Mudan cortex of paeonia
suffrulicosa was extracted with water ( 20-30℃), hot water (40℃) and boiling water (100℃),
treated with ethanol to remove and obtain the crude polysaccharide. Then crude PSM were
purified by DEAE Cellulose DE-52 column to get pure PSM. The laters were given to mice
intraperitoneally. Results showed that PSM extracted with water (20-30℃) and hot water (40℃)
can markedly lower the serum glucose, but PSM extracted with boiling water...
