Abstract :Natural products have gained the great interest due to their broad spectrum of biological activities. Galanthus krasnovii was dried at shade then extracted with hexane, dichloromethane, and ethyl acetate successively. After removing of solvent by reduced pressure, crude extracts of each solvent were yielded. Antioxidant activity including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical, 2,2\\\'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical cation and reducing power assays were carried out for each extract. Moreover, total phenolic content was determined. Total phenolic content of hexane-, dichloromethane-, and ethyl acetate extracts were found as 60.95 mg GAE/g extract, 71.90 GAE/g extract and 58.90 GAE/g extract respectively. Dichloromethane and ethyl acetate extract revealed the moderate antioxidant activity.
