Abstract: The extraction technique of Lycium Barbarum Polysaccharide by ultrasound Optimum extraction for LBP was at 50℃ and 60 volume of adding water keep for 2.5h, then extracted by ultrasound for 5min,the extraction rate was 50.36 % ,which were obtained by orthogonal test. Furthermore the contents of Lycium Barbarum Polysaccharides(LBP) was analysed by spectrphotometric methods.

Key words: ultrasound extraction, lycium barbarum, lycium barbarum polysaccharide(LBP)
