The invention relates to a preparation method of
allium chinense
polysaccharide. According to the preparation method,
allium chinense is adopted as main
raw material, sieving is carried out after the raw materials are processed into
powder, and an internal boiling method is adopted:
ethanol is added for infiltration, then, hot water is added for extraction, suction
filtration is carried out after completion of the extraction, the filtrate is concentrated, the
ethanol is added so that the final concentration of the
ethanol is 60 percent to 90 percent, still standing is carried out for 12 hours, and precipitates are
polysaccharide.
Anhydrous ethanol,
acetone and
diethyl ether with the quantity being one time or two times of the weight volume of the precipitates are sequentially added into the
allium chinense
polysaccharide precipitates for washing, precipitates obtained after supernate removal are frozen and dried, and the
allium chinense polysaccharide is obtained. The method has the advantages that the process is simple, the cost is low, the
raw material sources are wide, in addition, the internal boiling method is used for extracting the
allium chinense polysaccharide, the extraction velocity can be accelerated, and the yield of the
allium chinense polysaccharide can also be improved. Researches show that allium chinense contains rich polysaccharide, and specific
biological activity effects of the allium chinense are realized in the aspects of
tumor resistance, anti-
inflammation, antivirus, hyperglycemic,
aging resistance, anticoagulation and the like.
