Physcion-8-O-β-D-gentiobiosid, ein neues Hauptglykosid aus Radix Rhei

Abstract

A new anthraquinone glycoside - physcion-8-O-β-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. 1 Teil der Diplomarbeit L. HOLZSCHUH, Univ.
