Determination of Some Phenolic Compounds from Commercial Wine Vinegar Samples in Turkey by High Performance Liquid Chromatography
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.
