Abstract

Seaweeds have antioxidant properties. In this study, antioxidant activity of red algae Champia compressa organic extracts from Chabahar Bay was investigated. Extraction of the samples was done with a concentration of 1:20 (solvent to algae) by soaking the algae powder for 24 hours at ambient temperature. The solvents included methanol, hexane, dichloromethane and, chloroform at concentrations of 0.01, 0.1, 0.5 and 1, mg/mL. Extracts were subjected to the renowned antioxidant activity assay procedures of DPPH free radical scavenging activity, reduction power and, iron chelating. The minimum IC50 value of DPPH free radical scavenging activity of C. compressa algae was in the methanolic extract with a value of 1.05 mg/mL. The maximum value was calculated in dichloromethane extract. Also, chloroform solvent with IC50 of 2.64 had the highest chelation. Methanolic extract with IC50 of 0.68 mg/mL had the highest reducing activity. with the increase in the concentration of the extract, the amount of its antioxidant activity increased. So, inhibition of DPPH free radical, chelating power and, reducing activity at a concentration of 1 mg/mL of most extracts showed a significant difference compared to other concentrations (p<0.05). In conclusion, the methanolic and chloroform extracts of C. compressa red algae exhibited notable antioxidant properties. Further research for a complete investigation of the antioxidant properties of the C. compressa extracts is need.
