南天竹种子中酚酸类成分

Phenolic Acid Constituents in Seeds of Nandina domestica

摘要:

目的: 研究南天竹种子的化学成分. 方法: 采用正反相硅胶、凝胶、微孔树脂柱色谱,薄层色谱等手段分离,波谱法进行结构鉴定. 结果: 从南天竹种子中分离得到9个酚酸类化合物:丁香酸(1),没食子酸乙酯(2),鞣花酸(3),咖啡酸(4),对羟基苯甲酸(5),没食子酸(6),原儿茶酸(7),3,3'-二甲基鞣花酸-4-O-β-D-葡萄糖苷(8),岩白菜素(9). 结论: 化合物 1~9 均为在此植物中首次分离得到.

Abstract:

Objective: To study the chemical constituents of the seeds of Nandina domestica. Method: The compounds were isolated with column chromatography and their structures were elucidated by means of spectral analysis. Result: Nine phenolic compounds were isolated and their structures were identified as syringic acid(1), ethyl gallate(2), ellagic acid(3), caffeic acid(4), p-hydroxybenzoic acid(5), gallic acid(6), protocatechuic acid(7), 3,3'-di-O-methylellagic-4-O-β-D-glucoside(8), bergenin(9), respectively. Conclusion: The compounds 1-9 were first isolated in Nandina domestica.
