Abstract:
OBJECTIVE:To establish the quality criteria for Xiaoyan tablets. METHODS: Herba Taraxaci and Herba Violae in the formula were identified qualitatively by TLC and the content of Baicalin was determined by HPLC on Zorbax SB-C18(250 mm?4.6 mm,5 ?m) column with mobile phase consisted of acetonitrile-0.4%H3PO4(24∶76) at a flow rate of 1.0 mL?min-1. The detection wavelength was set at 280 nm and the column temperature was set at room temperature. RESULTS: Herba Taraxaci and Herba Violae could be detected by TLC. The linear range of Baicalin was 0.08～2.49 ?g(r=0.999 9). The average recovery rate was 100.24%(RSD=1.52%,n=6).CONCLUSION: The establish criteria are suitable for the quality control of Xiaoyan tablets.
