Abstract :Seven different commercial wine vinegars from Turkey were analyzed to verify the presence of phenolic compounds. A sensitive, simple and accurate method was developed to determine eight bioactive phenolic compounds insert ignore into journalissuearticles values(chlorgenic acid, caffeic acid, p-coumeric acid, rutin, ferullic acid, quercetin, naringenin, kaempferol);. Quantification and idendification of phenolic compounds was carried out by a validated HPLC–UV method. The analytical parameters were eveluated, establishing limit of detections, LODs insert ignore into journalissuearticles values(from 0.01 to 0.02 mg L − 1 ); and limit of quantifications, LOQs insert ignore into journalissuearticles values(from 0.03 to 0.06 mg L − 1 ); in the present method.The correlation coefficients were all above 0.998. The method was validated for specificity, linearity and precision.
