Previousinvestigation of the species resulted in the isolation and identification of triterpenes,triterpenoid saponins, cyclic pentapeptides, and oligopeptides. We have also reported thepolyphenols and a dipeptide isolated from the species. In this paper, the isolation and structureelucidation of three anthraquinones, chrysophanol (1), physciori (2), and emodin (3), are described.Chrysophanol and physcion were isolated from family Composi-tae for the first time.展开更多

(Compositae). and its structure was elucidated on the basis of spectral and chemical methods. Aster saponin G is 3-0[α-L-arabinopyranosyl-(1→6)-β-D-glucopyranosyl]-2β,3β, 16α-trihydroxyolean-12-en-28-oic acid(asterogenic acid) 28-0-[β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-xylopyranosyl] ester展开更多
Two new oligopeptides, Asterin A and B, have been isolated from the roots of Aster tataricus L. f., and their structures were elucidated on the basis of spectroscop- ic, chemical and enzymatic methods.
