摘要
目的:摸索甘草中甘草酸的含量测定方法。方法:采用煎煮法进行提取,并用紫外分光光度法对甘草酸进行含量测定。结果:含量测定的加样回收率为96.4%,RSD 为2.07%。结论:含量测定简便可靠,可较好的控制质量。
Objective:To optimize glycyrrhizic acid's content determination.Methods:to ex- tract glycyrrhizic acid by decoction and determinate it's content by ultraviolet spectrophotometry. Results:The yield of diosgenin was about 10%;the recovery was 96.4% and the relative standard deviation was 2.07%.Conclusions:the method of determination is simple,accurate and repro- ducible.
