An anthraquinone glucodise, lucidin w-o-B-D-glucodise, and three anthraquinones i.e. lucidin w-ethyl ether, hystazarin monomethyl ether and 1,6/1,7-dihydroxy-2-acetyloxy anthraquinone have been isolated from the root of Morinda talmyi Pierre. Lucidin w-o-B-D-glucoside and 1,6/1,7-dihydroxy-2-acetyloxy anthraquinone have never been reported to be found in this genus before. Their chemical and physical properties were studied.
