摘要	A phytochemical investigation to obtain chemical components with potential anti-inflammatory activity from E. hylonoma led to the isolation of nine new ent-isopimarane diterpenoids (1 and 3-10), a new ent-rosane diterpenoid (11), along with eight known ones (2 and 12-18) using various chromatographic techniques. Compounds 3, 4, 5, and 10 were rare examples of the epoxy-ent-isopimarane. The structures of these new compounds were confirmed by extensive spectroscopic data, crystal X-ray diffraction analysis, and electronic circular dichroism. And the isolates were evaluated for their inhibitory effects on nitric oxide production induced by lipopolysaccharide in RAW 264.7 cells. The results showed that compounds 2 and 12 exhibited noteworthy inhibitory effects against NO production with IC50 values of 7.12 and 12.73 mu M, respectively, which were better than positive control (IC50 = 41.41 mu M). The possible mechanism that compounds 2 and 12 could inhibit NO production was investigated by the Western blotting experiments.
