Abstract
From seeds of Strychnos nux-vomica three iridoids, 6'-O-acetylloganic acid, 4'-O-acetylloganic acid and 3'-O-acetylloganic acid were isolated together with two known iridoid glucosides, loganic acid and 7-O-acetylloganic acid. The structures of the compounds were established by ESI-MS and by 1D and 2D NMR spectroscopic methods.
摘要
从马钱子种子中分离出三种环烯醚萜类化合物，6'-O-乙酰基哈帕苷、4'-O-乙酰基哈帕苷和3'-O-乙酰基哈帕苷，同时还分离出两种已知的环烯醚萜苷，哈帕苷和7-O-乙酰基哈帕苷。通过电喷雾电离质谱（ESI-MS）以及一维和二维核磁共振光谱方法确定了这些化合物的结构。
