Codonopsis pilosula is a kind of traditional Chinese medicine used to treat weak spleens, stomach problems, anemia, and fatigue. Polysaccharide is one of main components of Codonopsis pilosula. In this study, response surface methodology (RSM) was used to optimize the extraction parameters of Codonopsis pilosula polysaccharides (CPP) by fermentation. The exaction temperature (°C), yeast liquid volume (2mg/ml, ml), and time (h) were employed effects. Results indicated that the best extraction conditions were the following: extraction temperatur...
