摘要： Six 8,12-epoxyguaiane sesquiterpenes (1-6), together with two known 2-(2-phenylethyl)chromone derivatives (7-8) were isolated from agarwood originating from Aquilaria filaria. Their structures were established by spectroscopic methods including IR, HRESIMS, 1D, and 2D NMR, and comparison with the published data. The absolute configuration of compound 1 was unambiguously determined by quantum chemical calculation of the electronic circular dichroism (ECD) spectrum. All compounds were tested for their alpha-glucosidase inhibitory activity and cytotoxicity. Compound 5 showed significant alpha-glucosidase inhibitory activity with IC50 value of 253.2 +/- 9.7 mu M (Acarbose, 743. +/- 4 3.3 mu M). Compounds 2-4 displayed weak cytotoxicity against K562 tumor cell lines.
