摘要
Objective:In this study,five woody plants including Cotoneaster horizontalis(rockspray cotoneaster),Cotoneaster franchetii(orange cotoneaster),Elaeagnus angustifolia(Oleaster),Berberis thunbergii(Japanese barberry),and Malus floribunda(Japanese crabapple)were used for infusion preparation.Materials and Methods:The antioxidant potential and bioaccessibility of phenolics in the infusion were investigated before and after the simulation of in vitro gastrointestinal digestion.Results:Accordingly,the infusion of B.thunbergii(Japanese barberry)exhibited the highest antioxidant capacity(6418±479 mg Trolox equivalents[TE]/100 g dry weight[dw]),as measured by CUPRAC assay,and the highest total phenolic content(689±30 mg gallic acid equivalents/100 g dw).On the other side,the infusion of C.horizontalis(rockspray cotoneaster)had the greatest antioxidant capacity values determined by 1,1-diphenyl-2-picrylhydrazyl radical scavenging ability(2420±132 mg TE/100 g dw).The stability of phenolics in infusions was found to vary from gastric to intestinal digestion passage.Conclusion:With their high antioxidant potential,it is clear from the results that these plants can be considered a good alternative with functional properties.
