Abstract: In this paper, Ultra-high pressure technology(UHP)was used to extract polysaccharide from Radix Puerariae with the extraction rate of polysaccharide as the evaluation index. UHP pressure level, UHP time, solid-liquid ratio and soaking time were analyzed. Through single factor and orthogonal test, the optimal extraction conditions were obtained: liquid ratio 1∶50(g/mL), UHP pressure 300 MPa, UHP time 3 min, soaking time 90 min. Under these conditions, ultra high pressure extraction rate of extraction of polysaccharide was 23.81 mg/g.

Key words: Radix Puerariae, polysaccharides, Ultra-high pressure technology(UHP), process optimization
