Two new neolignans, madangones A (1) and B (2), together with (+)-kunstlerone (3), vanillin, vanillic acid, betulin, β-sitosterol and β-sitostenone, were isolated from the stem bark of Beilschmiedia madang (Lauraceae). The structures of the compounds were determined by spectroscopic means. The compo...
