Flavonol glycosides from the south African medicinal plant Sutherlandia frutescens.
Phytochemical investigation of the leaves of Sutherlandia frutescens led to the isolation of four new 3-hydroxy-3-methylglutaroyl-containing flavonol glycosides, sutherlandins A-D ( 1- 4). Their structures were elucidated by chemical and spectroscopic methods as quercetin 3- O- beta- D-xylopyranosyl(1 --> 2)-[6- O-(3-hydroxy-3-methylglutaroyl)]- beta- D-glucopyranoside ( 1), quercetin 3- O- bet...
متن کاملFlavonol glycosides from Epimedium pubescens.
Five new flavonol glycosides (1, 3, 5-7) were isolated from the aerial parts of Epimedium pubescens Maxim., along with two known compounds, sagittasine C (2) and 4',5-dihydroxyl-8-(3,3-dimethylallyl)-flavonol 3-O-[β-D-xylopyranosyl(1→3)-4-O-acetyl-α-L-rhamnopyranoside]-7-O-β-D-glucopyranoside (4). The structures were elucidated on the basis of their 1D-, 2D-NMR, MS, UV and IR spectra data.
متن کاملFlavonol glycosides from Cadaba glandulosa.
A new flavonol triglycoside, rhamnocitrin-3-O-neohesperoside-4'-O-glucoside was isolated from the ethanol extract of Cadaba glandulosa together with two known diglycosides rhamnocitrin-3-O-neohesperoside and rhamnetin-3-neohesperoside. Characterization of the three compounds was achieved by various spectroscopic methods.
متن کاملFlavonol Glycosides from Paederia scandens
Four kaempferol glycosides and five quercetin glycosides have been isolated from a methanolic extract of Paederia scandens var. mairei leaves and stems, in which in addition four un known glycosides of kaempferol and quercetin are present in a trace. Nine flavonol glycosides including a new glycoside quercetin 3-0-rutinoside-7-0-xylosylglucoside (paederinin) were identified by PC, HPLC, UV spe...
متن کاملFlavonol Glycosides from Euphorbia microsciadia Bioss. with their Immunomodulatory Activities
Four known flavonoids: quercetin 3-O-β-D-rutinoside (Q3Rut), myricetin 3-O-β-D-galactopyranoside (M3Gal), quercetin 3-O-β-D-galactopyranoside (Q3Gal) and quercetin 3-O-β-D-glucopyranoside (Q3Glc), for the first time were isolated from aerial parts of Euphorbia microsciadia. The chemical structure of them was elucidated on the basis of 1 and 2 D-NMR spectra and different spectroscopic techniques...
