This study was conducted to investigate changes in phenolic and flavonoid content and antioxidant activity according to storage temperature and storage period from root extract of Codonopsis lanceolata (CL). Total polyphenol and flavonoid content decreased with increasing temperature, and the content was relatively high at temperatures of 15°C or less. Under different storage conditions, the total polyphenol and flavonoid content tended to decrease as the storage period became longer. Measurement of the DPPH radical scavenging activity confirmed that components for enhancing antioxidants were contained in the roots of CL, and it was assumed that there was not a large change in the scavenging activity when stored for less than 60 days or at temperatures below 25°C. Shorter storage period and lower storage temperature was associated with relatively high ABTS radical scavenging activity. The nitrite scavenging effect was highest at pH 1.2 in all samples tested; however, there was no distinct detection of nitrite scavenging effects at pH 6.0. In addition, phenolic compounds appear to be responsible for the antioxidant activity of CL extracts. Therefore, the results of the current study suggest that the CL root may assist in potential biological activities and can be used as a source of human health products.
