并和黄连单煎所得3个样品中生物碱含量以盐酸小檗碱计,分别为3.88%,6.47%,8.37%。结论:分煎合并工艺中黄连生物碱损失量明显少于混煎工艺。
OBJECTIVE: To compare the effects of Coptidis Rhizoma with other herbs on the content of alkaloids in Shuwei Granules. Methods: The content of alkaloids extracted from Coptis chinensis was used as the inspection index. The content of alkaloids was determined by ultraviolet spectrophotometry. The two methods of water extraction were compared. Results: According to the dosage of Rhizoma Coptidis, the contents of alkaloids in the three samples obtained by mixed decoction, decoction combined, and Coptidis decoction were berberine hydrochloride, which were 3.88%, 6.47%, and 8.37%, respectively. Conclusion: The loss of Coptis alkaloids in the frying and splitting process is significantly less than that of the frying process.
