From the flowers of Laseguea erecta were isolated the lupeol, ursolic acid, quercetin (3,5,7,3',4'-pentahydroxyflavone) and 3-O-ß-L-arabinopyranosylquercetin. This is the first phytochemical study of this genera flowers'. The structures were established by the IR, 1H and 13C NMR (1D, 2D) spectral data analysis and by comparison with literature data.
