The work involved the study of the contents of ascorbic acid, carotenoids, total flavonoids, total tannins, total phenolics, and antioxidant properties of rose hips of two species: Rosa canina L. and Rosa rugosa Thunb. collected from wild bushes growing on the Curonian Spit, Sambia peninsula, and the Vistula Spit (Kaliningrad region, Russia). Species-specific accumulation of ascorbic acid, carotenoids, flavonoids, phenolics, and total antioxidants was shown. The content of the above components was significantly higher in hips of Rosa rugosa than in rose hips of Rosa canina. With the exception of the total content total water-soluble antioxidants and flavonoids, the content of biologically active compounds was higher in fully ripe fruits compared to unripe and half-ripe fruits. The accumulation of studied phytonutrients depended also on growth locations. In this study was shown high nutritional value of rose hips, especially of the species Rosa rugosa Thunb
