Screening of antimicrobial properties from local edible and flowering plants at Mengabang Telipot, Terengganu, Malaysia

Abstract

Antimicrobial activity of methanol crude extract of edible and flowering plants were investigated to determine the antimicrobial activity. The objective of these studies to find new sources of antimicrobial. Antimicrobial activity of methanol plant extracts were evaluated against gram negative bacteria (Vibrio spp, Flavobacterium spp, Aeromonas spp, Aeromonas hydophilla, Vibrio fluvalis, Esoherichia coli) and gram positive bacteria.( Streptococcus aglactica). The MIC value of plant extracts were determined by two -fold serial dilution . Nine plants extracts exhibited antimicrobial activity against one or more of tested bacteria at different concentrations. Among the tested plants, the highest antimicrobial activity was exhibited by methanol extract of Stanolobium stans L. But most of plants were consider having weak antimicrobial activity. This study showed the these plants have the potential as an alternative to antibiotic.
