In this present study, attempt was made to evaluate the pharmacodynamic properties of the different parts of E. hirta on those strains. The treatment of E. hirta extracts towards S. epidermidis and S. sonnei indicated the bactericidal activity in the kinetic study and significant PAE values on the treatment. Among E. hirta parts tested, whole plant extracts indicated fast killing effects via time-kill kinetics (kinetic study) for both strains. All the different parts of E. hirta extracts exhibited the significant PAE values (0.5 h and above) against strains tested. The kinetic study and PAE data basically indicated the stronger effect of E. hirta extracts toward S. epidermidis compared to S. sonnei.enEuphorbia hirta,pharmacodynamic properties,Staphylococcus epidermidis,Shigella sonnei,kinetic study,post antibiotic effects.Article15416434
