In this paper,hydrochloric acid was employed as extracting agent to extract polysaccharides from Perilla meal and the yield is examined from such three factors as temperature,time as well as concentration of HCI.Through orghoagonal text,the optimal conditions for extraction were obtained,extracting time 35min,extracting tenperature 60,and HCL concentration 0.25mol/L respectively.The extraction yield of polysaccharids from Perilla meal was 1.42% under the optiomal condition.
