Abstract:
The present study was carried out to evaluate the antimicrobial
potential of ethanolic, diethyl ether, ethyl acetate and aqueous extracts
of aerial parts of Bacopa monnieri (L.). The antimicrobial activity
of ethanolic, diethyl ether, ethyl acetate tested for the Staphylococcus
aureus, Proteus vulgaris, Candida albicans and Aspergillus
niger. Diethyl ether extracts of Bacopa monnieri showed an
antibacterial activity against gram positive and ethyl acetate extract
was active against gram negative organism. The extract of diethyl ether
having potent antimicrobial activity against Staphylococcus aureus
at higher concentrations (300 μg mL-1). Ethanolic extract
of Bacopa monnieri has more antifungal activity against Candida
albicans and Aspergillus niger. Diethyl ether extract and Ethyl
acetate extract has slight antifungal activity but have broad spectrum
of antibacterial effect against the entire tested organisms, whereas ethanolic
extract showed marked inhibitory activity against fungal species. Aqueous
extract of the different concentration showed no inhibitory effects on
the tested microorganisms due to loss of some active compounds during
extraction processes of the sample.
