Oleanane-type triterpene saponins from Hydrocotyle nepalensis.
Five new oleanane-type triterpene saponins including steganogenin 3-O-β-D-glucopyranoside (1), steganogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (2), steganogenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), chichipegenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (4) and chichipegenin 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (5), along with four known olean...
متن کاملAcetylated triterpene saponins from the Thai medicinal plant, Sapindus emarginatus.
From the pericarps of Sapindus emarginatus (Sapindaceae), three new acetylated triterpene saponins were isolated together with hederagenin and five known triterpene saponins, as well as one known sweet acyclic sesquiterpene glycoside, mukurozioside IIb. The structures of new compounds were elucidated as hederagenin 3-O-(2-O-acetyl-beta-D-xylopyranosyl)-(1-->3)-alpha-L-rhamnopyranosyl-(1-->2)-al...
متن کاملDammarane-type triterpene saponins from the flowers of Panax notoginseng.
Four new dammarane-type triterpene saponins named floranotoginsenosides A (1), B (2), C (3) and D (4), together with five known triterpene saponins, were isolated from the flowers of Panax notoginseng. Their structures were elucidated on the basis of spectral and chemical evidence.
متن کاملTriterpene saponins from the roots of Ilex pubescens.
Five new triterpene saponins, Ilexpublesnins N-R (1-5), along with seven known analogs were isolated from the root of Ilex pubescens. Their structures were elucidated on the basis of extensive spectroscopic analysis, including 1D and 2D NMR experiments. Ilexpublesnin N (1) possessed a rare 20-hydroxyursolic acid scaffold from natural resource. These compounds were evaluated in vitro for their c...
متن کاملHepatoprotective triterpene saponins from the roots of Glycyrrhiza inflata.
Two novel oleanane-type triterpene saponins, licorice-saponin P2 (1) and licorice-saponin Q2 (3), together with nine known compounds 2, 4-11, have been isolated from the water extract of the roots of Glycyrrhiza inflata. The structures of these compounds were elucidated on the basis of spectroscopic analysis, including 2D-NMR experiments (1H-1H COSY, HSQC, HMBC and ROESY). In in vitro assays, c...
