@@@@The conditions for extracting polysaccharides from Mallotus furetianus tea with the assistance of ultrasound were optimized by single factor and orthogonal array design methods in this study. The optimal extraction process conditions were determined as follows: ultrasound power 200 W, ultrasound extraction duration 20 min,temperature 70℃, and liquid/material ratio 20∶1(mL/g) and hot water extraction duration 30 min, temperature 70℃. Under these conditions,the extraction yield of TPS from Mallotus furetianus tea was 9.976%. The importance of the five process conditions affecting polysaccharide extraction was ultrasound power ,ultrasound temperature,ultrasound duration,extraction duration,and liquid/material ratio as decreasing order.
