Four new triterpenoid saponins were isolated from the roots of Gypsophila paniculata and G. arrostii. Their structures were elucidated using a combination of homo- and heteronuclear 2D NMR techniques, without having recourse to chemical degradation or modification. The saponins investigated are: 3-O-beta-D-galactopyranosyl-(1----2)-[beta-D-xylopyranosyl-(1----3)]-bet a-D- glucuronopyranosyl quillaic acid 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)]-alph a- L-rhamnopyranosyl-(1----2)-beta-D-fucopyranoside; 3-O-beta-D-galactopyranosyl-(1----2)-[beta-D-xylopyranosyl-(1----3)]-bet a- D-glucuronopyranosyl quillaic acid 28-O-beta-D-arabinopyranosyl-(1----4)-beta-D-arabinopyranosyl++ +-(1----3)-beta-D- xylopyranosyl-(1----4)-alpha-L-rhamnopyranosyl-(1----2)-beta-D-fucopyran oside; 3-O-beta-D-glucopyranosyl-(1----2)-beta-D-glucuronopyranosyl gypsogenin 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)]-alph a- L-rhamnopyranosyl-(1----2)-beta-D-fucopyranoside; 3-O-beta-D-xylopyranosyl-(1----3)-[beta-D-galactopyranosyl-(1----2)]-bet a- D-glucuronopyranosyl gypsogenin 28-O-beta-D-glucopyranosyl-(1----3)-[beta-D-xylopyranosyl-(1----4)-alpha -L- rhamnopyranosyl-(1----2)-beta-D-fucopyranoside.

D009828	Oleanolic Acid	A pentacyclic triterpene that occurs widely in many PLANTS as the free acid or the aglycone for many SAPONINS. It is biosynthesized from lupane. It can rearrange to the isomer, ursolic acid, or be oxidized to taraxasterol and amyrin.	Oleanol,Hederins,Oleanane Triterpenes,Triterpenes, Oleanane
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant

D012503	Saponins	A type of glycoside widely distributed in plants. Each consists of a sapogenin as the aglycone moiety, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar may be glucose, galactose, a pentose, or a methylpentose.	Saponin
