Ninenewnorlabdanediterpenoids were isolated from the leaves of Austroeupatoriuminulifolium 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
