Abstract
Eight megastigmane glycosides were isolated from the leaves of Myrsine seguinii collected in Okinawa. Three of them were found to be known compounds, i.e., ampelopsisionoside, alangionoside J, and linarionoside A. The structures of the new megastigmane glycosides were elucidated from the spectroscopic data and their absolute stereochemistries were determined in detail using a modified Mosher's method.
摘要
从冲绳采集的铁仔叶中分离出8种巨大戟烷糖苷。其中3种为已知化合物，即蛇葡萄素糖苷、八角枫糖苷J和亚麻糖苷A。通过光谱数据阐明了新巨大戟烷糖苷的结构，并使用改良的莫舍尔方法详细确定了它们的绝对立体化学结构。
