Abstract

From the acetone extract of the roots of Derris trifoliata an isoflavonoid derivative, named 7a-O-methyldeguelol, a modified rotenoid with an open ring-C, representing a new sub-class of isoflavonoids (the sub-class is here named as rotenoloid), was isolated and characterised. In addition, the known rotenoids, rotenone, deguelin and alpha-toxicarol, were identified. The structures were determined on the basis of spectroscopic evidence. Rotenone and deguelin were identified as the larvicidal principles of the acetone extract of the roots of Derris trifoliata.

摘要

从三叶鱼藤根的丙酮提取物中分离并鉴定出一种异黄酮衍生物，名为7a - O - 甲基鱼藤醇，它是一种具有开环C的修饰鱼藤酮类化合物，代表了异黄酮类的一个新亚类（该亚类在此命名为鱼藤醇类）。此外，还鉴定出了已知的鱼藤酮类化合物鱼藤酮、鱼藤素和α - 毒灰叶酚。结构是根据光谱证据确定的。鱼藤酮和鱼藤素被确定为三叶鱼藤根丙酮提取物的杀幼虫成分。
