Popis:	This the first phytochemical investigation of Mimosa artemisiana (Leguminosae-Mimosoideae) describing the isolation and identification of quercitrin, myricitrin, 3,5,4´-trihydroxi-6,7-dimethoxyflavone (6,7-dimethylkaepferol), flavolignans, 3-O-β-D-glucopyranosil sitosterol, lupeol, sitostenone, stigmastenone, campestenone, sitosterol, stigmasterol, campesterol, methyl indole-3-carboxilate and indole-3-carboxaldehyde in the extracts from the leaves and wood of this plant. This is the first registry of 6,7-dimethoxy,4'-hydroxy-flavona and the flavonolignans in this genera. The isolation of all metabolites was made by chromatographic methods and the structures were established on the basis of IR, MS, ¹H and 13C NMR spectra analysis, comparison with literature data and GC-MS of mixtures analysis.
