Bioassay-directed fractionation of a methylene chloride extract of the root bark of Erythrina eriotricha resulted in the isolation of a novel isoflavanone, named eriotrichin B, and the five known pterocarpans, isonorautenol, erybraedin A, erybraedin C, erybraedin D and erybraedin E. The structure of the new compound has been investigated by extensive spectroscopic studies, including 2D NMR and chemical
Erythrina eriotricha 根皮的二氯甲烷提取物的生物测定定向分馏导致分离出一种名为 eriotrichin B 的新型异黄酮,以及五种已知的翼果树,即异紫苏烯醇、erybraedin A、erybraedin C、erybraedin D 和 erybraedin E。新化合物的结构已经通过广泛的光谱研究进行了研究,包括 2D 核磁共振和化学证据。还报告了分离化合物的体外抗菌谱和效力。
