In-vitro analysis of potential antibacterial activity of three medicinal plants
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 3
Abstract
he present study was aimed to examine and compare the antibacterial activity of hot methanolic extract of medicinal plants viz. Portulaca oleracea (purslane), Syzygium cumini (L.) (jamun), Psidium guajava (L.) (guava). Antibacterial activity was carried by using agar well diffusion method, against Gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) and Gram-negative bacteria (Escherichia coli). Results indicated that all the three plant extracts possess antibacterial property against Gram-positive bacteria and no activity was found against Gram-negative bacteria. Moderate zone of inhibition against Staphylococcus aureus and Bacillus subtilis was exhibited by S. cumini (L.) (11mm and 12mm) and P. guajava (L.) (10mm and 11mm) and weak zone of inhibition was exhibited by P. oleracea (5 mm and 6mm). In conclusion, S. cumini (L.) and P. guajava (L.) possess better capabilities of being a good candidate in search for natural antibacterial agent against infections and diseases causing Gram-positive bacteria as compared to P. oleracea.
