%X n this work it is exposed the obtained results of the phytochemical study of the fresh leaves of Urena sinuata L. (dog wart). The major components are the flavonoids: quercetagetin-6,7-O-dimethylether-3'-¦Â-D-gluco-pyranoside (I), quercetagetin-6,7-O-dimethylether-4'-¦Â-D-glucopyranoside (II), and quercetagetin-6,7-O-dimethylether-3-¦Â-D-glucopyranoside (III). These products were characterized through their physical constants, UV, MS, and one- and two-dimensional NMR studies. By other hand, the obtained results of the Artemia salina cytotoxicity bioassay carried out to the isolated products are exposed.
