Rosehip is one of the widest spread species of gender Rosa in the Republic of Croatia. Its rich nutritional and medicinal value and relative easy cultivation make it a plant species of great potential for cultivation in Croatia. The main aim of this graduate thesis was to determine the differences in the chemical composition and bioactive compounds content between wildgrown rosehip fruits, from conventional and organic cultivation. Following chemical analysis, in purpose of determining nutritional composition, was conducted: dry matter content (%), soluble dry matter content (%), total acidity content (%), pH- value, vitamin C content (mg/100 g fresh weight), total phenols content (mgGAE/100 g), total anthocyanins content (mg/L), β-carotene content (μg/100 g fresh weight), and antioxidant capacity (μmolTE/L). Vitamin C content ranged from 79,26 mg/100 g fresh weight (wildgrown fruit) to 341,92 mg/100 g fresh weight (fruit from conventional farming). Total phenols content ranged from 1109,62 mg GAE/100 g (fruit from conventional farming) to 1310,79 mg GAE/100 g (fruit from organic farming). β-caroten content ranged from 13 663 μg/100 g fresh weight (fruit from organic farming) to 29 500 μg/100 g fresh weight (wildegrown fruit). Following the determined high content of bioactive compounds in analyzed rosehip samples, a high antioxidative capacity was also determined, ranging from 2263,68 μmol TE/L (fruit from conventional farming) to 2276,57 μmol TE/L (fruit from organic farming). Based on the obtained results it can be concluded that the rosehip fruit are valuable source of bioactive compounds and that the fruit quality ( nutritional composition of fruit) significantly depends on the cultvation method.
