Abstract:
Objective:To develop an HPLC gradient elution method for the simultaneous determination of fangchinoline,tetrandrine,mesaconitine,aconitine and hypaconitine in Huoxue Zhentong plaster.Methods::A Dikma-C18 (200 mm×4.6 mm,5 μm) chromatographic column was adopted,the mobile phase was methanol-acetonitrile (3∶1)(A)-0.06% diaethylamin solution (B) with gradient elution at a flow rate of 1.0 ml·min-1,the detection wavelength was 280 nm for fangchinoline and tetrandrine,and 235 nm for mesaconitine,aconitine and hypaconitine.The column temperature was set at 30 ℃,and the injection volume was 10 μl.Results::There was a good linear relationship when the content of fangchinoline,tetrandrine,mesaconitine,aconitine and hypaconitine was within the range of 7.490-149.800 μg·ml-1(r=0.999 9),14.610-292.200 μg·ml-1(r=0.999 8),4.150-83.000 μg·ml-1(r=0.999 2),5.250-105.000 μg·ml-1(r=0.999 6) and 5.140-102.800 μg·ml-1(r=0.999 9),respectively.The average recovery and the corresponding RSD were 99.87%(0.49%),97.79%(1.11%),96.97%(1.75%),98.60%(1.50%) and 97.94%(0.98%)(n=6),respectively.Conclusion:An HPLC gradient elution method is successfully established for the simultaneous determination of 5 components in Huoxue Zhentong plaster.The established method is simple,accurate and reliable,which is helpful to the quality control of Huoxue Zhentong plaster.
