Abstract:

Orange and lemon peels (OP&LP) are common citrus byproducts, contain biologically active compounds. This work aimed to identify the potential of OP and LP extracts in terms of their antibacterial, antioxidant activities and total phenolic content. Antibacterial activity was determined and compared to control and Ampicilline. Ethanolic extract of microwave dried LP displayed high inhibition of some bacteria compared to methanolic extract. The air-oven dried LP extracted by methanol showed low antibacterial activity. Microwave dried OP extracted with ethanol inhibited: L. monocytogenes, B. subtilis, P. aeruginosa and E. coli, while methanolic extract inhibited B. subtilis, E. coli and P. aeruginosa. Inhibition zone size was less in the used extracts of dried air-oven peels. The antioxidant activity of the tested peel extracts was determined by DPPH, FRAP and OH scavenging activity methods. Total phenolics of both OP&LP extracted with ethanol were higher than in methanol extract.
