    [Abstract] Objective To study the optimum extraction of polysaccharide from Tussilagofarfara waste. Methods Response surface methodology was used to optimize the extraction process for Tussilagofarfara waste. The effect of time， pH and temperature were addressed using response surface methodology. Results The optimal extraction conditions were determined as follows： pH of 9.5， temperature of 61℃， time of 85 min， and material-to-liquid ratio of 20 (mL/g). Under these conditions， the extraction yield of polysaccharide was 4.211% ......
