【 摘 要 】

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.
