目的研究大接骨丹Torricellia angulata根皮的化学成分。方法对大接骨丹95%乙醇提取物的醋酸乙酯部位进行色谱分离,通过波谱分析或直接与对照品对照进行结构鉴定。结果分离得到13个化合物,分别鉴定为β-谷甾醇(Ⅰ)、7-羟基-6-甲氧基香豆素(Ⅱ)、硬脂酸(Ⅲ)、软脂酸(Ⅳ)、syringoylglycerol(Ⅴ)、2H-1-benzopyr-an-2-one(Ⅵ)、3,5-二甲氧基苯甲醛(Ⅶ)、β-胡萝卜苷(Ⅷ)、9H-pyrano[2,3-f]-1,4-benzodioxin-9-one(Ⅸ)、(E)-对甲基苯丙烯醛(Ⅹ)、7-羰基-β-胡萝卜苷(Ⅺ)、邻,对-二甲氧基苯甲酸(ⅩⅡ)、10-griselinosidic acid(ⅩⅢ)。结论化合物Ⅱ、Ⅴ~Ⅶ、Ⅸ~ⅩⅡ为首次从该植物中分离得到,化合物Ⅴ、Ⅵ、Ⅸ为首次从鞘柄木属植物中分离得到。
Objective To study the chemical constituents of the root bark of Torlocella angulata. Methods The chromatographic separation of the ethyl acetate fraction of Daegudan 95% ethanol extract was performed. The structure was identified by spectral analysis or direct comparison with the reference substance. As a result, 13 compounds were isolated and identified as β-sitosterol (I), 7-hydroxy-6-methoxycoumarin (II), stearic acid (III), palmitic acid (IV), syringoylglycerol ( V), 2H-1-benzopyr-an-2-one (VI), 3,5-dimethoxybenzaldehyde (VII), β-carotene (VIII), 9H-pyrano [2,3-f] -1,4-benzodioxin-9-one(IX), (E)-p-methyl-benzenepropenal (X), 7-carbonyl-β-glucoside (XI), o,p-dimethoxybenzoate (XII), 10-griselinosidic acid (XIII). Conclusion Compounds II, V~VII and IX~XII were isolated from this plant for the first time. Compounds V, VI and IX were isolated from the plants of the genus Shelasium for the first time.
