The following flavonoid compounds have been isolated and identified from flowers of Urena lobata L.: kaempferol 3-O-(6-O-trans-p-coumaroyl)-β-glucoside (tiliroside), dihydrokaempferol 4'-O-β-glucopyranoside, kaempferol and quercetin 3-O-β-glucosides and 3-O-β-rutinosides also luteolin 4'-O-β-glucopyranoside. Their structures were established by conventional (acid, enzymatic and alkaline hydrolysis) and spectral analysis (UV, 1H NMR, 13C NMR). Chromatographical investigations indicated the presence of quercetin, kaempferol and kaempferol 7-O-glucoside.
