Abstract:: The ultrasonic extraction of polysaccharides from Phyllostachys pubescens leaves was studied.The factors of extraction temperature，time，solid liquid ratio，extraction times were researched.The extraction process of polysaccharides was optimized with single factor test and orthogonal experiments，and there was a comparison between the ultrasonic method and the refluxing method.The results showed that optimum extraction conditions were determined as follows：extraction temperature 70℃，extraction time 20 minutes，stock ratio 1∶10 (material∶volume)，extraction 3 times.And the ultrasonic extraction method was superior to refluxing extraction.
