From the leaves of Zanthoxylum ailanthoides, 4'-O-p-E-coumaric acid esters of 2-propanol β-D-glucopyranoside, megastigmane and megastigmane glucosides were isolated. Their structures were elucidated by spectroscopic evidence. The absolute configurations of the megastigmane and aglycone of megastigmane glucosides were determined by the octant rule and modified Mosher's method after protection of carboxylic
从花椒中分离出2-丙醇β-D-吡喃葡萄糖苷,大麦角菜碱和大麦角石碱葡糖苷的4'-OpE-香豆酸酯。光谱证据阐明了它们的结构。在通过对-溴苯甲酰基酯保护羧酸和通过新戊酰基酯保护伯醇之后,通过辛酸规则和改进的Mosher方法确定了巨大柱头糖苷的巨大柱头糖苷和糖苷配基的绝对构型。
