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.

Phase-Transfer-Catalyzed Synthesis of Flavonoid Glycosides

Planta Medica, 1990
Phase-transfer-catalyzed glycosylation of flavonoid aglycons appears to be a facile method for flavonoid glycosides synthesis, the stereospecificity of the reaction appears to be good, except for the L-rhamnose ...

The flavonoid glycosides of Salix purpurea

Phytochemistry, 1967
Abstract Isosalipurposide, the 2′-glucoside of chalconaringenin, has been shown to be the principal flavonoid of young bark of Salix purpurea ; in the old bark it is accompanied by isomeric forms of naringenin 5-glucoside, salipurposide. The leaf of S.
