| Popis: | This work presents shows the study of antioxidant activity and quantification of phenolic content determined for the methanol extract obtained from Commiphora myrrha . The high content of phenolic compounds were evaluated against the potential to sequester free radical through the model 2,2-diphenyl-1-picrizil hydrazyl (DPPH) and compared with a standard rutin. The results show that the inhibitory capacity of the extract (IC 50 ) was 0.21 mg.L -1 . The extract pursued an antioxidant activity of 91.3% compared to the scavenging ability of rutin standard. The content of phenolic extract was assessed by using the Folin-Ciocalteu determined where the IC 50 was 3,02 mg.L -1 . The concentration of total phenols was determined 1.176 ± 0.263 mg gallic acid equivalent . g -1 of extract (n=5). The results show that extracts of C. myrrha have high antioxidant potential and additional studies are needed for isolation, characterization and use of their property in pharmaceutical, nutritinal and cosmetology. |
