HPLC study of the efficiency of extraction of phenolic compounds

The rate of extraction of phenolic compounds in two different solvents has been studied by liquid chromatography (HPLC) under reverse phase, gradient elution conditions. The solvents were diethyl ether and ethyl acetate. The method has been applied to two natural samples, a white wine and apple pulp.The authors acknowledge the financial support of the Comision Interministerial de Ciencia y Tecnologia (C.I.C.Y.T.).Peer reviewe
