Abstract:
Objective:To develop an HPLC wavelength switching method for the determination of seven components in Shenrong Guben tablets simultaneously.Methods:A Waters Sunfire C18column (250 mm ×4.6 mm,5 μm) was adopted. The column temperature was set at 30 ℃. The mobile phase was acetonitrile-0.1% phosphate solution with gradient elution. The flow rate was 0.9 ml·min-1. The detection wavelength were set at 330 nm for verbascoside and martinoside,230 nm for albiflorin and paeoniflorin,and 203 nm for ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1. Results:The linear range of verbascoside, martinoside,albiflorin, paeoniflorin, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1was 6.38-159.50 μg·ml-1(r =0.999 3),3.19-79.75 μg·ml-1(r =0.999 9),4.37-109.25 μg·ml-1(r =0.999 5),14.26-356.50 μg·ml-1(r =0.999 4), 1.95-48.75 μg·ml-1(r = 0.999 8), 2.21- 55.25 μg·ml-1(r = 0.999 7) and 2.09- 52.25 μg·ml-1(r = 0.999 1), respectively. The average recovery and the corresponding RSD was 98.24% (1.11%),97.64% (1.43%),99.23% (0.80%), 100.13% (0.65%),96.99% (1.56%),98.10% (1.24%) and 97.75%(1.37%),respectively. Conclusion:The developed method can determine the contents of verbascoside, martinoside, albiflorin, paeoniflorin, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1in Shenrong Guben tablets simultaneously,which can be applied in the quality control of Shenrong Guben tablets.
