A new anthraquinone glycoside was isolated from the hydrophilic fracti
on of the Chinese medicinal plant Rhynchotechum vestitum. Its structur
e was determined as damnacanthol-11-O-beta-glucoside by spectroscopic
evidence. The occurrence of rubiadin-1-methylether-3-O-beta-primeveros
ide, lucidine-3-O-beta-primeveroside and rubiadin-3-O-beta-primeverosi
de in the plant is reported for the first time. (C) 1998 Elsevier Scie
