Title: Study on Quality Standard of Yinxieling Tablet
Abstract: [Objective] To establish the quality standard of Yinxieling tablet.[Method] The RADIX ARNEBIAE,FLOS SOPHORAE,FLOS LONICERAE JAPONICAE and RADIX ET RHIZOMA SALVIAE MILTIORRHIZAE were identified by TLC,and content of chlorogenic acid was determined by HPLC.[Result] Sample was clear in spot with no interference.When the concentration of chlorogenic acid ranged from 0.010 69 to 0.064 14 μg/ml,the relationship between concentration and peak area was good with correlation coefficient of 0.999 6.The recovery rate was 98.40% with RSD value of 1.43%(n=6),and mean content of chlorogenic acid in samples was 127.7 mg/g.[Conclusion] Simple in operation,good in stability,specificity and repeatability,the method established in this work was a favorable method for quality control of Yinxieling tablet.
