Abstract

Rosehip, Rosa canina L. fruit, is valued for its flavor, taste, color and aroma, in accordance with its recognition as one of richest sources of pro-health compounds. Screening, preservation and propagation of the most valuable local populations of rosehip are performed for food, pharmacological, and cosmetic applications. Eleven native R. canina genotypes from the Interior Aegean region, Turkey, were collected and analyzed regarding organic acids, phenolic compounds, sugars, and DPPH scavenging activity within this study. Regarding biochemical profile of fruits, protocatechuic acid and quercitrin were the most dominant compounds among 12 identified phenolics. The dominant organic acids were malic and citric and fructose and glucose were the dominant sugars. There was no correlation between DPPH scavenging activity and the analyzed chemicals in fruits. Although levels of certain compounds varied significantly between consecutive years, the ranking of genotypes according to the levels of particular chemicals was maintained. Generally, the most promising chemotype regarding biological value was 64US03. The chemical composition and the presence of bioactive compounds make the native to Interior Aegean R. canina genotypes a valuable source of bioactive agents preventing oxidative-stress related diseases.
