Abstract
(8S,8'R,9S)-, (8R,8'R,9R)-, and (8R,8'R,9S)-cubebins, together with (8R,8'R,8''R,8'''R,9R,9''S)-bicubebin, were isolated from Aristolochia lagesiana and Aristolochia pubescens. Their structures were determined by spectroscopic methods, including 1H and 13C NMR spectroscopy at low temperatures, and by chemical transformations.
摘要
从大叶马兜铃和毛马兜铃中分离得到了（8S，8'R，9S）-、（8R，8'R，9R）-和（8R，8'R，9S）-荜澄茄素，以及（8R，8'R，8''R，8'''R，9R，9''S）-双荜澄茄素。它们的结构通过光谱方法确定，包括低温下的1H和13C核磁共振光谱，以及化学转化。
