Abstract

AIM: To establish a new quality standard for Kangbindu Oral Solution (Radix Isatidis, Gypsum Fibrosum, Rhizoma Phragmitis, Radix Rehmannia, etc.). METHODS: Rhizoma Acori Tatarinowii and Fructus Forsythiae were identified by TLC. The forsythin content was determined by HPLC on Inertsil ODS column (4.6mm×250mm,5μm). The mobile phase was acetomitrile water(25∶75). The detection wavelength was set at 277nm. RESULTS: The linear range of forsythin was in the range of 4.24～21.2μg. The average recovery was 99.09%, and RSD was 0.4%( n =6). CONCLUSION: The method is simple and accurate, and can be used for the quality control of Kangbindu Oral Solution.
