Objective: To establish the determination method of tetrandrine content in Mappianthus iodoides. Method: VP-ODS Cl8 (4.6 mm×250 mm
5 μm) colmnn was used
the mobile phase was acetonitrile-0.3% triethanolamine (with H3PO4 to adjust pH 2.0) (45: 55)
the flow rate was 1.0 mL·min-1. The detection wavelength was sest at 280 nm. Result: The linear relation of hyperin was good in the range from 0.040 4 to 0.363 6 μg. The average recovery was 99.02%
RSD was 1.67%. Conclusion: The method established is accurate
sensitive and good in reproducibility. It can be applied to the quality control of Mappianthus iodoides.
