Citrus plant is the source of vitamine C, high nutrient value and enormous antioxidant activity. Citrus plant such as Punica granatum Linn, Punica granatum, Citrus pseudolimon, and Citrus sinensis were used for present study. Ethanol and hexane solvant system were used to prepare peel extract. Antimicrobial activity of peel extract and MICs of juice were performed against three pathogenic strains of C. ablicans, S. aureus and E. coli. Ethanolic peel extract show highest antimicrobial activity (zone of inhibition) compare to hexane peel extract. Among the plant species Punica granatum Linn express highest zone of inhibition against the microorganism with 9 mm of inhibition zone. 75% concentration of Citrus sinensis juices showed minimum inhibitory concentration (MIC) against S. aureus compare to E coli. All the citrus plants exhibited positive control against microbes so the peel extract and fruit juice utilized as potential microbial resistant resource.

Punica granatum Linn, Citrus pseudolimon, Citrus sinensis, antimicrobial activity.
