Seventeen new prenylated xanthones (1-17) were isolated from an ethyl acetate-soluble extract of root bark of Cudrania tricuspidata together with 17 previously identified xanthones. The structures of the new compounds were elucidated by spectroscopic methods. Six new compounds (3, 7, 8, 9, 15, and 16) and six known compounds (18-23) showed neuroprotective effects against 6-hydroxydopamine-induced cell death in human neuroblastoma SH-SY5Y cells, with EC50 values of 0.7-16.6 μM.
