摘要：

In addition to known compounds, sigmoidin C and 8-(3,3-dimethylallyl)-erythrinin C, also called senegalensin, a new isoflavone glycoside designated auriculatin 4'-O-glucoside was isolated from the chloroform extract of the stem bark of Erythrina eriotricha. Its structure was elucidated as 7,6-(2"',2"'-dimethyl-2 H-pyrano)-2',5-dihydroxy-8-(3,3-dimethylallyl)-isoflavone 4'-O-beta-D-glucoside on the basis of spectroscopic methods and chemical evidence.
