Liao Jian

Abstract

Objective:To determine the paeoniflorin content in qingguangkang tablets so as to establish a quality standard for qingguangkang tablets. Method:The content of paeoniflorin in the product was determined with HPLC method. Results:The linear range of paeoniflorin concentration was 0.104-0.520 μg·mL 1 and correlation coefficient was 0.999 3. The average recovery of sample was 98.00% with a RSD of 1.18%( n =6). Conclusion:The method is suitable for the quality control of qingguangkang tablets.
