Abstract

The total phenolic contents and in vitro comparative anti bacterial activities of aqueous of unripe pawpaw peel against gram positive and gram negative bacteria were investigated using standard methods of analysis. Unripe papaya peels has a long history and proof of being an effective medicinal fruit used to treat some human ailments. The study examined the aqueous extracts of both oven air dried and sun dried unripe papaya peels for the possible anti oxidants and anti microbial properties. The result revealed that extract of oven air dried unripe pawpaw peel was richer in total phenol (23.949mgGAE/g) than extracts of sun dried unripe papaya peel with total phenolic contents of 21.095 mgGAE/g. Also, the oven air dried papaya peel extract shows maximum zone of inhibition of 12mm against Escherichia coli in the anti bacterial assay. However, sun dried unripe peel extract showed no zone of inhibition against Bacillus spp. Therefore, unripe papaya peels can be therapeutically used in the management and treatment of some infectious diseases as well as oxidative stress induce human ailment because of their anti microbial potency due to their high total phenolic contents.
