The invention discloses a method for extracting
polysaccharide and effective components from
cyclocarya paliurus, which comprises the steps as follows: immersing
cyclocarya paliurus leaves with hot water, filtering, the filtrate successively passing through two pieces of membrane under the pressure of 0.01 to 0.2MPa, separating the filtrate by the first membrane, concentrating the filtrate, precipitating by
ethanol, obtaining big molecular
polysaccharide by filtering precipitate; the leaky filtrate passing through the first going through the second membrane, concentrating the filtrate, precipitating with
ethanol, obtaining big molecular
polysaccharide and small molecular polysaccharide and
processing the leaky filtrate to get
organic molecules. The other technique of the invention comprises the steps as follows:
reflux extracting
cyclocarya paliurus with
ethanol, concentrating and recycling ethanol, adsorption with
macroporous resin after
dilution,
elution, concentrating and
drying, then getting small organic molecular products. Treating the dregs after filtering as the steps of the first technique, the products of big molecular polysaccharide and small molecular polysaccharide can be obtained. The method for extracting polysaccharide and effective components from cyclocarya paliurus has the advantages of simple technology, ability to acquire a plurality of effective components, no
pollution of
solvent, recyclability, no
wastewater and dregs, simple equipment and low investment.
