This study has been designed to screen phenolic compounds of strawberry pomace obtained from two strawberry cultivars, 'Clery' (SC) and 'Marmolada' (SM), and their biological activity (O2•-, •OH, DPPH• and ABTS+• antioxidant capacity, α-glucosidase inhibition and reducing power). The SM pomace contained significantly higher (p < 0.05) amounts of total flavonoids and anthocyanins, individual phenolic acids and flavonoids, among them protocatechuic acid, catechin and pelargonidin-3-glucoside (1838.31 and 1646.68 per 100 g DW, respectively) being the most abundant. The SM pomace showed higher DPPH• and ABTS+• antioxidant capacities and reducing power, as well as higher activity towards O2•- (EC50O2•- = 0:12 mg mL-1), •OH (EC50•OH = 2.77 mg mL-1) and α-glucosidase inhibitory potential (EC50α-GIP = 1.16 mg mL-1). Our results support the use of strawberry pomace as a rich source of phytochemicals for further utilization in the food industry as supplements or ingredients for food fortification. | URI: | https://open.uns.ac.rs/handle/123456789/6561 | ISSN: | 20462069 | DOI: | 10.1039/c4ra14296a |
