ABSTRACT
A number of 6-hydroxy-2-benzylidene-3-coumaranones were synthesized from condensation of 6-hydroxy-3-coumaranone with appropriate aldehydes and were evaluated for their antioxidant activities. The antioxidant activity was assessed using two methods, including, 1,1-biphenyl-2-picrylhydrazyl [DPPH] radical scavenging, and reducing power assays. Some of the benzylidene coumaranones showed antioxidant activity more than Trolox as reference antioxidant
