Abstract

From the leaves of Alangium paltanifolium var. platanifolium, collected in Fukuoka Prefecture, twelve further megastigmane glycosides were isolated. Seven of them, named platanionosides D-J (1-7), were found to be new compounds. Their structures were elucidated from spectroscopic evidence and their absolute structures were determined from beta-D-glucosylation-induced shift trends of 13C-NMR and by application of a modified Mosher's method.

摘要

从采自福冈县的宽叶八角枫(Alangium paltanifolium var. platanifolium)叶片中,又分离出了12种巨大戟烷型糖苷。其中7种被命名为八角枫苷D-J(1-7),发现它们是新化合物。通过光谱数据阐明了它们的结构,并根据β-D-葡萄糖基化诱导的13C-NMR位移趋势以及应用改良的莫舍尔方法确定了它们的绝对构型。
