DEVELOPMENT OF A ROTATORY AND CONTINUOUS LIQUID-LIQUID EXTRACTION TECHNIQUE FOR PHENOLIC COMPOUNDS IN WINE

摘要

A liquid-liquid technique for extracting phenolic compounds of low molecular mass from wine, by means of a rotary system with diethyl ether, permitting the simultaneous extraction of up to 12 samples, is described. This technique permits the simultaneous extraction of several samples with good recoveries and high reproducibility, while at the same time minimizing the appearance of analytical artifacts during the process of extraction.
