Sesquiterpenoids from the rhizome of Curcuma zedoaria

In the course of searching for biologically active sesquiterpenoids from Curcuma genus, two sesquiterpenoids were isolated from the rhizome of Curcuma zedoaria (Zingiberaceae). Their structures were identified as ar-turmerone (1) and beta-turmerone (2). The structure elucidation of compounds 1 and 2 was carried out by comparison of their physical and spectral data with previously reported values.
