Six new dimeric 2-(2-phenylethyl)chromones (1-6) were isolated from the EtOAc extract of artificial agarwood originating from Aquilaria sinensis (Lour.) Glig. Their structures were unambiguously elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR), and HRESIMS analysis, as well as by comparison with the literature. The absolute configurations were determined by ECD spectra.
从人工沉香（Aquilaria sinensis (Lour.) Glig.）中分离得到的乙酸乙酯提取物中分离得到了六个新的二聚 2-(2-苯乙基)色酮（1-6）。通过光谱技术（UV、IR、1D 和 2D NMR）、高分辨率质谱分析以及与文献的比较，明确了它们的结构，并通过 ECD 光谱确定了它们的绝对构型。
