초록

This study was investigated the contents of total polyphenol, flavonoids and antioxidant and antimicrobial activities of Codonopsis lanceolata extracts according to different steaming times. The contents of total polyphenol and flavonoid proportionally increased from 6.45 mgGAE/g to 18.26 mgGAE/g and 2.01 mgRE/g to 6.12 mgRE/g according to ethanol extracts at EDS7. DPPH radical scavenging activity was found to have been 15.26~65.2% and showed the highest level of antioxidant activity at EDS7 was 65.2%. The activity of ABTS radical scavenging and SOD-like activity were also the same result. DPPH and ABTS radical scavenging activity was related to the number of steaming, and the scavenging activity was increased up to 7 times of steaming. The antimicrobial activity of EDS7 had strong antioxidant activity. Antimicrobial activities were examined against 5 microorganisms related to pathogens and food poisoning. The antimicrobial Activity was different depending on the bacteria, but it was effective at the concentration of 300 mg/mL rather than 150 mg/mL. These results showed that Codonopsis lanceolata extracts with a different number of steaming would be conducted to confirm the possibility of developing antimicrobial and antioxidant. It will be helpful in the study of component analysis of Codonopsis lanceolata extracts processed products.
