Abstract

The effects of free radicals and active oxygen species on biological molecules Caused many problems in recent years. These compounds are known to be responsible for oxidative deterioration of vital molecules such as proteins, lipids and nucleic acids. Antioxidants protect biological systems against these factors and seems to play a preventing role in human health. In the present study, the antioxidant activity of water and alcoholic extracts of carum copticum was studied. The extracts obtained by ultrasonic and traditional methods. 2,2-Diphenyl-1 picrylhydrazyl (DPPH) was added to the extracts and the antioxidant activity was determined by amount of reagent consumption. For tracking the progress of the reaction, high performance liquid chromatography was used. In order to optimize the extraction conditions, effective parameters such as extracting solvent, temperature and time were investigated. Finally, the results were analyzed by Excel software
