In this study, Zea mays L., which were discarded after harvesting in Korea, were collected and used for experiment. The Zea mays L. were dried in the shade and ground before being extracted using two solvents. Subsequently, DPPH, ABTS, the total flavonoid content and the total polyphenol content were measured to analyze antioxidant activity. The diameter of clear zone was measured by using the paper disc diffusion method. The results showed that the ethanol extract had a slightly higher antioxidant and antibacterial activity. The total polyphenol content was measured using gallic acid as standard, and CE(ethanol extract) was found to contain 31.2±5.2 ㎎ GAE/g of polyphenols, indicating a considerably high activity. When DPPH radical scavenging ability was measured, CE was found to have 4.6±0.9%, 6.4±0.5%, 22.9±0.6% and 83.2±0.2% at different concentrations of 1 ㎍/mL, 10 ㎍/mL, 100 ㎍/mL, and 1,000 ㎍/mL, respectively, with a dependent tendency at the concentration of 1,000 ㎍/mL and a considerably high activity at the concentration of 1,000 ㎍/mL. This study is expected to be used as preliminary data to develop new natural antioxidant, antibacteria raw materials, as only little research has been undertaken on Zea mays L., which are mostly discarded after harvesting, while many studies have been so far conducted on corn and corn silks.
