TOTAL POLYPHENOLS, FLAVONOIDS CONTENTS AND ANTIOXIDANT ACTIVITY OF ROSA SP. GENOTIPES FROM DIFFERENT ALTITUDE OF ROMANIAN REGIONS
Eight wild rose hip genotypes from different altitudes varying from 3m to 902m were analyzed in order to evaluate the total polyphenols, flavonoids content and the antioxidant activity. The Rosa spp.rosehips collected from the Northeastern and the Southeasternof Romanianwere, as follows: Rosa canina, R. caesia, R. corymbifera, R. micrantha, R. nitidula, R. rubiginosa, R. subcanina, and R. vosagiaca. In some genotypes, the level of flavonoids and polyphenol content increased with the increasing altitude while in other it was observed a decrease. Polyphenol content reached a maximum of 144.36 mg GAE/g DW in R. rubiginosa whereas the lowest content of 61.72 mg GAE/g DW was recorded in R. caesia. The highest polyphenol content was reached at altitude of 860 m. The amount of flavonoids content ranged between 7.32 mg CE/g DW and 19.45 CE/g DW in R. caesia and in R. nitidula, respectively. The radical scavenging capacities of Rosa genotypes extracts were not positively correlated with altitude, except the R. corymbifera extractswhere the antioxidant activity increased with the increase of altitude.
