BAUTISTA, Elihú; CALZADA, Fernando; ORTEGA, Alfredo  and  YEPEZ-MULIA, Lilian. Antiprotozoal Activity of Flavonoids Isolated from Mimosa tenuiflora (Fabaceae-Mimosoideae). J. Mex. Chem. Soc [online]. 2011, vol.55, n.4, pp.251-253. ISSN 1870-249X.

As result of the chemical study of the leaves and flowers of Mimosa tenuiflora (Willd.) Poir. (Fabaceae-Mimosoideae) eigth flavonoids were isolated: 6-methoxy-4'-O-methylnaringenin (1), santin (2), 6-methoxynaringenin (3), tenuiflorin A (4), 5, 7, 4'-trihydroxy-3, 6-dimethoxyflavone (5), 6-demethoxy-4'-O-methylcapilarisine (6), 6-methoxykaempferol (7) and tenuiflorin C (8). Antiprotozoal activity of these compounds as well as the tenuiflorina B (9) and 6-desmethoxy-capilarisine (10), isolated in a previous study was assessed against Entamoeba histolytica and Giardia lamblia trophozoites.

Keywords : Mimosa tenuiflora; Fabaceae; flavonoids; 2-phenoxycromones; antiprotozoal activity; tepescohuite.
