ABSTRACT

Do extrato hidroetanólico das partes aéreas de Acanthospermum australe (Asteraceae) foram identificados uma lactona diterpênica, o acetato de acantoaustralida (1) e dois flavonoides: quercetina (2) e crisosplenol D (3). As estruturas foram identificadas através de técnicas espectroscópicas de RMN de ¹H e 13C, gHSQC, gHMBC, TOCSY, gNOESY, EM e pela comparação com dados da literatura.


From the hydroethanolic extract of the aerial parts of Acanthospermum australe (Asteraceae) a diterpene lactone, acanthoaustralide-1-O-Acetate (1) and two flavonoids: quercetin (2) and chrysosplenol D (3) were identified. The structures were determined though the use of spectroscopic techniques such as NMR (¹H, 13C{¹H}, gHSQC, gHMBC, TOCSY, gNOESY), MS and compared with the literature data.
