Background: Primula vulgaris has been used in traditional treatment, and its biological functions are attributed to its polyphenolics content. Objectives: The aim of this study was to determine the phenolics composition and the antioxidant activity of water extract of P. vulgaris (WEP) and to determine its probable preventive effects against H2O2-induced DNA damage in human fibroblast cells. Methods: The total polyphenolic content (TPC), ferric reducing antioxidant power (FRAP), and radical scavenging activity of WEP were determined using spectrophotometric methods. Phenolic compounds and antigenotoxic effects of WEP were evaluated using HPLC and comet assay, respectively. Results: The TPC and FRAP values of WEP were 15.023 ± 0.84 mg gallic acid and 82.63 ± 0.31 μM trolox per g sample, respectively. ρ-coumaric acid and rutin were detected as major phenolics. Moreover, WEP reducedH2O2-induced DNA damage in a concentration dependent manner in fibroblast cells compared to the positive controls (only 20 μMH2O2 treatment). Conclusions: Primula vulgaris can be used in food, cosmetics, and drug industries because of its antioxidant and antigenotoxic activities.

Aim of Study: Propolis is a resinous bee product, rich of polyphenolic compounds and flavonoids. It is known that in different geographic zones its chemical composition varies due to the different plant sources. Many biological properties including antimicrobial, antioxidative, anti-inflammatory, antitumoral, antigenotoxic, antimutagenic, cytostatic activities have been ascribed to propolis. These biological effects are predominantly attributed to its content of polyphenols. In this study, we aimed to evaluate the radioprotective effect of ethanolic extract of Turkish propolis. (EETP) against γ-ray-induced DNA damage on fibroblast cells using comet assay for the first time. Materials and Methods: Fibroblast cells were pretreated 15 and 30 min with concentrations of 100, 200 and 300 μg/mL EETP then they were exposed to 3 Gy γ-rays. Amifostine (synthetic aminothiol compound) was used as a positive control. Results: The results showed a significant decrease in γ-ray-induced DNA damage on cells treated with EETP and amifostine when compared to only irradiated cells. (P < 001). Conclusion: It was concluded that EETP prevent γ-ray-induced DNA damage in fibroblast cells and might have radioprotective activity.
