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

Flavonoid glycosides from Salvia moorcroftiana Wall.

Carbohydrate Research, 2002
Phytochemical analysis of the whole plant of Salvia moorcroftiana Wall. (Lamiaceae) resulted in the isolation of two new flavonoid glycosides, together with three known compounds. The structures of the new compounds were established as genkwanin 4'-O-alpha-L-arabinopyranosyl-(1-->6)-beta-D-galactopyranoside (1) and genkwanin 4'-O-[alpha-L ...

Antioxidant flavonoid glycosides from Evolvulus alsinoides

Fitoterapia, 2010
Oxidative damage is an established outcome of chronic stress. Thus, the present study was designed to investigate the modulatory role of ethanolic extract of Evolvulus alsinoides (EA) in terms of oxidative alterations at peripheral and central level in rats subjected to chronic unpredictable stress (CUS).

Acylated flavonoid glycosides from Bassia muricata

Phytochemistry, 2001
From the arial parts of Bassia muricata, two acylated flavonoid glycosides quercetin-3-O-(6"-caffeoyl)-sophoroside and quercetin-3-O-(6"-feruloyl)-sophoroside have been isolated together with two known flavonoid glycosides quercetin-3-O-sophoroside and quercetin-3,7-O-beta-diglucopyranoside, as well as four known triterpenoidal saponins, oleanolic acid-
