Determination of Phytochemical Profile, Antiquorum Sensing and Antioxidant Activities of Tragopogon oligolepis

Objective: In this study it was aimed to examine antiquorum sensing, antioxidant activities by using root and aerial parts extracts of Tragopogon oligolepis. Also phenolic content detected HPLC analysis.Material-Method: Antioxidant activity DPPH, FRAP methods HPLC. Antiquorum sensing investigated pyocyanin swarming motility assay on Pseudomonas aeruginosa PAO1. Results: Phytochemical profile findings showed that 12 components were in the 10 parts. The main found chlorogenic acid o-coumaric acid. According obtained levels T. oligolepis had best property our results. amount DPPH (0.60 ± 0.01 mg/ml) (6.55±0.18 mg GAE/g sample) determined be high analysis, reducing power roots (12.62±0.36 μmol FeSO4/g sample). these results, although do not reach very amounts terms is thought a plant can evaluated removing oxidant effects. results both extract strong inhibitory effect 62%, %65 rate respectively.Conclusions: oligolepis, an endemic species, as inhibitor candidate with its phytochemical contents.
