Abstract

From the stem bark of Erythrina eriotriocha, a novel isoflavone, eriotriochin has been isolated and characterized, in addition to known compounds auriculatin, dihydroauriculatin, and 3'-O-methylorobol. The structure of compound 1 was determined by COSY, selective INEPT, 2D HMBC, NOESY, DEPT, and other spectroscopic techniques.
