[Objective]To optimize the extract technology of polysaccharides from Dendrobium huoshanense.[Method]Effects of solid-liquid ratio, extraction time and ultrasonic power on the extraction rate of polysaccharides from D.huoshanense were studied by response surface method.[Result]The optimal extraction condition was as follows:1∶10(g/ml)solid-liquid ratio,30 min extraction time,and 250 W ultrasonic power.Under this condition,the extraction rate of polysaccharides from D.huoshanense reached 28.02%.[Conclusion]This method optimized the ultrasonic assisted extraction of polysaccharides from D.huoshanense,which provided references for the development and utilization of polysaccharides in D.huoshanense.
