疏花卫矛化学成分的研究

Chemical Constituents from Barks of Euonymus laxiflorus Champ. ex Benth.

摘要:

从疏花卫矛(Euonymus laxiflorus Champ. ex Benth.)树皮的乙醇提取物中分离得到14个化合物, 通过波谱分析(NMR、MS、IR等), 鉴定其结构分别为:羽扇豆醇 (1)、木栓酮 (2)、羽扇豆酮 (3)、 3-羟基-4-甲氧基苯甲醛 (4)、东莨菪内酯 (5)、 (+)-松脂醇 (6)、(-)-Isoyatein (7)、4-羟基-3-甲氧基肉桂醛 (8)、京尼平苷酸 (9)、胆甾醇 (10)、(8R,8′R,9R)-cubebin (11)、(8R,8′R,9S)-cubebin (12)、 4-羟基-3,5-二甲氧基肉桂醛 (13)、二十六碳酸 (14)。化合物1~14均为首次从该植物中分离得到。

Abstract:

Fourteen compounds were isolated from ethanol extract of Euonymus laxiflorus Champ. ex Benth. barks. On the basis of spectral data (NMR, MS, IR, etc.), they were identified as lupeol (1), friedelin (2), lupine ketone (3), 3-hydroxy-4-methoxy-benzaldehyde (4), scopoletin (5), (+)-pinoresinol (6), (-)-isoyatein (7), coniferylaldehyde (8), geniposidic acid (9), cholesterol (10), (8R,8′R,9R)-cubebin (11), (8R,8′R,9S)-cubebin (12), 3,5-dimethoxy-4-hydroxycinnamicaldehyde (13), hexacosanic acid (14). All of compouds were isolated from the plant of E. laxiflorus for the first time.
