Antibacterial Activities of Selected Fruit Peels against Organisms Associated with Urinary Tract Infection

Abstract

The use of natural products as anti-infective agents, have given rise to new chemical diversity and are preferred in modern world. Among all these natural sources, plants and its products is more reliable because of its renewability.Urinary tract infections (UTIs) are among the most common infectious diseases occurring in either the community or healthcare setting. Orange and Plantain peels were used to determine the antibacterialactivities. A measure of 50 grams of powder was filled in the thimble and extracted with 150 ml of ethanol successively up to 48 hours. The solvent extracts were concentrated separately under reduced pressure, 2g of each concentrated solvent extracts weredissolved in 20 ml of 20% dimethyl sulphoxide and used for antibacterial assays using agar well diffusion and broth method. The phytochemical analysis of sweet orange peel shows that carbohydrate, reducing sugars, tannins and flavonoids were present, The zone of inhibition effect of the extracts on selected organism was concentration dependent (25<50<75<100). Higher concentration of extract recordedlarger/wider effect on each test organism.Musa paradisiacalpeel showed no effect on test organism except at 100mg/ml that recorded 4.7±0.47mm against E. coligrowth. The MIC and MBC of both orange peel and plantain peels suggest potency against test organisms.Orange peel has advantage over plantain peel;S. aureus, E. coli and P. aeruginosawere susceptible tothe extract exemptingK. pneumonia, whichshowed no susceptibility to the duo extracts. The peels of Citrus sinensisand Musa paradisiacalexhibited inhibitory activity against certain bacteria, which can be attributed to the presence of certain secondary metabolites. But when compared with standard antibiotics, the ethanoic extracts of the duo was less efficient as there was a smaller size of zone of inhibition against the luxurious growth of tested organism
