The study on sesquiterpenoids from a marine-derived fungus Phellinus sp. HN-22 led to the isolation and purifi- cation of a new sesquiterpene compound, (3S,6S,7S,10S)-tremulene-10,12-dihydroxy-11-ylacetate (1), and seven known sesquiterpenes derivatives, 6α-hydroxycinnamolide (2), 6β-hydroxycinnamolide (3), 3β-acetoxycinnamolide (4), Ceriponol D (5), 3β-hydroxycinnamolide (6), 2α,3β-dihydroxycinnamolide (7), and 3β,6β-dihydroxycinnamolide (8). The structure absolute configuration of the new compound was determined by high resolution electrospray ionization mass spectroscopy (HRESIMS), nuclear magnetic resonance (NMR) and electronic circular dichroism calculations (ECD) methods. Based on inhibiting effects of the production of inflammatory factor NO, compound 3 exhibited similar anti-inflammatory activity with a half maximal inhibitory concentration (IC50) value of (27.78±0.04) μmol/L as that of the positive control, dexamethasone (IC50=(32.56±0.34 μmol/L)).

Key words: marine-derived fungi, tremulane-type sesquiterpenes, drimane-type sesquiterpenes, separation and identification, anti-inflammatory activities
