In this study, fruits, fruit flesh and seeds of Rosa damascena and Rosa canina were assayed for the composition of fatty acids, ascorbic acid, alpha-tocopherol, beta-carotene, and mineral elements. The concentration of linoleic acid in seed oil of R. damascena (54.18%) was higher than in R. canina (48.84%). Alpha-tocopherol concentrations were found to be 7.10 microg/g and 34.20 microg/g for R. damascena and R. canina fruits, respectively. Ascorbic acid conc. was determined as the highest in the fruit flesh (546 mg/100 g in R. damascena and 2,200 mg/100 g in R. canina), and as the lowest in the seeds of both species. R. damascena fruits were found to be richer in minerals such as Ca, Fe, K, Mn, Na, P, and Zn than R. canina fruits. The results of the present study showed that R. damascena fruits could be used as food and food additive equally as rose hip fruits.
