Hawthorn (Crataegus spp.), a wild fruit whose consumption has increased in recent years, is abundant in Turkey’s ecology. This fruit is particularly important due to its aroma, color, partial taste formation, and antimicrobial effects. The aim of this study was to determine some pomological and chemical characteristics of hawthorn fruits collected from Ankara Province and the districts of Melikgazi, Hacılar, and Sarız in Kayseri Province during 2022-2023. The pomological characteristics of the selected hawthorn genotypes included fruit weight, fruit width, fruit length, and seed weight, while the chemical characteristics examined were pH, soluble solids content (SSC), titratable acidity (TA), vitamin C, phenolic compounds, flavonoids, antioxidant capacity (measured by DPPH), and anthocyanin content. The study found that the maximum fruit weight was 2.80 grams, with a fruit width of 18.80 mm and a fruit length of 16.01 mm. The seed weight was 0.99 grams. Regarding chemical characteristics, the pH was 3.91, titratable acidity was 2.5%, soluble solids content (SSC) was 14.3%, and the vitamin C content was 71.03 mg/100 g. The total phenolic content was 773.32 µg GAE/100 g, while the total flavonoid content was 23.87 mg CE/100 g. The antioxidant activity was determined to be 74.40%, and the anthocyanin content was found to be 1.11 μg cy-3-glu/g TA.
