Resumen:
Vitis tiliifolia is a tropical grape with a deep purple colour and a high content of pigments. Total polyphenols content in the skin and pulp was 400.35 and 171.26 mg GAE/g dry sample of Vitis tiliifolia, respectively, which coincides with DPPH radical scavenging for skin (91.39%) and in the pulp (19.57%). The predominant individual phenolic compounds found in the skin were quercetin-3-glucoside (39.86 µg/g), rutin (37.01 µg/g) and transresveratrol (32.88 µg/g). The DPPH radical scavenging and reducing power revealed a high antioxidant activity. This study demonstrates that wild grape can thus be utilised as a novel functional resource. © 2018 Chiriotti Editori. All rights reserved.
