ABSTRACT
Objective To determine the content of tripterine in Tripterygium wilfordii and its tablets by HPLC.Methods An external standard method by HPLC with Zorbax C_(18)column as fixed phase and methanol-1% HAc(87∶13) as mobile phase was adopted.The detection wavelength was 425 nm and the flow rate was 1.0 mL/min.Results The linear range for tripterine was 40.96~204.8 ?g/mL(r=(0.999 6).) The average recovery of Chinese medicinal materials was 98.37% and RSD was 1.01%(n=9);the average recovery of preparation sample was 98.59% and RSD was 1.18%(n=9).Conclusion The method is simple and accurate,which can be adoptable for quantitative analysis of tripterine in the plants of Tripterygium L.
