摘要： Two unprecedented 2-(2-phenethyl)chromone derivatives, 4 '-demethoxy-aquisinenin I (1) and 6"-methoxycrassna B (2),together with a known 2-(2-phenylethyl)chromone dimer (3), were isolated from the ethanol extract of agarwood of Aquilaria crassna. Their structures were constructed through comprehensive spectroscopic analysis, including 1D and 2D NMR, HRESIMS. All compounds were screened for their anti-Helicobacter pylori activity and ability to inhibit nitric oxide production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Compound 1 exhibited anti-Helicobacter pylori effect with a MIC value of 40 mu M, and anti-inflammatory activity with an IC50 value of 14.10 +/- 1.04 mu M.
