Phytochemical analysis of the high quality Chinese agarwood Qi-Nan originating from Aquilaria sinensis (Lour.) Glig, led to the isolation of four fragrant sesquiterpenes, including an agarofuran 4-hydroxyl-baimuxinol (1) and three eremophilanes,7b-H-9(10)-ene-11,12-epoxy-8-oxoeremophilane (2), 7a-H-9(10)-ene-11,12-epoxy-8-oxoeremophilane (3), neopetasane (4).Among them, compounds 1-3 were new compounds.Their structures were elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR) and MS analyses.Eremophilane sesquiterpenes 2-4 showed inhibitory activities against acetylcholinesterase with IC50 value of 274.8, 491.4, and 158.3 mM, respectively.
