Objective : To establish the optimal ultrasonic extraction technology of polysaccharides from Polygoni Multiflori Radix Praeparata. Method :Extraction time
extraction times
the ratio of sample to solution
and extraction temperature were set as index for orthogonal test
and Compared with hot water extraction method. Result :The optimal ultrasonic extraction Process of polysaccharides from Polygoni Multiflori Radix Praeparata was extracted 2 times for 50 min each time at 70 ℃ with the ratio of dry material to water was 1 ∶25
the yield of polysaccharides is 20.04%. Compared with water extraction
the extraction time reduced obviously. Conclusion :The optimum ultrasonic extraction process for polysaccharides is rapid
