Introduction: to validate the flavonoid quantification method on Passiflora incarnata L. tablets by using quercetine as standard. Methods: selectivity, linearity, accuracy, precision and robustness were evaluated, using USP 30 and the regulations of the Center for the State Control of Drug Quality (CECMED). Results: under the conditions of this study, the method is selective, linear in a range of 60 to 140 % of flavonoid concentration. It showed accuracy and precision with global relative standard deviation of 0.67 %. The results did not significantly vary when the analytical conditions changed. Conclusions: under the established conditions, this method is reliable and allows obtaining appropriate results for the intended use.
