摘要： 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-hydroxylbaimuxinol (1) and three eremophilanes, 7 beta-H-9(10)-ene-11,12-epoxy-8-oxoeremophilane (2), 7 alpha-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 mu M, respectively. (C) 2014 Phytochemical Society of Europe.
