Abstract:The optimization of polysaccharide extraction process in compound cordyceps granules was carried out by using Boxhken design and star point response surface method.The effects of material-liquid ratio，extraction time and soaking time and extraction times on the yield of polysaccharide were investigated by single factor experiment.Through the Box-Behnken design star point response surface test，the polysaccharide extraction process of Cordyceps militaris，Canoderma lucidum，licorice，jujube，wheat and platycodon was optimized.The optimized extraction process was：material-liquid ratio 1 ∶16.75 （g/mL），extraction time 2 h，soaking time 2.4 h，extraction times 3 times.The extraction process was optimized by the Box-Behnken method，and the test results were reasonable and effective，and the optimization effect was good.
