Anti-microbial activity of garcinia gummigutta fruit rind

Abstract

The objective of the present study was to evaluate the in-vitro anti microbial activity of fresh and dry rinds of Garcinia gummigutta fruit in methanolic extract against food borne illnesses causing pathogens. The fruit rinds extracts were examined to evaluate the antimicrobial activity against 3 Gram-positive Bacteria i.e. Bacillus subtilis and Staphylococcus aureus and Enterococcus fecalis, 2 Gram-negative bacteria Escherichia coli and Shigella boydii, using Agar well diffusion antimicrobial assay. The zone of inhibition was nil at the concentration of 1g/100ml. However the minimum zone of inhibition was found at the concentration rate of 10g/100ml in Enterococcus fecalis (13.59mm), Shigella (12.89mm), Bacillus subtilis (12.69mm), Escherichia coli (11.68mm) and Staphylococcus aureus (9.75mm) respectively. Since the extracts showed a broad spectrum of antimicrobial activity on both gram positive and negative bacterial isolates, Garcinia gummigutta can be used as a bio preservative or neutraceuticals or therapeutic agent to prevent several diseases.
