[Objective]The study aimed to confirm the effects of peeling and drying temperature on polysaccharides content of Radix platycodonis,and providing reference for establishing the best habitat processing of it.[Method]Extracted with water,refined with ethanol,the contents of polysaccharides in Radix platycodonis were determined by phenol-H2SO4 colorimetry method.[Result]The polysaccharides content between the unpeeled sample and the peel varied a little,both of which were lower than that in the peeled sample.The drying speed of the peeled samples was promoted,and the content of polysaccharides was the highest dried at 50 ℃.[Conclusion]As the content of polysaccharides in peeled sample increased 6.1%,and peeled sample was easier to dry,peeling was screened as the final processing method.
