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 monosaccharides at C-3 and four or five monosaccharides at C-28. Their structures were established on the basis of spectroscopic and chemical evidence.
