Thesuccess of Chilean wine in the international market has led to an importantattention on the development of science and technology for winedifferentiation, productivity, and quality. In order to report the profile ofphenolic acid compounds in Chilean red wines, an SPE technique over ODS columnwas used followed by a reverse phase HPLC program that was developed toseparate, characterize and quantify six phenolic acids (caffeic, gallic,p-coumaric, protocatechuic, syringic and vanillic acids) in four red Chileanwines varieties (Cabernet Sauvignon, Carménère, Merlot and Syrah) from grapescultivated in the central zone of Chile. The separation was carried out on anRP C-18 column using a binary gradient elution and diode array detection.
