Abstract: The aim of this study was to optimize the extraction process of crude polysaccharide from Fritillary taipaiensis P.Y.Li (FTP).On the basis of single factor experiments with the method of ultrasonic-assisted extraction,extraction parameters was investigated using response surface methodology.A mathematical model including solid/liquid ratio,ultrasonic time and extraction temperature was created.By typicality analysis,the optimized extraction conditions were as follows:ultrasonic time of 16 min,extraction temperature of 75 ℃ and solid/liquid ratio of 1:15 (g/mL).Under the optimized conditions,the extraction yield of crude polysaccharide was determined to be 0.461%.The results showed that the optimization process using response surface methodology was feasible.It can be used in practical forecasting.

Key words: Fritillary Taipaiensis P.Y.Li, crude polysaccharide, ultrasonic-assisted extraction, response surface methodology
