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 (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 (from 0.01 to 0.02 mg L^{− 1})
and limit of quantifications, LOQs (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.
