【摘要】 目的:对深绿山龙眼Helicianilagirica种子的化学成分进行研究。方法:采用乙醇提取,石油醚、二氯甲烷、正丁醇萃取,硅胶柱色谱分离,通过理化性质和光谱分析鉴定结构。结果:从二氯甲烷和正丁醇部分分离鉴定5个化合物:对羟基苯甲醛(1),对羟基苯甲酸(2),没食子酸(3),豆腐果苷(4),对甲醛基苯-O-β-D-吡喃葡萄糖苷(5)。结论:以上化合物除豆腐果苷外均为首次从该种植物中分离得到,化合物1,2,3为首次从山龙眼属植物中得到。更多还原

【Abstract】 Objective: To study the chemical constituents in seeds of Helicia nilagirica.Method: The ethanol extract was seperated by petroleum ether, dichloromethane, n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical properties and spectral analysis. Result: Five compounds were isolated from the dichloromethane and n-bu-tanol extracts, identified as p-hydroxybenzaldehyde (1) , p-hydroxybenzoic acid (2) , gallic acid (3) , helicide (4) , 4-formylpyrnyl-O-β-D-glucopyranoside (5) . Conclusion: All the compounds except Ⅳ were isolated from the plant for the first time. The compounds Ⅰ,Ⅱ and Ⅲ were isolated from the genus Helicia for the first time.更多还原
