Flavonoid Glycosides from Byrsocarpus Coccineu (connaraceae)
The bioactive ethyl acetate and N-butanol soluble parts of an ethan leaves was subjected to column chromatography over silica gel G (60 120 flavonoid rich fraction over sephadex LH-20 eluted with methanol led to th identified as quercetin 3-O-α-arabinoside (I), quercetin(II) and quercetin 3elucidated by H and C-NMR data and are reported here for the first time
متن کاملPhysicochemical characterization of phyllanthin from Phyllanthus amarus Schum. et Thonn.
Phyllanthin is a major bioactive lignan component of Phyllanthus amarus, with several known biological activities. This study dealt with the isolation and physicochemical characterization of phyllanthin. Phyllanthin was isolated from P. amarus leaves by column chromatography and purified by recrystallization to obtain phyllanthin crystals with a purity of more than 98%. UV, IR, MS, (1)H NMR and...
متن کاملFlavonoid glycosides from the leaves of Cissus ibuensis hook (vitaceae).
The bioactive N-butanol fraction of the ethanol extract of the leaves of Cissus ibuensis was fractionated over silica Gel column to give Quercetin 3-O-rutinoside (I) and mixtures of Flavonoids (A2). A2 was fractionated using reverse phase HPLC to give Kaempferol 3-O-α-rhamnopyranosyl (1→6)-β-D-galactopyranoside (II), Kaempferol 3-O-rutinoside(III) and Kaempferol3-O-α-rhamnopyranosyl (1→6)-α-rha...
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...
