          Abstract

          Augusta has traditionally been placed in the tribe Rondeletieae, subfamily Cinchonoideae. However, recent molecular phylogenies positioned it near to Wendlandia (Ixoroideae), but locate A. longifolia near to the clade Ixoroidinae II. The study of A. longifolia afforded two coumarins, five flavonoids, three triterpenoids and one benzoic acid derivative. These metabolites reinforce the separation of Augusta as a monospecific genus, and Lindenia as a genus of three species, closely related to Wendlandia.

          Augusta tem sido tradicionalmente colocada na tribo Rondeletieae, Cinchonoideae subfamília. No entanto, recentes filogenias moleculares posicionou-a perto de Wendlandia, porém localizando A. longifolia perto do clado Ixoroidinae II. O estudo de A. longifolia resultou em duas cumarinas, cinco flavonoides, três triterpenoides e um derivado do ácido benzóico. Estes metabolitos reforçam a separação da Augusta como um gênero monoespecífico, e Lindenia como um gênero de três espécies, intimamente relacionada com Wendlandia.
