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 Six compounds were isolated from the lower leaves of the leaves and identified as phytogenic data and spectral methods as ethyl short-leaf pyrophyll (1), short-leaved heparin (2), corilagin (3), protocatechuic acid (4) , Gallic acid (5) and ellagic acid (6). Among them, (1), (3), (4) are the first separation in the plant. According to 2D NMR, the compounds (1) and (2) in the literature are modified. Part of the carbon signal is incorrectly assigned and belongs to the hydrocarbon data of compound (3)
