Sus estructuras químicas fueron determinadas por métodos espectroscópicos de NMR, ATR-IR y HRMS. Los compuestos aislados son: 5,7,4'-trihidroxiflavanona (1), 5,7-dihidroxi-4'-metoxiflavanona (2), 5-hidroxi-4',7-dimetoxiflavanona (3), 5,7,4'-trihidroxiflavonol (4), 5,7-dihidroxi-4'-metoxiflavonol (5) y 5,7-dihidroxi-4'-metoxiflavonoide (6), estos son reportados en Baccharis polycephala por primera vezSix flavonoids were obtained in a phytochemical investigation of the aerial parts of Baccharis polycephala. The structures of the natural products were established by NMR, ATR-IR spectroscopy and high resolution mass spectroscopy as 5,7,4'-trihydroxyflavanone (1), 5,7-dihydroxy-4'-methoxyflavanone (2), 5-hydroxy-4',7-dimethoxyflavanone (3), 5,7,4'-trihydroxyflavonol (4), 5,7-dihydroxy-4'-methoxyflavonol (5) and 5,7-dihydroxy-4'-methoxyflavone (6). The presence of the isolated compounds in Baccharis polycephala is reported for the first timeenFlavonoid, Baccharispolycephala Weddell5,7,4'-trihydroxyflavanone5,7-dihydroxy4'-methoxyflavanone5-hydroxy-4'7-dimethoxyflavanone5,7,4'-trihydroxyflavonol5-7-dihydroxy4'-methoxyflavonol5,7-dihydroxy4 '-methoxyflavoneArtículo Científico Publicado
