Popis: A new rhamnofolane-type diterpenoid (1) and a new phenolic derivative (2), together with eleven known compounds, were isolated from the leaves of E. cochinchinensis Lour. The chemical structures of these compounds were elucidated based on extensive spectroscopic analysis, including HR-QTOF-MS and NMR, and comparison with reported data. The inhibitory effects of compounds 1–13 on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.7 cells were evaluated. As the obtained results, compound 9 showed a moderate inhibitory effects on NO production activity with an IC50 of 6.17 ± 0.25 µM, relative to that of the positive control cardamonin.
