Chemical Characterization and Antioxidant Activity of Rosa canina L. From Çekerek Region of Yozgat, Turkey

Abstract

Rosehip, renowned for its bioactive richness, including phenolic acids, flavonoids, carotenoids, and ascorbic acid, exhibits significant antioxidant and health-promoting potential. This study investigated the physicochemical, mineral, and phytochemical characteristics of rosehips sourced from the Çekerek region of Yozgat, Turkey, to evaluate their suitability as a functional food. The rosehips exhibited high dry matter content and low water activity, suggesting excellent stability for storage and processing. Furthermore, the rosehips contained substantial mineral content, including potassium, calcium, magnesium, iron, and zinc, which enhances their nutritional value. Phytochemical analysis revealed a significant phenolic content, potent antioxidant activity, and exceptional vitamin C levels, positioning Çekerek rosehips as a superior natural antioxidant source. These findings underscore the influence of Çekerek's unique environmental conditions on rosehip composition and highlight their potential applications in the functional food, nutraceutical, and pharmaceutical sectors, addressing the increasing demand for natural antioxidants. This research contributes to the understanding of regional variations in Rosa canina and provides a basis for further investigation into the bioavailability, clinical applications, and development of value-added products from Çekerek rosehips.
