A comparison was made on the extraction of phenolic compounds from dates pulp(Diospyros lotus L.) with different concentrations of ethanol.The result showed that ethanol with a concentration of 80%was a suitable solvent to extract phenolic compounds.Antioxidant activities of the extract with 80%ethanol concentration were measured by DPPH,hydroxyl radical scavenging activities,reducing power and chelating activity assays.The results showed that DPPH and OH radical scavenging activities and reducing power of the extracts was concentration-dependent. Chelating activity of the extract in its Na_2EDTA equivalent was 5.64mg.
