Studied on Extraction Process of Polysaccharide in Herpetospermum Pedunculosum(ser) C.B.Clarke by Ultrasonic Extraction

To get optimal conditions for extraction of polysaccharide in Herpetospermum pedunculosum.Employing ultrasonic technique to extract polysaccharide,using orthogonal experimental design to treat the data,applying ultraviolet-visible spectrometry to determine content of polysaccharide.The optimal conditions for extraction of polysaccharide are as follows.To grind the material and scree with a 8# sieve,the ratio of taw material to water is,the time for extraction is 1 hour.The ultrasonic extraction of polysaccharide in Herpetospermum pedunculosum is stable and feasible.
