Abstract
A reverse phase high performance liquid chromatography (HPLC) method for quantitative determination of
tartaric, malic, shikimic, lactic, citric and succinic acids in wines has been validated after the sample clean up.
The method was optimized using Supelco LiChrosorb RP-18 (250x4.6mm,5μm) column showing best
performance on selectivity between the malic and shikimic acids. Validation parameters such as linearity, limit
of detection (LOD), limit of quantification (LOQ), precision and recovery of the method, after clean up of the
wine samples through C18 solid phase extraction (SPE) columns, were determined. The validated method was
applied for analysis of several white and red wines from Macedonian origin.
