Plants like pineapple and coconut are able to exhibit inhibitory effect against the growth of most food borne pathogens,due to the presence of various secondary metabolites. The aim of this study is to investigate the phytochemical constituents and antimicrobial activities of aqueous and ethanolic extracts of pineapple (Ananas comosus) peel and coconut (Cocos nucifera) kernel on some selected food borne pathogens. Antimicrobial analysis of aqueous and ethanolic extracts prepared from coconut kernel and pineapple peel were done by using the agar well diffusion method against the selected food borne pathogens. The ethanolic kernel extracts of coconut showed a remarkable inhibition zone against Bacillus cereus (18.0±0.13mm) followed by Klebsiella pneumonia (15.0±0.18mm) and Staphylococcus aureus (12.0±0.4mm). Whereas, the aqueous kernel extracts of coconut showed maximum inhibition zone against B. cereus (16.0±0.6mm) followed by S. aureus (15.7±0.9mm) and Escherichia coli (15.0±0.10mm). In addition the ethanolic peel extract of pineapple showed maximum inhibition zone against B. cereus (15.0±0.6mm) followed by S. aureus (14.0±0.22mm) and E. coli (12.3.0±0.12mm), whereas its aqueous peel extract resulted in maximum inhibition zone against B. cereus, (14.0±0.5mm), S. aureus (14.0±0.11mm) and K. pneumonia (14.0±0.10mm). Streptomycin, the reference antibiotic, had inhibitory zones on the tested organisms ranged between 10.0 and 24.0 mm. The minimum inhibition zone of the tested extracts against the tested organisms ranged from 5.0 mm to 14.0mm. The phytochemical analysis showed presence of oxalate, alkaloids, phytate, tannins and glycoside. The antimicrobial activities of the extracts of both C. nucifera kernel and A. comosus peel have capable of inhibitory effect against the target organisms.
