Plackett-Burman design was used to screen the extraction conditions. The relevant factors were ultrasonic temperature，
ultrasonic power，ultrasonic time，liquid-solid ratio and extraction times. The steepest climbing experiment was carried
out to determine the center point of the three most significant factors. Through Box-Benhnken Design experiment，the
Results
optimal extraction process parameters of mango polysaccharide were obtained. 　 The optimum extraction pa-
rameters were as follows：the ratio of liquid to material was 32∶ 1 （mL∶ g)，the ultrasonic temperature was 33 ℃ ，and
Conclusion
the extraction times were 3. 58% . 　 Tesponse surface methodology is reliable to optimize the technology
of mango polysaccharide.
