Investigation of an ethanol extract from the stem bark of Morus wittiorum led to the isolation of five new 2-arylbenzofuran derivatives that were named wittifuran S, wittifuran T, wittifuran V, wittifuran W and wittifuran X (1-5). Structures were determined on the basis of spectroscopic analysis. Two new wittifurans and five previously isolated compounds were assayed for antioxidant and anti-inflammatory activity.
