Evaluation of Antioxidant Activities and Phenolic Compounds of Scorzonera latifolia (Fisch. & Mey.) DC. Collected from Different Geographic Origins in Turkey
Journal Title: Turkish Journal of Pharmaceutical Sciences - Year 2017, Vol 14, Issue 2
Abstract
Objectives: The chemical composition of plants is considered to be affected by many parameters. Therefore, the region where the samples are collected is likely to have an influence on the composition of phenolic compounds, so that their biological activities. In the present study, evaluation of antioxidant activity potentials of Scorzonera latifolia (Fisch. & Mey.) DC. aerial parts and roots, which were collected from different regions of Turkey, was aimed. Materials and Methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method and measurement of malondialdehyde (MDA) levels were used for determining antioxidant capacities of the tested extracts. In order to observe variations in the chemical composition of the investigated samples qualitatively as well as quantitatively, high performance liquid chromatography analyses were performed. Results: Quantitative analysis showed that the amounts of chlorogenic acid and hyperoside in plants vary according to the regions where the samples were collected. As a result aerial parts of the S. latifolia collected from the Kars region have found to contain higher amount of chlorogenic acid (1246.78±3.20 µg/g) as well as hyperoside (652.32±2.48 µg/g) than other samples. The highest DPPH radical scavenging activity was determined with the IC50 value of 1.036 mg/mL for S. latifolia aerial parts of Kayseri sample. MDA level was detected as the lowest with treatment of S. latifolia Bayburt root sample (4.41 nmol/mL). Conclusion: According to the antioxidant activity results, no significant difference was observed in the antioxidant potential between the samples collected from different locations except for S. latifolia collected from the Kars region.
