从采自冲绳的桃金娘（Myrsineseguinii）叶中分离得到8个大豆甾烷苷类化合物。其中三种是已知化合物，即，蛇葡萄苷、八角枫苷J和柳松苷A。新的megastigmane糖苷的结构从光谱数据进行了阐明，并确定了其绝对立体化学的详细使用修改的Mosher的方法。
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.
