Establishment of the QAMS method for the determination of rutin， linarin，luteolin and apigenin in Herba Cirsii / 国际药学研究杂志

ABSTRACT

Objective: To establish a method for the quantitative analysis of multi-components by single marker (QAMS)to determine the content of rutin,linarin,luteolin and apigenin in Herba Cirsii. Methods: Rutin was selected as the internal reference substance,the relative correction factors(RCF)of the other 3 components were established re- spectively,and then the content of each component was calculated according to respective RCF. At the same time,the external standard method was used to determine the content of all four components in Herba Cirsii,the differences be- tween calculated values and measured values were compared,and the method validation was performed. Results: No significant difference was observed between the calculated values and measured ones according to the results from ten batches of Herba Cirsii samples. Conclusion: The validated QAMS method is proved to be of good precision,reproduc- ibility,and reliability which is suitable and feasible for the quality control of Herba Cirsii
