- Abstract
Nine new norlabdane diterpenoids were isolated from the leaves of Austroeupatorium inulifolium collected in Indonesia. All of them have an acyl-furan unit connected to C(11), and oxygenated functions at C(2) and C(3). The structure elucidations and the assignment of the absolute configurations of the isolated natural products were carried out by extensive spectroscopic analysis and the extended Mosher method, as well as chemical correlations. Antimicrobial activities and cytotoxicity against HL-60 cells were determined using bioassays.
