【摘要】 从叶下珠中分离得到 6个化合物 ,根据理化数据和光谱方法鉴定为短叶苏木酚酸乙酯(1)、短叶苏木酚 (2 )、柯里拉京 (3)、原儿茶酸 (4 )、没食子酸 (5 )和鞣花酸 (6 ) .其中 (1)、(3)、(4 )为本种植物中首次分离 .根据 2D NMR修正了文献中化合物 (1)和 (2 )的部分碳信号归属错误 ,归属了化合物 (3)的碳氢谱数据更多还原

【Abstract】 Six compounds were isolated from the whole herb of Phyllanthus urinaria L..On the basis of physical and chemical properties and spectra data,they were identified as ethyl brevifolincarboxylate(1),brevifolin(2),corilagin(3),protocatechuic acid(4),gallic acid(5),ellagic acid(6).Compounds(1),(3)and(4)were isolated from this plant for the first time.The carbon assignment of compound(1)and(2)in literature were corrected by the use of 2D NMR.更多还原
