Beilschmiedia tovarensis fueron aisladas
e identificadas dos nuevas chalconas: 2’,
6’-dihidroxi-4’-isopenteniloxi-3,4(3”’,3””-dimetilpirano) chalcona y 4,2’, 6’-trihidroxi-3’, 4’ metilenodioxi-3-isopentenilchalcona.
El aislamiento y la purificación fueron realizados por técnicas cromatográficas.
La elucidación estructural de estos compuestos se determinó mediante técnicas espectroscópicas (IR,
RMN-1H, 13C y EM).
Además, fue probada la actividad biológica in vitro del extracto etanólico de madera, dando resultados significativos para actividad antimicrobiana en cepas Gram(+): Staphylococcus aureus y Enterococcus faecalis. Las pruebas de actividades antimalárica y antituberculosa dieron resultados negativos.
