N2  - Extraction of the leaves of Harungana madagascariensis Poir. (Guttiferae) gave &#946;-sitosterol, quercetin, diisopropyl 4,4'-methylenedicarbanilate (probably an artefact), and a new pigment, madagascarin. Mainly by spectroscopic methods the structure of the latter was established as 2,7'-biemodyl (1,3,8,l?,6',8'-hexahydroxy- 6,3'-dimethyl-2,Z'-bianthraquinone).
