Antioxidant-guided separation of Carallia brachiata bark led to a new A-type trimeric proanthocyanidin named carallidin (1), along with mahuarmin 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 mu m) and superoxide radical (IC50 1.47 and 9.74 mu m). In addition, 1 and 2 also inhibited xanthine oxidase with IC, values of 12.9 and 16.0 mu m. Copyright (c) 2006 John Wiley & Sons, Ltd.
