Anti-Oxidative and Nitric Oxide Production Inhibitory Activities of Phenolic Compounds from the Fruits of Actinidia arguta

Phytochemical examination of the fruits of Actinidia arguta has led to the isolation three organic acids, one coumarin, and three flavonoids. Structures of these compounds were elucidated as protocatechuic acid (1), caffeic acid (2), caffeoyl-β-D-glucopyranoside (3), esculetin (4), quercetin (5), quercetin 3-O-β-Dgalactopyranoside (6), and quercetin 3-O-α-L-rhamnopyranosyl (1 → 6)-O-β-D-glucopyranoside (7) by comparisons with previously reported...
