the hptlc analysis, antioxidant, and antigout activity of asparagus racemosus, withania somnifera, vitex negundo, plumbago zeylanica, butea monosperma and tephrosia purpurea extracts were investigated. the chemical fingerprinting were carried out by high performance thin layer chromatography (hptlc), antioxidant activity by abts, dpph, frap radical scavenging assays, and antiogout activity by c...

allopurinol, the xanthine oxidase inhibitor, is the only drug available for the treatment of gout. we examined the xanthine oxidase inhibitory activity of some commercially available flavonoids such asepigallocatechin, acacatechin, myricetin, naringenin, daidzein and glycitein by virtual screening and in-vitro studies. the interacting residues within the complex model and their contact types we...

Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

flavonoids could serve as potent inhibitors of xanthine oxidase (xo). in the present study, the effects of ruta graveolens l. extract and its major isolated flavonoids, quercetin and rutin, on guinea pig liver xo have been investigated. the inhibitory effects of r. graveolens, quercetin and its glycoside form, rutin, were assayed spectrophotometrically. r. graveolens extract showed moderate inh...

That flavonoids inhibit xanthine oxidase from cow milk was confirmed by measuring oxygen consumption with an oxygen electrode. In contrast, flavonoids did not inhibit glucose oxidase, another oxygen consuming enzyme. Among the flavonoids tested, quercetin, kaempferol, myricetin, chrysin, quercitrin, and morin were potent inhibitors of xanthine oxidase; their inhibition rates (%) were 80, 70, 69...

An attempt has been made to search for xanthine oxidase (XO) inhibitors from the root extracts of Tephrosia purpurea Linn. which is traditionally used in folk medicine in India. Root extracts were screened for in vitro antioxidant and xanthine oxidase inhibitory activity. Antioxidant activity was measured using ABTS, DPPH, FRAP and ORAC methods. The enzyme inhibitory activity was tested on puri...
