Abstract

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.
Muz (Musa sp.) bitkisi tropikal ve subtropikal bölgelerde yetişir. Muzun meyvesi yenir ve kabuğu atılır. Bu çalışmada Brezilya' da yetişen muz kabuğu (Bbp) ve Türkiye' de yetişen muz kabuğundan (Tbp) hazırlanan etil asetat (Ea) ve metanol/kloroform (Me/Ch) ekstraktlarının kimyasal analizleri (HPLC-TOF/MS ve GC-MS) ve biyokimyasal aktiviteleri (antioksidan ve antimikrobiyal) araştırıldı. Seten, 4- hidroksibenzoik, palmitik, linoleik, stearik, gentisik ve siringik asit ekstraktlarda en bol bulunan bileşiklerdir. Tbp-Ea'nın toplam antioksidan aktivitesi (A0.5:36.84 μg/mL), Bbp-Ea'nın lipid peroksidasyonunun inhibisyonu (IC50: 3.22 μg/mL), TbpMe/Ch'nin gücünü azaltma (A0.5:4.96 μg/mL), Bbp-Ea'nın DPPH• temizleme aktivitesi (IC50: 8.54 μg/mL), Tbp-Ea'nın metal şelatlama aktivitesi (IC50: 16.54 μg/mL) ve TbpMe/Ch'nin H2O2 temizleme aktivitesi (IC50: 0.36 μg/mL) en etkili bulundu. Ekstraktların gram negatif ve gram pozitif bakterilere karşı etkiliğini gösterdi. Sonuç olarak, TbP ve Bbp ekstraktlarının fitokimyasal ve biyokimyasal sonuçları daha ileri farmakolojik, biyokimyasal ve farmakolojik araştırmalara katkı sağlayacaktır.
