Abstract
1:3:8-Trihydroxy-2-hydroxymethylanthraquinone has been synthesised by hydroxymethylation of 1:3:8-trihydroxyanthraquinone and shown to be different from versicolorin, the colouring matter isolated by Hatsuda and Kuyama from Aspergillus versicolor. Damnacanthol and damnacanthal, the colouring matters of the roots of Damnacanthus major and D. indicus have been synthesised by a new route.
