Objective:To establish the quality standard for Qing'e Wan. Method: (+)-Pinoresinol di-O-β-D-glucopyranoside(PDG) was determined by HPLC. Result: The results of quantitative evaluation showed that (+)-pinoresinol di-O-β-D-glucopyranoside (PDG) concentration was linear in the range of 4.43-443 mg·L-1 (r=0.999 9)
the average recovery rate was 100.99% (RSD 2.17%). This method met the analysis requirement. Conclusion: The established quantitative methods were simple
accurate
reliable and reproducible
which can be effectively used for the quality control of Qing'e Wan.
