experimental part, p. 518 - 521 (2011/06/21)
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-β-D-glucopyranosyl gypsogenic acid 28-O-[β-D-6-O- ((3S)-3-hydroxyl-3-methylglutaryl)glucopyranosyl(1→6)]-β-D- glucopyranoside (1), 3-O-β-D-glucopyranosyl gypsogenic acid 28-O-[β-D-glucopyranosyl(1→3)][β-D-6-O-((3S)-hydroxyl-3- methylglutaryl)glucopyranosyl(1→6)]-β-D-glucopyranoside (2), 3-O-α-L-arabinopyranosyl-3β,16α-dihydroxyolean-12-en-23, 28-dioic acid 28-O-[β-D-glucopyranosyl-(1→6)]-β-D-glucopyranoside (3), on the basis of various spectroscopic analyses and chemical degradations.

experimental part, p. 68 - 73 (2011/03/19)
Six new triterpenoid saponins (1-6) have been isolated from the roots of Gypsophila pacifica Kom. Their structures were established on the basis of extensive NMR (1H, 13C, TOCSY, HSQC, and HMBC) and ESIMS studies.

, p. 56 - 60 (2007/10/02)
From the epigeal part of the plant Climacoptera transoxana (Iljin) Botsch. have been isolated new triterpene glycosides - copterosides G and H, which are bisdesmosidic glycosides.On the basis of chemical transformations and spectral characteristics, copteroside G has been assigned the structure of gypsogenic acid 28-O-β-D-glucopyranoside 3-O-β-D-glucuronopyranoside, while copteroside H is gypsogenic acid 28-O-β-D-glucopyranoside 3-O-2)-β-glucuronopyranoside>.
