Title: Research on Quality Standard of Fuyanping Capsule
Abstract: Objective: To establish a method for differentiating Sophorae flavescentis radix, matrine, Cnidii frucrus, osthole and Picrasmae ramulus et folium by TLC and to detect the osthole in Fuyangping capsule by HPLC. Methods: The analysis was performed on TURNER Kromalil C18 column(200 mm×4.6 mm,5 μm) with acetontrile- water(65:35) as mobile phase and the detection wavelength was at 322 nm; TLC was used with positive and negative control to verify the constituents of Sophorae flavescentis radix, Picrasmae ramulus et folium and Cnidii frucrus, Osthole was detected in Fuyangping capsule by HPLC. Results: The osthole had a good linear relationship between 0.002 978 and 2.978 μg/mL, The average recoveries were 97.38% and the RSD was 2.1%(n=6). The content of osthole in Fuyangping capsule was 3.482 mg/g. Conclusion: This simple and rapid method with good separations can be used to control the quality of Fuyangping capsule.
