(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 H-1 and C-13 NMR spectroscopy at low temperatures, and by chemical transformations. (c) 2006 Elsevier Ltd. All rights reserved.
从马兜铃 Aristolochia lagesiana 和 Aristolochia pubescens 中分离获得 (8S,8'R,9S)-、(8R,8'R,9R)- 和 (8R,8',R,9S)-卡波比 compounds,以及 (8R,8'R,8"R,8'''R,9R,9"S)-双卡波比。这些化合物的结构通过光谱学方法(包括低温下的 ¹H 和 ¹³C 核磁共振光谱)和化学转化得以确定。© 2006 汉姆斯有限公司。版权所有。
