A new flavone C-glycoside from Clematis rehderiana.
A new flavone C-glycoside, isovitexin 6''-O-E-p-coumarate (1) and two known flavonoid glycosides--quercetin 3-O-beta-D-glucuronopyranoside (2) and isoorientin (3)--were isolated from an ethanol extract of aerial parts of Clematis rehderiana. Their structures were determined by spectroscopic methods. The antioxidant effects of the two flavone C-glycosides were evaluated by both the MTT and DPPH ...
متن کاملFlavone glycoside from the roots of Fironia limonia
From the water insoluble part of alcoholic extract of the roots of Feronia limonia a new flavone glycoside has been isolated. On the basis of U.V, I.R, N.M.R (1H, 13C) and mass spectral studies the compound was characterized as 5,4'-dihydroxy-7-methoxyflavone-8-O-β-Dglucopyranoside
متن کاملStudies on the localization of the cardiac glycoside receptor.
The purpose of this study was to see whether the receptor for cardiac glycosides might be localized upon or within the plasma membrane of digitalis-sensitive cells. Ouabain and digoxin were joined covalently to several large protein molecules. These macromolecular conjugates are too large to enter intact cells; consequently, any pharmacologic or biochemical effects which they display should ari...
متن کاملA new flavone O-glycoside and other constituents from wheat leaves (Triticum aestivum L.).
From leaves of Triticum aestivum a new O-glycosylflavone has been isolated together with chlorogenic acid and its 3'-methyl ether and 6 C-glycosylflavones. The structure of the new flavonoid was determined by 1D and 2D NMR techniques and other spectral evidence as 5,7-dihydroxy-3',4',5'-trimethoxyflavone-7-O-beta-rutinoside.
متن کاملA new hepatoprotective flavone glycoside from the flowers of Onopordum alexandrinum growing in Egypt.
A bioactivity-guided fractionation of the ethyl acetate fraction of the flowers of Onopordum alexandrinum L. (Asteraceae) yielded a new flavonoidal glycoside designated as acacetin-7-O-galacturonide (9), alongside with nine known flavonoids; 6-methoxy-apigenin (hispidulin) (1), acacetin (2), apigenin (3), luteolin (4), kaempferol (5), eriodictyol (6), apigenin-7-O-glucoside (7), luteolin-7-O-gl...
