Phytochemical investigation of an extract of the rhizome of Curcuma longa L., resulted in the identification of four undescribed bisabolane sesquiterpenoids, namely as bisacurone D-G (1-4). With the aid of comprehensive spectroscopic techniques (NMR, IR, UV, MS), the structures of all isolated compounds were elucidated and subsequently screened for both anti-inflammatory and cytotoxic biological activities, Compounds 1 and 2 showed moderate inhibitory activity toward LPS-induced NO production on RAW 264.7 macrophages.
