In Vitro antimicrobial activity using ethanolic extract of flower and stem extract of Cassia auriculata linn.

The present study involves evaluating the invitro antimicrobial activity using ethanolic extract of flower and stem extract of Cassia auriculata linn. The ethanolic extract of both flower and stem extract of Cassia auriculata was found to possess antimicrobial activity against strains of two Gram negative organisms Pseudomonas aeruginosa, Escherichia coli and two Gram positive organisms Staphylococcus aureus, Bacillus subtilis and one fungal pathogen (Candida albicans). The antimicrobial activity of the flower and stem extracts of Cassia auriculata Linn. were evaluated by disc diffusion method and Minimum Inhibitory Concentration assay. The results obtained in the study indicates that the flower and stem extract using ethanol can be a potential source of antimicrobial agents.
