The structure of the new compound was established by extensive analysis of mass spectrometric and 1D and 2D NMR spectroscopic data. Compound <b>1</b> showed moderate anti-inflammatory activities with IC<sub>50</sub> value of 8.12 μM. This is the first example of diterpenoids with 4-hydroxy-4-(2-hydroxyethyl)-1-hydroxyl-cyclohexanoyl substituent.</p> 2017-06-23 07:21:30 Eurya chinensis diterpene derivative anti-inflammatory
