N2  - The root bark of Ventilago viminalis Hook. contains three new colouring matters now named ventimalin, viminalin, and ventilagone. The first of these has been identified as 1,3,4,5,6-pentahydroxy-2-methylanthraquinone and the structure has been confirmed by synthesis. Viminalin is shown to be the 4,5-dimethyl ether of ventimalin. Ventilagone is apparently a naphthoquinone of the hydroxy- juglone type. Two known anthraquinones, chrysophanol and islandicin, have also been isolated and there is evidence for the presence of helminthosporin.
