RESUMO
Objective: To establish a method for determination of tetrahydropalmatine in Anwei tablets. Methods: tetrahydropalmatine in Anwei Tablets was extracted by chloroform and determined by dual wavelength TLC scanning (? s=275nm,? R=340nm).Results: The average recovery was 95%.17%, RSD was 2.50% (n=5). The contents of tetrahydropalmatine in three batches were 7.45,7.17 and 7.90?g/tablet, respectively.Conclusions: The method is stable and feasible.
