T. Miyase et al., STUDIES ON THE CONSTITUENTS OF SOLIDAGO-VIRGA-AUREA L .3. STRUCTURES OF SOLIDAGOSAPONINS XXI-XXIX, Chemical and Pharmaceutical Bulletin, 42(3), 1994, pp. 617-624
From the most polar fractions of Solidago virga-aurea L. (Compositae),
9 oleanane-type triterpene saponins named solidagosaponins XXI-XXIX (
1-9) were isolated, together with a known saponin, virgaureasaponin 2
(10). These saponins are bisdesmosidic glycosides having two monosacch
arides at C-3 and four or five monosaccharides at C-28. Their structur
es were established on the basis of spectroscopic and chemical evidenc
e.
