A new biflavonoid, ent-ruixianglangdusu B (1), together with three known compounds, namely ochnaflavone (2), (-)-epicatechin (3) and kaempferol-3-O-α-L-rhamnopyranoside (4) were isolated from the leaves of Ochna lanceolata. The structures of these compounds were determined by means of spectral and chemical studies.
