The antioxidant property and α-amylase inhibition activity of young apple polyphenols are related with apple varieties

In this study, compositional profile, antioxidant activities and α-amylase inhibition of young apple polyphenols (YAP) from five cultivars (Short-branch Fuji, Pink Lady, Jinshiji, Ruiyang and Qinyang) were investigated. The possible inhibition mechanism of YAP on porcine pancreatic α-amylase (PPA) was studied through kinetic analysis, fluorescence quenching (FQ) and differential scanning calorimetry (DSC). The results showed that YAP exhibited...
