Reactive Radical Scavenging And Xanthine Oxidase Inhibition Of Proanthocyanidins From Carallia Brachiata

Keywords

Abstract

Antioxidant-guided separation of Carralia brachiata bark led to a new A-type trimeric proanthocyanidin named carallidin (1), along with mahuannin A (2) and p-hydroxy benzoic acid (3). The structure of 1 was fully characterized by interpretation of spectroscopic data and chemical means. Compounds 1 and 2 exhibited radical scavenging against DPPH (IC50 102 and 182 μM) and superoxide radical (IC50 1.47 and 9.74 μM). In addition, 1 and 2 also inhibited xanthine oxidase with IC50 values of 12.9 and 16.0 μM. Copyright © 2006 John Wiley & Sons, Ltd.
