Abstract
The climate and soil condition as well as genetic diversity affect the physicochemical properties of fruits. In this study, 7 wild Hawthorn samples were obtained from different locations of the Çorum province and some physical properties (diameter: 14.5-20.2 mm, length:15.6-25.2 mm, fruit weight: 2.1-8.0 g, flesh:seed ratio: 3.3-7.9), CIE colour values (L*: 48.2-74.6, a*: 7.5-44.9 ve b*:30.3-59.5) and physicochemical properties pH (3.6-4.0), acidity (0.9-1.7%) dry matter (20.8-27.9%), soluble solids (12.6-17.7°Bx) were determined. Total phenolics (155.2-490.3 mg GAE/100 g), total flavonoid (78.7-272.6 mg CE/100 g), proanthocyanidin contents (64.2-132.3 mg CE/100 g) and antioxidant capacity (14.6-44.9 µmol TEAC/g) extracted by thermosonication and measured by spectrophotometrically. These fruits are good source of aforementioned properties. The native fruit population might have an economic potential as value added product such as organic production, food additive, or medicinal purposes. Also, results might be useful to preserve genetic diversty.
