[Physcion-8-O-beta-D-gentiobioside, a new anthraquinone glycoside from rhubarb roots].
A new anthraquinone glycoside - physcion-8-O-beta-D-gentiobioside - has been isolated from rhubarb roots in high yield. The structure was confirmed by H-NMR and MS-data as well as by direct comparison with the synthesized compound. The new substance was the main anthraquinone glycoside in some of the investigated samples of rhubarb roots and extracts.
