Implicações químicas na sistemática e filogenia de bignoniaceae

Abstract

Our solemn homage to the great Master Otto R. Gottlieb who knew how to teach the mystery of evolutionary relationships between chemistry and its natural sources. The micromolecular chemical study of the family Bignoniaceae shows a profile predominantly characterized by the occurrence of metabolites derived from acetic acid biosynthetic pathways such as terpenoids, quinones, flavonoids and special aromatic derivatives. Analysis of different chemosystematic parameters for the metabolite data collected, provided valuable information for the systematic characterization of the Bignoniaceae family within the Angiosperm derived taxa.
