Abstract :Hawthorn fruit, known for its wide range of varieties, exhibits various biological activities. Its numerous therapeutic effects are largely attributed to its bioactive compounds. This study aimed to determine the total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity (via ABTS, DPPH, and FRAP assays), selected phenolic compounds, and physicochemical properties of commercial hawthorn vinegars sold in Türkiye. With the exception of one brand, all samples exhibited titratable acidity values below the acceptable limit. TPC and TFC values ranged from 86.21 to 456.42 mg GAE/L and 48.46 to 376.92 mg QE/L, respectively. Antioxidant activity values for ABTS, DPPH, and FRAP assays ranged from 111.00-722.18 mg TE/L, 36.90-381.80 mg TE/L, and 65.15-441.07 mg TE/L, respectively. Among the individual phenolic compounds identified, protocatechuic acid was the most abundant, followed by quercetin 3-β-D-glucoside, and vitexin was not detected in any vinegar sample. The study indicated that commercially available hawthorn vinegars might demonstrate significant variability in their physicochemical and bioactive properties.
