Evaluation of anti bacterial activity of fruit rind extract of Garcinia mangostana Linn on enteric pathogens-an in vitro study

The aim of the present study was to evaluate the anti bacterial activity of fruit rind extract of Garcinia mangostana Linn on selected enteric pathogens. Garcinia mangostana, known simply as mangosteen has a diverse pharmacological and phytochemical importance and is a potent medicinal plant in the traditional Indian medicinal systems. Antibacterial activity of ethanolic and aqueous fruit rind extract of Garcinia mangostana was screened against Salmonella typhi, [Gram negative bacilli-GNB], Shigella dysentriae[GNB], E.coli[GNB], Klebsiella pneumoniae[GNB], Vibrio cholerae[GNB], Pseudomonas aeruginosa[GNB] and Staphylococcus aureus,[Gram positive cocci] using agar well diffusion technique. The results of this study showed that both the extracts at different concentrations exhibited anti bacterial activity against the bacterial species tested. The ethanolic extract showed higher degree of activity than aqueous extract compared with the standards.
