目的:通过对淋结消中总大黄素的含量测定,为制定淋结消质量标准提供依据。方法:采用乙醇回流提取,盐酸水解30min,双波长薄层扫描法测定淋结消中总大黄素的含量。结果:平均回收率为98.29%,RSD=1.80%,n=5。结论:测定结果准确、稳定、灵敏度高、重视性好,本法可作为制定淋结消的质量标准参考。

OBJECTIVE:The determination of total emodin in Linjiexiao can provide basis for establishing its qualitative standard.METHDOS:Hot ethanol was used to extract,then hydrochloric acid was used to hydrolysate for 30minutes.The total emodinin Linjiexiao was determined by TLC scanning method.RESULTS:The average recovery was 98.29% with RSD=1.80%(n=5).CONCLUSION:The result was precise and stable.This method was sensitive and its repeatability was excellent.This method may serve as the reference to establishing the Linjiexiao.
