Özet

The banana (Musa sp.) plant grows in tropical and subtropicalregions. The fruit of the banana is eaten and the peel of thebanana is discarded. In this study, chemical analyzes (HPLCTOF/MS ve GC-MS) and biochemical activities (antioxidantand antimicrobial) of ethyl acetate (Ea) andmethanol/chloroform (Me/Ch) extracts prepared from bananapeel (Bbp) grown in Brazil and banana peel (Tbp) grown inTurkey were investigated. Cetene, 4-hydroxybenzoic, palmitic,linoleic, stearic, gentisic and syringic acid are the mostabundant compounds in the extracts. The total antioxidantactivity of Tbp-Ea (A0.5: 36.84 μg/mL), inhibition of lipidperoxidation of Bbp-Ea (IC50: 3.22 μg/mL), reducing power ofTbp-Me/Ch (A0.5: 4.96 μg/mL), DPPH• scavenging activity ofBbp-Ea (IC50: 8.54 μg/mL), metal chelating activity of Tbp-Ea(IC50: 16.54 μg/mL) and H2O2 scavenging activity of TbpMe/Ch (IC50: 0.36 μg/mL) were found the most effective. Itwas exhibited that extracts were effective against gramnegative and gram-positive bacteria. In conclusion, thephytochemical and biochemical results of the TbP and Bbpextracts will contribute further pharmacological, biochemicaland pharmacological investigations.
