Abstract
Introduction: The objective of this study is to investigate the chemical characteristics of Paeonia - Itecik tulip and to evaluate the antioxidant and antimicrobial activities of an extract obtained from its petals and leaves.
Materials and Methods: Itecik tulip is native to Uşak region and its extracts were prepared to determine the antioxidant activity by using total flavonoid content analysis and phenolic content assay methods.
Results: It was detected that radical scavenging activity was higher in the petals than in the leaves, total phenolic content was 23.75 mg GAE/gr in the extract taken from the petals and flavonoid content was higher in the leaves than in the petals. Furthermore, in terms of antimicrobial activity, it was found that it was approximately 3 times more effective against K. Pneumoniae compared to Erythromycin and 2.5 times more effective compared to Penicillin and Vancomycin.
Conclusions: It can be concluded that our study subject Itecik tulip leaves may be effective in terms of antioxidant activity and radical scavenging activity It may be useful to compare Paeonia petals with more antibiotics to assess its efficacy. In our research, we would like to emphasize that we will have played a role especially in the recognition of itecik tulip.
