Abstract:

A preliminary antibacterial evaluation of passion fruit juice was performed in this paper. Passion fruit juice had strong inhibitory effect on Escherichia coli, Staphylococcus aureus, Candida tropicalis and Aspergillus niger. The ethanol-acetone (1:1, V/V) extract from the juice also had inhibitory effect on E. coli, S. aureus, C. tropicalis and A. niger with minimum inhibitory concentrations (MICs) of 125, 250, 500 mg/mL and 500 mg/mL, respectively. The cyclohexane extract from the juice had inhibitory effect on E. coli, S. aureus with a MIC of 250 mg/mL but no inhibitory effect on C. tropicalis and A. niger.

Key words: passion fruit juice, antibacterial activity, ethanol-acetone extract, cyclohexane
