Abstract: The technology of ultrasonic dilapidating walls was used to extract pine pollen polysaccharides and the optimum parameters were obtained:ultrasonic power 400 W,solid to liquid ratio 1:12,ultrasonic time 10min,extracting temperature 80 ℃.Protein was removed 3 times to pure polysaccharides by the Sevag.The extraction yield of polysaccharides is 18.54 mg/g under the condition of optimum parameters and increased 2.02 times compared with water extraction.

Key words: pine pollen, polysaccharides, ultrasonic, dilapidating walls
