A new diterpenoid named jatrophacine (1), with an unusual 4,5-seco- rhamnofolane skeleton, was isolated from the roots of Jatropha curcas, together with eleven known diterpenoids. The structure of the new compound was elucidated through a detailed analysis of its 1 D- and 2 D-NMR spectra. The X-ray structure of jatrophol (2) is also presented. Anti-inflammatory activity with LPS-induced RAW 264.7 macrophages revealed that compound 1 strongly inhibited the production of nitric oxide (IC50 = 0.53 μM).
