Title: Antioxidant Activities of Different Solvents Extracts from Apple Peels
Abstract: To explore the antioxidant activities of different solvent extracts from apple peels.The extracts of the antioxidants from apple peels were extracted with distilled water,60% ethanol,anhydrous ethanol and ethyl acetate,respectively.Using Vc as a positive control,antioxidant activities of the extracts were tested and compared by hydroxyl radicals(.OH) scavenging activity,superoxide radical(O2-.) scavenging activity,nitrite radical(NO2-) scavenging activity and reducing power,and the total phenols contents of the extracts were also determined by the Folin-Ciocalteu method.The contents of total phenols from the 60% ethanol extract were significantly higher than those in the other three extracts.All the four extracts exhibited antioxidant capacities in a significant dosage-dependent manner.The 60% ethanol extract had the strongest antioxidant activities,the scavenging capacity to.OH and O2-.of 60% ethanol extracts were weaker than Vc,but the scavenging capacity to O2-and the reducing power were stronger than Vc.The antioxidant substances from apple peels were main in the 60% ethanol extract.
