【摘要】 目的：研究冬凌草叶中冬凌草甲、乙素的含量测定。方法：采用薄层扫描法进行测定。结果：冬凌草甲素浓度在９．５０μｇ～４７．５０μｇ之间线性关系良好，相关系数ｒ＝０．９９９，回收率为９８．５４％，测定的ＲＳＤ＝１．４１％。冬凌草乙素浓度在９．９８μｇ～４９．９０μｇ之间线性关系良好，相关系数ｒ＝０．９９９，回收率为９８．０７％，测定的ＲＳＤ＝１．３５％。结论：本法简便、准确、灵敏，重现性好，可用于冬凌草的质量控制。由本法测定结果表明，生长在济源太行山区８月份的冬凌草叶中冬凌草甲、乙素的含量最高更多还原

【Abstract】 OBJECTIVE: To study the method for quantitative determination of oridonin and ponicidin in the leaves of Rabdosia rubescens. METHODS: TLCS method was selected to determine the content. RESULTS: For oridonin the linear range was 9.50 μg～47.50 μg with r=0.999, the average recovery was 98.54% with RSD 1.41%. For ponicidin the linear range was 9.98 μg～49.90 μg with r=0.999, the average recovery was 98.07% with RSD 1.35%. CONCLUSION: The method was proved to be simple, precise sensitive and reproduciable. It can be used for the quality control of Rabdosia rubescens. The results showed that the content of oridonin and ponicidin in the leaves of Rabdosia rubescens, which grows in August in Ji Yuan county area, is relatively the highest.更多还原
