چکیده انگلیسی
Aim of the present study was to characterize and to compare phenolic composition and antioxidant properties of methanol (MeOH) and ethyl acetate (EtOAc) extracts from leaves of Rosa canina, Rosa sempervirens and Rosa moschata collected from different Tunisian regions. Fifteen phenolic compounds were identified by means of HPLC-DAD and HPLC-DAD-ESI-MS analyses. It was shown that phenolic composition of Rosa canina extracts includes two kaempferol derivatives (Kaempferol 3-O-glucoside and kaempferol 7-O-glucoside) which are not present in profiles of the two Synstylae species. Rosa moschata and Rosa sempervirens extracts are rich in quercetin derivatives. As regarding the total phenolic content (evaluated by the Folin-Ciocalteu assay), R. sempervirens and R. moschata showed the highest values with their EtOAc and MeOH extracts, respectively. The highest mean values for DPPH, TEAC and FRAP tests were recorded for the EtOAc extracts of R. sempervirens and for the MeOH extracts of R. canina. In the ORAC assay, R. moschata and R. sempervirens showed the highest effectiveness for EtOAc and MeOH extracts, respectively. Taken together, these data suggest that leaf extracts of different Tunisian Rosa species should be used as a potential source of antioxidant phenolics, and R. sempervirens and R. moschata are a good alternative to R. canina especially in those regions where these species can be easily found.
