Abstract

|
|
|
We examined the macrophage activity of Codonopsis lanceolata and its effect on the growth of lactic starter culture when it was added to fermented milk. Nitric oxide(NO) and interleukin-1 were increased significantly(p<0.05) by addition of Codonopsis lanceolata water extract at . Tumer necrosis factor- was increased significantly (p<0.05) by addition of Codonopsis lanceolata water extract or 70% ethanol extract at . Water extract of Codonopsis lanceolata showed higher macrophage activity than 70% ethanol extract. Growth of lactic starter culture was inhibited by the increased addition of Codonopsis lanceolata water extract, resulting in less decrease in pH. A stirred type or drink type fermentation process seemed mote suitable than a set type in proper production of Codonopsis lanceolata extract added fermented milk.
