Abstract
Three novel triterpenoid saponins, dianosides G, H and I, together with the known
saponin, azukisaponin IV, have been isolated from Dianthus superbus var. longicalycinus. The structures of the new saponins have been assigned as indicated in formulas 1,2 and 3, respectively, by spectral and chemical evidence.
