This study investigated the anti-oxidation activities of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans, and also the quality properties of fresh Codonopsis lanceolata Yanggaeng to which raw Codonopsis lanceolata Traut (Benth et Hook) was added. The DPPH free radical scavenging activities of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 31.42% and 37.98%, respectively. Thus, that of red beans was rather the total polyphenol contents of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 5.74 mg/g and 4.14 mg/g respectively, and the total flavonoid contents of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 5.07 mg/g and 1.29 mg/g respectively. As higher amounts of Codonopsis lanceolata Traut (Benth et Hook) were added to Yanggaeng, the water content in the Yanggaeng continued to increase. Preferences were in the following order: 21%>12%>28%>7%>0%, and it was found that the optimal level for addition of fresh Codonopsis lanceolata Traut (Benth et Hook) was between 12% and 21%. It was also shown that adjusting the amount of ingredients or agar would improve the product quality.

The volatile oil of the root of Codonopsis lanceolata Traut. (Benth. et Hook.) was isolated by steam distillation and extraction method and fractionated by silica gel column chromatography. The total volatile oil and each fractions were analyzed by GG, GC-MS and retention indices matching. A total of 50 components were identified in the volatile oil including 16 terpene and terpene alcohols, 13 hydrocarbons, 5 alcohols, 6 aldehyde and ketones, 6 acids, 2 esters and 2 miscellaneous components. The major components were n-hexanal (7.3% of total volatile oil), trans-2-hexenal (24.9%), n-hexanol (19.8%), cis-3-hexen-1-ol (5.6%) and trans-2-hexen-1-ol (29.4%).
