Studies in Cell Suspension Cultures of Cassia didymobotrya. Part VI. The Biotransformation of Chalcones to Aurones and Auronols

Abstract

Cell-free extracts derived from tissue cultures of Cassia didymobotrya, which previously had been reported to convert 4-hydroxychalcones to flavones and biflavanones, catalyze the biotransformation of 2-hydroxychalcones to aurones and auronols. The aurone was shown to be the direct precursor of auronol.
