Abstract

Plan:  Antibacterial activity of leaves and seed of Pongamia pinnata and Lawsonia innermis have been studied for their antimicrobial activities using agar well diffusion method.

Methodology: The selected bacterial strains, namely Bacillus subtilis, Escherichia coli,Enterobacter aerogenes, Micrococcus luteus and Pseudomonas aeroginosa isolated from PSG Hospital, Coimbatore, Tamilnadu were selected for the study. Maximum zone of inhibition of the active compounds was evaluated by using NCCLS Method.The plant extracts were tested with the standard positive control chloramphenicol.

Outcome: Among the three solvents analysed ethanolic leaf extract of Pongamia pinnata and Lowsonia innermis exhibited a maximum resistance against Bacillus subtilus and possessed a highest inhibitory zone against Pseudomonas aeroginosa and Micrococcus luteus respectively when compared to other bacterial strains.

Keywords: Pongamia pinnata, Lawsonia innermis antibacterial activity, plant extracts, agar well diffusion method.
