Abstract
Objective To establish the quality standard for Kangyuan Granula. Methods Radix Astragali, Radix Paeoniae Alba, Fructus Lycii and Radix et Rhizoma Glycyrrhizae in this prescription were identified by TLC. The content of the Paeoniflorin was determined by HPLC. The column of AichromBond-AQ-C18 (4.6 mm×150 mm, 5 μm) was used, the mobile phase was Water-Acetonitrile (85∶15), at the flow of 1.0 mL/min, the column temperature of 30 ℃, and peaks were detected at 230 nm. Results The characteristic of identification by TLC was distinct and highly specific. The linear range of Paeoniflorin was 0.0545~0.545 μg, r =0.999 5, the average recovery was 97.90%, RSD=1.06% (n =6). Conclusion The method was easy to operate with accurate result and good reproducibility. It can be used effectively for the quality control of this preparation.
