摘要
目的:探讨黄连中总生物碱含量的测定方法。方法:采用酸性染料比色法测定黄连中总生物碱的含量。结果:盐酸小檗碱在4.176~16.68μg/ml范围内呈线性关系,相关系数为0.9997,平均加样回收率为100.1%,RSD为1.84%,测得黄连中总生物碱含量为0.1125 g/g。结论:本含量测定方法操作简单,灵敏度高,准确性好,重现性好,可用于测定黄连总生物碱的含量。
Objective:To determine the total alkaloids content of in Coptis chinensis. Method: Acidic dye colorimetry was used to determine the alkaloids in Coptis chinensis. Result: The concentration of berberine hydrochloride showed good linearity within the range of 4. 176 - 16.68 μg/ml, r = 0. 9997 ,the average recovery was 100.1%, RSD = 1.84% , the total alkaloids from Coptis chinensis were determined as 0.112 g/g. Conclusion: The established method is simple, highly sensitive, accurate and reproducible, which can be used for determination of the total alkaloids in Coptis chinensis.
