► Five furanoditerpenes were isolated and identified from Arcangelisia flava (L.) Merr. ► 2α,3α-Epoxy-2,3,7,8α-tetrahydropenianthic acid methyl ester was isolated and identified. ► The configuration was determined by X-ray analysis and two-dimensional NMR. ► We investigated antifungal activity of the isolated furanoditerpenes.
