Three new triterpenoid saponins (1-3) were isolated from the dried aerial parts of Dianthus superbus L. (Caryophyllaceae). Their structures were established as 3-O-â-D-glucopyranosyl gypsogenic acid 28-O-[â-D-6-O-((3S)-3-hydroxyl-3-methylglutaryl)glucopyranosyl(1?6)]-â-D-glucopyranoside (1), 3-O-â-D-glucopyranosyl gypsogenic acid 28-O-[â-D-glucopyranosyl(1?3)][â-D-6-O-((3S)-hydroxyl-3-methylglutaryl)glucopyranosyl(1?6)]-â-D-glucopyranoside (2), 3-O-á-L-arabinopyranosyl-3â,16á-dihydroxyolean-12-en-23,28-dioic acid 28-O-[â-D-glucopyranosyl-(1?6)]-â-D-glucopyranoside (3), on the basis of various spectroscopic analyses and chemical degradations.
