CANO, Arturo; ESPINOZA, Marina; RAMOS, Clara H.  and  DELGADO, Guillermo. New Prenylated Flavanones from Esenbeckia berlandieri ssp. acapulcensis. J. Mex. Chem. Soc [online]. 2006, vol.50, n.2, pp.71-75. ISSN 1870-249X.

Three new (1-3) and four known prenylated flavanones as well as friedelin were isolated from the aerial parts of Esenbeckia berlandieri ssp acapulcensis (Rutaceae). The structures of the new compounds were elucidated as 5,7-dihydroxy-8-(2,3-epoxy-3-methyl-butyl)flavanone (1), 5,4'-dihydroxy-7-methoxy-8-(2,3-dihydroxy-3-methylbutyl)flavanone (2), and 5,7,4'-trihydroxy-8-(2,3-dihydroxy-3-methylbutyl)flavanone (3). The isolated flavanones possess diferentially functionalized isoprene units at C-8, and this is the first report of flavanones isolated from Esenbeckia species.

Keywords : Esenbeckia berlandieri ssp. acapulcensis; Rutaceae; prenylflavanones.
