Abstract:
OBJECTIVE:To establish an HPLC method for the determination of the contents of Decussatin,Bellidifodin,Methylswertianin and Swerchirin in Swertia macrosperma C.B.Clark.METHODS:The determination was performed on VP-ODS C18(150 mm? 4.60 mm,5 ? m),with the mobile phase consisting of methanol-water-phosphoric acid(70∶ 30∶ 0.4),the detection wavelength set at 254 nm,the flow rate at 1.0 mL? min-1 and the column temperature at 20℃.RESULTS:The calibration curves of Decussating,Bellidifodin,Methylswertianin and Swerchirin were in good linearity in the range of 0.172～ 0.86 ? g,0.224～ 1.344 ? g,0.144～ 0.72 ? g and 0.154～ 0.77? g,respectively.The average recoveries were 98.18%(RSD=1.19%),99.32%(1.52%),98.44%(1.23%)and 97.68%(1.57%),respectively.CONCLUSION:The method is rapid and precise,with accurate and reliable results.
