Abstract

After further investigation of more polar fractions of Solidago virga-aurea L. (Compositae), 11 new oleanane-type saponins named solidagosaponins X-XX (1-11) were isolated, together with two known saponins, virgaureasaponin 1 (12) and bellissaponon BA₂ (13). These new saponins contain various acyl groups, and four of them were tridesmosidic glycoside. Their structures were established on the basis of spectroscopic and chemical evidence.
