Abstract
<jats:p xml:lang="en">Aim: Helichrysum arenarium (L.) Moench is perennial herbaceous plant belongs to the Asteraceae family and is widely distributed in Europe and Asia. It is used in medicine due to its phytochemicals. Material and Metod: In the current study, extracts were obtained using ethanol, water and chloroform solvents, and the antioxidant potentials of the obtained extracts were determined by various in vitro tests. Results: In the DPPH radical scavenging activity test the ethanol extract showed higher inhibition than the other extract samples. The Ec50 values for ethanol, chloroform, and water was determined as 16.60 µg/mL, 85.67 µg/mL and 175.86 µg/mL respectively. This is thought to be related to the ratio of phenolic compounds released during extraction. Also the obtained extract samples has moderate Nitric oxide, superoxide and hydrogen peroxide scavenging activity. Conclusion: These findings suggest that H. arenarium may serve as a potential natural source of antioxidants.</jats:p>
