    Abstract:
    OBJECTIVE: To establish methods for the determination of phillyrin and forsythoside A in Lianqiao Bingdu Qing capsule by RP-HPLC. METHOD: The determination of phillyrin was carried out on YWG-C18 column (4.6 mm x 250 mm, 10 microm), using acetonitrile-water (25:75) as mobile phase at a flow rate of 0.8 mL x min(-1) and detected at the wavelength 277 nm. The determination of forsythoside A was carried out with YWG-C18 column(4.6 mm x 250 mm,10 microm), using acetonitrile-water-Acetic acid (17:83:0.4) as mobile phase at a flow rate of 1.0 mL x min(-1) and detected at the wavelength 280 nm. RESULT: The average recovery of phillyrin was 99.6%, RSD = 1.9% (n = 5). The average recovery of forsythoside A was 101.3%, RSD = 2.5% ( n = 5). CONCLUSION: The methods were simple and accurate and could be used to control the quality of the Lianqiao Bingdu Qing capsule.
