Abstract

A new eudesmane-type sesquiterpenoid, hedytriol (1), was isolated from Hedychium yunnanense (Zingiberaceae). By means of chemical and spectroscopic methods, the structure of 1 was determined as ( - )-7aH-eudesmane-1beta, 4alpha, 11-triol. A new ent-eudesmane sesquiterpenoid, disciferitriol (2), was isolated from Porana discifera (Convolvulaceae), which was exactly the enantiomer of hedytriol (1). The structures of pterodondiol (3a) and pterodontriol B (3), previously isolated from Laggera pterodonta, were revised on the basis of X-ray diffraction, as well as chemical transformations.

摘要

从云南姜花（姜科）中分离出一种新的桉叶烷型倍半萜，滇姜花醇（1）。通过化学和光谱方法，确定1的结构为（-）-7aH-桉叶烷-1β，4α，11-三醇。从盘叶薯（旋花科）中分离出一种新的对映-桉叶烷倍半萜，盘叶薯醇（2），它与滇姜花醇（1）恰好是对映体。基于X射线衍射以及化学转化，对先前从翼齿六棱菊中分离得到的翼齿六棱菊二醇（3a）和翼齿六棱菊三醇B（3）的结构进行了修正。
