Abstract
Whole roots of Morinda citrifolia yielded nordamnacanthal (1.7%), morindone (0.5%), rubiadin, and rubiadin-1-methyl ether as the principal pigments. Damnacanthol was isolated as a new derivative, which is probably an artifact, and another minor component is believed to be soranjidiol (1,6-dihydroxy-2-methylanthraquinone). Rubiadin and rubiadin-1-methyl ether have also been isolated from a small sample of the root bark of M. jasminoides.Keywords
