Abstract :The aims of this study were insert ignore into journalissuearticles values(1); to assess the extract yield, antioxidant activity, and antimicrobial activity of Cistus creticus extracts obtained from different locations in Türkiye insert ignore into journalissuearticles values(2); to evaluate the effect of water and methanol solvents on chemical composition, total polyphenol and flavonoid content, IC50, and FRAP values of C. creticus. The extracts had a weak inhibitory effect against tested microorganisms. However, the results of antioxidant assays were very promising. The IC50 values of methanol and water extracts were 13.94 µg/mL and 34.41 µg/mL, respectively. Similarly, the FRAP value of methanolic extract insert ignore into journalissuearticles values(1.27 M/g); was higher than the water extract insert ignore into journalissuearticles values(0.72 M/g);. The results of HPLC analysis demonstrated that rutin was found only in the methanol extract insert ignore into journalissuearticles values(13.252%);. In addition, the methanol extract had a higher content of quercetin insert ignore into journalissuearticles values(7.909%);, benzoic acid insert ignore into journalissuearticles values(4.226%);, and chlorogenic acid insert ignore into journalissuearticles values(2.168%);, whereas the water extract possessed a higher amount of gallic acid insert ignore into journalissuearticles values(13.705%);.
