gave higher yield of chemical constituents expected for this research work;
the originality of this work is that good results have been found with hydroalcohol ratio, and it will be helpful to carry out other data with MIC and other formulation study, because in comparison of methanol or water extracts, hydroalcohol is more suitable for clinical study.
The hydroalcoholic extracts of Cassia fistula were found to be active on most of the clinically isolated microorganism and fungi, as compare with standard drugs. The present study justified the claimed uses of leaves in the traditional system of medicine to treat various infectious disease caused by the microbes. However, further studies are needed to better evaluate the potential effectiveness of the crude extracts as the antimicrobial agents. The present results will form the basis for selection of plant species for further investigation in the potential discovery of new natural bioactive compounds. Further studies which aimed at the isolation and structure elucidation of antibacterial active constituents from the plant have been initiated.
