Flavonoid glycosides from Cotoneaster thymaefolia

Phytochemistry, 1994
Abstract A new C-glycoside, vitexin-2″-O-α- d -arabinofuranoside, was isolated from the leaves of Cotoneaster thymaefolia. Vitexin, vitexin-2″-O-rhamnoside, rutin, quercetin 3-rhamnoside, 5,7,2′,5′-tetrahydroxyflavanone and its 7-glucoside were also identified. The structures of the compounds were determined by spectroscopic methods.

Flavonoid glycosides from Eugenia jambos

Phytochemistry, 1994
Two flavonol diglycosides isolated from the leaves of Eugenia jambos were characterized as quercetin and myricetin 3-O-beta-D-xylopyranosyl(1-->2) alpha-L-rhamnopyranosides by means of spectral analyses applying 2D NMR techniques and NOE experiments.

Flavonoid glycosides from Barringtonia acutangula

Bioorganic & Medicinal Chemistry Letters, 2017
Using various chromatographic separation techniques, ten flavonoid glycosides, including six new compounds namely barringosides A-F (1-6), were isolated from a methanol extract of the Barringtonia acutangula leaves. The structure elucidation was confirmed by spectroscopic analyses, including 1D and 2D NMR, and HR ESI MS. Their inhibitory effects on LPS-

Flavonoid glycosides from Cassia alata

Phytochemistry, 1991
Two new glycosides, chrysoeriol-7-O-(2"-O-beta-D-mannopyranosyl)-beta-D-allopyranos ide and rhamnetin-3-O-(2"-O-beta-D-mannopyranosyl)-beta-D-allopyranosid e, were isolated from the seeds of Cassia alata. The structures were established on the basis of chemical evidence and spectroscopic methods, especially NMR.

Investigation of flavonoid glycosides

Chemistry of Natural Compounds, 1965
1. The method of differential analysis in the IR region of the spectrum has been used in an investigation of the structure of the carbohydrate part of flavonoid glycosides. This method permits the pyranose and furanose forms of the carbohydrate substituents, the α- and β-anomers of the pyranosides and other structural features characterizing the nature
