Summary: | The objective of this work was to determine some bioactive compounds for four different rosehip species (Rosa L.), growing in the East Anatolia region of Turkey. It was determined that the average fruit weights of the species varied between 9.8 g (R. dumalis) and 34.5 g (R. canina). The total soluble solids showed statistically significant variations among the rosehip species (14-22 [degrees]Brix). The acidity was inversely proportional to total soluble solids and ranged between 1.00% (R. canina) and 2.67% (R. villosa). The highest total phenolic, L-ascorbic acid contents and the highest total antioxidant capacity were found in R. canina. The total phenolic, total anthocyanin, total dry matter, and L-ascorbic acid contents and the total antioxidant capacity of the rosehip species ranged as follows 1081- 6298 mg gallic acid equivalent/100 g, 2.43-3.72 mg/100 g, 40.1-56.7%, 24.93-754.48 mg/100 g, and 10.04-97.95 mmol trolox equivalent/g, respectively. Glucose was the most common sugar in Rosa species (5.99-12.48 g/100 g), the major organic acid in the rosehip species was citric acid (0.48-1.05 g/100 g). A dendogram based on some pomological and biochemical characteristics of the rosehip species were grouped into 2 main clusters. Findings on the biochemical characteristics of the species will provide insights to plant breeders /growers and for further research. Keywords: antioxidant, organic acids, phenolic, rosehip, sugars |
