Flavonol 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...
