摘　　要：利用硅胶和凝胶柱层析等方法对日香桂的化学成分进行了研究。从日香桂根的95%乙醇提取物中分离出7个单体化合物,分别为β-胡萝卜苷(1),连翘脂素(2),大黄酚(3),大黄素甲醚(4),β-谷甾醇(5),β-谷甾酮(6)和2-(4-羟基苯基)乙酸乙酯(7),其结构经1H NMR和13C NMR确证。2～4,6和7为首次从日香桂中发现;2为首次从该属中发现;3和4为首次从该科中发现。The chemical components of the roots of Osmanthus fragrans ＇ Rixianggui＇ were investiga- ted by the silica gel and Sephadex LH-20 column chromatography method. Seven compounds[β-dau- costerine （ 1 ）, phillygenin （2）, chrysophanol （3）, physeion （4）,β-sitosterol （5）,β-sitosterone （6）, and 2-（4-hydroxylphenyl）ethyl acetate （7） ] were obtained from the 95 % ethanol extract of the roots of the title plant. The structures were confirmed by 1H NMR and 13 ^C NMR. 2 - 4, 6 and 7 were isolated for the first time from this plant. 2 was isolated from this genus, and 3 and 4 from Oleaceae family for the first time.
