Abstract
Naringin is selectively cleaved into L-rhamnose and naringenin-t-7-glucoside by heating naringin in solution under particular conditions of acid hydrolysis. Upon cooling the reaction medium, a liquid phase containing L-rhamnose and a semi-solid phase containing naringenin-7-O-glucoside are obtained from which those compounds may be isolated.
