Phytochemical analysis and antibacterial efficacy of fruit rind of Baccaurea courtallensis Muell. Arg.

The experiment was carried out to extract the phytochemical constituents of the Baccaurea courtallensis Muell. -Arg. from fruit rind and to find out the antibacterial efficacy of the extract. The methanol and benzene extracts of Baccaurea courtallensis were subjected to preliminary phytochemical analysis and they showed the presence of steroids, coumarins, tannins, flavanoids, phenols, quinones and volatile oils. The methanol and benzene extracts were tested for antimicrobial efficacy against human pathogenic bacteria (Escherichia coli, Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa, Klebsiella pneumoniae). The minimum inhibitory concentration (MIC) value of the two extracts against susceptible pathogenic bacteria was estimated. The methanol extract showed a highest antibacterial activity at 60µg/ml concentration followed by benzene extract at 70µg/ml. The minimum inhibitory concentration (MIC) value for E. coli was 70µg/ml and for S. aureus was 80µg/ml. The most susceptible bacteria in the analysis was E. coli, followed by S. aureus.
