Phytochemical Screening and Antibacterial Activity of Mimosa pudica L. and Mimosa invisa L. Against Selected Microbes

The antibacterial activity of Mimosa pudica and Mimosa invisa were evaluated. The extract of these plants was obtained by using methanol and water as solvents. Antibacterial activity was screened by using agar well diffusion method against pathogenic bacteria, i.e., Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas fluorescens. M. pudica and M. invisa showed highest antibacterial activity against K. pneumoniae and B. subtilis respectively. Phytochemical screening revealed that M. pudica and M. invisa, in general, contain active constituents like alkaloids, tannins, flavanoids, steroids, phenols, glycosides, terpenoids, anthraquinones, etc. having a definite specificity.
