The alkaline hydrolysis of flavonoid glycosides
Chemistry of Natural Compounds, 19691. The alkaline hydrolysis of flavonoid glycosides has been studied. 2. In an alkaline medium 3-glycosides, C-glycosides, and biosides having 1, 2 bonds between the sugars are stable. 3. The difference in the stabilities of the glycosides to alkalis can be used in studying flavonoid O-diglycosides, O-biosides with different positions of the bond, O,C ...

Thermal Degradation of Glycosides, IV. Degradation of flavonoid glycosides
Liebigs Annalen der Chemie, 1991AbstractBy mere heating, the flavone (1, 7), flavanone (4, 10), and flavonol glycosides (13, 14) are converted into their aglycones and monoglycosides. The products of pyrolysis have been isolated by chromatography and their structures elucidated by chemical and spectroscopic methods.

Anti-platelet effects of flavonoids and flavonoid-glycosides from Sophora japonica
Archives of Pharmacal Research, 2008A methanol extract of Sophora japonica was subjected to anti-platelet activity guided fractionation affording the isolation of four flavonoids and six flavonoid-glycosides: biochanin A (1), irisolidone (2), genistein (3), sissotrin (4), sophorabioside (5), genistin (6), tectoridin (7), apigenin (8), quercitrin (9), and rutin (10). The structure of each

The use of flavonoid glycosides for the identification of elm hybrids
Canadian Journal of Forest Research, 1993The utilization of elm leaf flavonoids as biochemical markers for the identification of artificial and natural hybrids of elm species is discussed. Two to 11 individuals from controlled crosses of Ulmuscarpinifolia Gled., Ulmuspumila L., Ulmusparvifolia Jacq., and Ulmusjaponica (R.) Sarg. were examined.

Acylated flavonoid glycosides from Bassia muricata
Phytochemistry, 2001From 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-

Flavonoid glycosides from Salvia moorcroftiana Wall.
Carbohydrate Research, 2002Phytochemical 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, 2010Oxidative 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).

Flavonoid Glycosides fromAlchemilla speciosa
Planta Medica, 1999The new flavonol glycosides quercetin 3- O-beta-(2''- O-alpha- L-rhamnopyranosyl)-glucopyranoside uronic acid and kaempferol 3- O-beta-(2''- O-alpha- L-rhamnopyranosyl)-glucopyranoside uronic acid were isolated from the leaves of Alchemilla speciosa Buser together with 13 known flavonol and flavone glycosides and (+)-catechin.
