Therefore, it is of great significance to research on the qualification control of drug to ensure its safety and effectiveness. We have developed a quantitative method. HPLC was applied to determinate the two effective components in the chief herb-YC, with the liquid phase 0.025mol/L H3PO4(pH was adjusted to 3.0 with triethylamine)-methol-acetonitrile; the detection wavelength:345nm, the rate:1.0 ml/min and the column temperature:30℃. Results showed that the linear range of 6,7-dimedthoxycoumarin is 1.3-13ug/ml with the recovery of 96.62%; the linear range of 6-hydroxy-7-methoxycoumarin is 2.36-23.6ug/ml with the recovery of 96.50%. The analytical method is simple, sensitive and high reproducibility, thus provide qualitative and quantitative proof for the quality control of Capsule YBGY. 目 录
