  A new anthraquinone glycoside was isolated from the hydrophilic fraction of the Chinese medicinal plant Rhynchotechum vestitum. Its structure was determined as damnacanthol-11-O-beta-glucoside by spectroscopic evidence. The occurrence of rubiadin-1-methylether-3-O-beta-primeveroside, lucidine-3-O-beta-primeveroside and rubiadin-3-O-beta-primeveroside in the plant is reported for the first time.
