Antioxidant Flavonoid Glycosides
In this thesis the chemical composition of heartsease (Viola tricolor L.) was studied to support the evidence-based determination of its biological activities. Henceforth, a proper sample preparationmethodwas developed, yielding a fraction rich on polar constituents (characteristic of the traditionally applied aqueous extract), which was further separated by conventional Sephadex LH-20 column c...
متن کاملCytotoxic Flavonoid Glycosides from Rapistrum rugosum L.
Five flavonoid glycosides were isolated from the n-butanol soluble fraction of the ethanolic extract of Rapistrum rugosum and their structures were assigned from 1H- and 13C-NMR spectra (DEPT) with 2D NMR as quercetin-3-O-α-L-rhamnopyranoside (1), quercetin-3-O-β-D-xyloside (2), quercetin, 3-O-α-L-arabinopyranoside,7-O-α-L-rhamnopyranoside (3), kaempferol 3-O-α-L-arabinopyranoside, 7-O-α-L-rham...
متن کاملFlavonoid Glycosides from Tribulus terrestris L. orientalis
Tribulus terrestris L. var. orientalis (Kerner) G. Beck is widely used in the traditional medicine of many countries. Several flavonoides are identified from the plant material. Aerial parts which collected from northeast of Iran are used in this study. Three flavonoid glycosides were isolated and characterized. The flovonoids were found to be based on quercetin...
متن کاملFlavonoid glycosides from Cassia alata.
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.
متن کاملFlavonoid glycosides from Botrychium ternatum.
The MeOH extract from dried whole Botrychium ternatum plants yielded 33 compounds, including seventeen new flavonoid glycosides and sixteen known compounds. The structures of new compounds were established using NMR spectroscopic analysis and chemical evidence.
