Three 2-(2-phenylethyl) chromone derivatives were isolated from the ethyl acetate soluble fraction of the alcoholic extract of Aquilaria sinensis (Lous.) Gilg. (Thymeleaceae) by silica gel chromatography. Based on spectral data (UV, IR, 1HNMR, 13CNMR and MS) two of them are new compounds and their structures were identified as 5,8-dihydroxy-2-(2-p-methoxyphenylethyl) chromone (2) and 6,7-dimethoxy-2-(2-p-methoxyphenylethyl) chromone (3). The known compound siolated for the first time from this plant, was identified as 5,8-dihydroxy-2-(2-phenylethyl)-chromone (1).
通过硅胶柱色谱法，从白木香（瑞香科）乙醇提取物的乙酸乙酯可溶部分中分离出三种2-(2-苯乙基)色酮衍生物。基于光谱数据（紫外光谱、红外光谱、核磁共振氢谱、核磁共振碳谱和质谱），其中两种为新化合物，其结构被鉴定为5,8-二羟基-2-(2-对甲氧基苯乙基)色酮（2）和6,7-二甲氧基-2-(2-对甲氧基苯乙基)色酮（3）。首次从该植物中分离得到的已知化合物被鉴定为5,8-二羟基-2-(2-苯乙基)色酮（1）。
