Five new 5,11-epoxyguaiane sesquiterpenes (1–5), along with a known one (6) were isolated from high quality agarwood ‘Qi-Nan’ originating from Aquilaria sinensis. Their structures were established based on spectroscopic methods including IR, HR-ESI-MS, 1D, and 2D NMR. Compounds 1–6 were all 5,11-epoxyguaiane sesquiterpenes, sharing the same tetrahydrofuran ring by etherification of C-5 and C-11, and...
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, 7β-H-9(10)-ene-11,12-epoxy-8-oxoeremophilane (2), 7α-H-9(10)-ene-11,12-epoxy-8-oxoeremophilane (3), neopetasane (4). Among them, compounds 1–3 were new...
