摘要
目的 建立复方金蒲片中延胡索乙素含量测定方法。方法 采用紫外分光光度法 ,检测波长为λ =2 81nm。结果 延胡索乙素线性范围 16 μg～ 4 0 μg ,线性方程A =0 .0 16 0C +0 .0 176 ,r=0 .9995 ,平均回收率 96 .6 4 % ,RSD =1.81%。 结论 紫外分光光度法测定延胡索乙素含量可用于复方金蒲片质量控制。
Objective To find a better method to determine the content of dl-tetrahydropalmatine of the new medicine.Methods The content of dl-tetrahydropalmatine was determined by ultraviolet spectrophotometry, with wavelength of 281nm.Results The average recovery of dl-tetrahydropalmatine was 95.8%, The linear range was 16μg ～ 40μg.Conclusion The method is rapid, accurate, and suitable for the quality control.
