Abstract
OBJECTIVE An HPLC method was developed for determination of dl-Tetrahydropamatine in Yan-husuo. METHOD:The column was ODS Agilent zobax Extend C18(4.6×250mm,5μm),mobile phase was Meth-anol-0.1%. phosphoric acid(adjust pH 6.0 with Triethylamine)(55:45). Detection wavelength was set at 280nm. RESULT:Linearity range was 115-1376ng. The average recovery was 99.2%, RSD=1.5%(n=6). CONCLUSION The method is accurate and can be used for quality control of Yanhusuo.
