A new chlorinated 11-noreremophilane-Type sesquiterpene (1) together with 3-epiisopetasol, PR-Amide and mycophenolic acid (2-4) were isolated from endophytic fungus Penicillium citreonigrum. The structures of 1-4 were elucidated by a combination of spectroscopic data and single-crystal X-ray diffraction analysis. Among them, compounds 1 and 4 showed moderate antioxidant capacities compared with ascorbic acid at 0.2 mM concentration.
