title: Auriculatin 4'-O-Glucoside: A New Prenylated Isoflavone Glycoside from Erythrina eriotricha1.
abstract: 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.
