Study on extraction, purification and blood - sugar lowering of a polysaccharide from danpi (root shin of Paeonia suffruticasa Andr. )

Zhang Buchang et al (Biology Dept,Anhui University,Hefei, 230039 )  
Danpi polysaccharide (DP) was obtained from Danpi(root skin of Paeonia suffruticosa Andr. )with cold water extraction and DEAE-Cellulose column chromatography. Gel chromatography and electrophoresis showed that DP was homogeneous. Carbazole reaction and paper chromatography revealed that DP was a kind of acidic polysaccharide. Pharmacological test verified that DP could significantly lower mice blood sugar.
