From the leaves of Meliosma lepidota ssp. squamulata, megastigmane glucosides with spiro-structures and megastigmanes were isolated. Their structures were determined by X-ray crystallographic analyses and spectroscopic investigation. The absolute structures of the megastigmanes were determined by the modified Mosher’s method.
从 Meliosma lepidota ssp. squamulata 的叶子中分离出了具有螺旋结构的巨黄芪苷和巨黄芪。通过 X 射线晶体学分析和光谱研究确定了它们的结构。巨石苷的绝对结构是通过改进的莫舍尔法确定的。
