Bioactive ellagitannins from Cunonia macrophylla, an endemic Cunoniaceae from New Caledonia

Ellagitannins identified as ellagic acid-4-O-β-d-xylopyranoside, mallorepanin, mallotinic acid along with corilagin, chebulagic acid, ellagic acid and gallic acid were isolated from Cunonia macrophylla leaves. Their antimicrobial activities on human and plant pathogens and their inhibitory effects against xanthine oxidase were investigated and revealed bioactivities first time detected.
