摘要(Abstract):

目的:建立一测多评法同时测定丹参中丹参酮ⅡA、丹参酮I、二氢丹参酮I、隐丹参酮的含量,验证该方法在丹参药材中应用的准确性和可行性。方法:以丹参药材为研究对象,药材中4个有效成分为指标性成分,分别建立丹参酮ⅡA与二氢丹参酮I、隐丹参酮、丹参酮I的相对校正因子,计算二氢丹参酮I、隐丹参酮、丹参酮I的含量,实现一测多评。同时采用外标法测定药材中4个指标性成分的含量,比较计算值与实测值的差异,以验证一测多评法的准确性和可行性。结果:16批丹参中4个指标性成分,采用校正因子计算的含量值与外标法实测值之间无显著差异。结论:在对照品缺乏的情况下,以外标法测定丹参酮ⅡA,利用相对校正因子实现对二氢丹参酮I、隐丹参酮、丹参酮I的含量测定是可行的,一测多评法可以用于丹参中多种成分的质量评价研究。
Objective: To establish a new method and validate its feasibilities for quality evaluation of Salvia miltiorrhiza.Method: Four main effective components,dihydrotanshinone I,cryptotanshinone,tanshinone Ⅰ and tanshinone ⅡA,were selected as analytes to evaluate the quality of S.miltiorrhiza.The relative correction factors(RCF) of tanshinone ⅡA to the other three tanshinones were calculated.The method was evaluated by comparison of the quantitative results between external standard method and QAMS method.Result: No significant differences were found in the quantitative results of four tanshinones by external standard method and QAMS method.Conclusion: It is a convenient and accurate method to determine multi-components when some authentic standard substances were unavailable.It can be used to control the quality of S.miltiorrhiza.
