This study was conducted to investigate the antioxidant activity of Jeolpyeon containing lotus seed powder. Original Jeolpyeon and Jeolpyeon with BHT (butyl hydroxy toluene) werecompared. Antioxidant activities were measured based ontotal polyphenolic contents, total flavonoid contents, DPPH radicalscavenging activity, reducing power, and SOD-like activity. Total polyphenolic and total flavonoid contents of Jeolpyeon containing lotus seed powder were estimated at 37.81±0.45 mg GAE/g and 26.35±0.13 mg QE/g respectively. DPPH radical scavenging activity increased upon addition of lotus seed powder. Further, reducing power was higher in Jeolpyeon containing lotus seed powder than original Jeolpyeon or Jeolpyeon with BHT. The antioxidative effect of Jeolpyeon significantly increased uponaddition of lotus seed powder.
