摘要


利用硅胶柱色谱、凝胶柱色谱、MCI柱色谱对滇南风吹楠70%(体积分数)丙酮提取物进行分离纯化,并通过1H NMR 、13C NMR 等波谱技术进行结构鉴定,从该提取物中共分离鉴定了6个化合物,包括4个木脂素和2个甾体类化合物,它们分别为dextrobursehernin (1), (2R,3S,4R)-2-(3,4-dimethoxyphenyl)-4-(4-hydroxy-3-methoxybenzyl)-3-hydroxymethyltetrahydrofuran (2), (2R,3S,4R)-4-(3,4-dimethoxy-benzyl)-2-(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyltetrahydrofuran (3), 4,4’-dimethylsecoisolariciresinol (4), 胡萝卜苷(5)和β-谷甾醇(6).化合物1~5均数首次从该植物中分离得到. This research focused on the chemical constituents of Horsfieldia tetratepala. From the 70% acetone extract, six compounds were separated and purified by the column chromatography. Their structures were elucidated by the means of spectroscopic analysis.These compounds were identified as dextrobursehernin (1), (2R,3S,4R)-2-(3,4-dimethoxyphenyl)-4-(4-hydroxy-3-methoxy-benzyl)-3-hydroxymethyltetrahydrofuran (2), (2R,3S,4R)-4-(3,4-dimethoxybenzyl)-2 -(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyltetrahydrofuran (3), 4,4'-dimethylse-coisolariciresinol (4), daucossterol (5), and β-sitosterol (6).Compoun 1-5 were obtained faom Honsfiedia tetnatepala for the finst time.
