Objective:To establish a method for quality control of Biyanling Pill. Method: Cocklebur fruit
Flos magnoliae liliflorae
Mentha haplocalyx and Asarum were identified by TLC
and the content of baicalin in pills was determined by HPLC with C18 column and the mobile phase consisted of methanol-water-phosphoric acid solution (47∶53∶0.2). Detection wavelength was set at 278 nm. Result: Cocklebur fruit
Flos magnoliae liliflorae
Mentha haplocalyx and Asarum could be identified by TLC. The calibration curves of baicalin was in a good linearity in the range of 0.125 6-2.198 μg (r=0.999 9). The average recovery rate was 98.05% with RSD of 1.66% (n=6). Conclusion: The method is simple
accurate and can be applied to the quality control of Biyanling Pill.
