Hemolytic activity of methanolic extracts of flowers from Delonix regia (DrFME), Cassia fistula (CfFME), and Lagerstroemia speciosa (LsFME). (A) The percent hemolysis showed by the extracts at different concentrations. (B) Half-maximal inhibitory concentration (IC50) of DrFME, CfFME and LsFME obtained by non-linear regression analysis at a 95% confidence interval.
