Embodiment 1

[0039] Take 1 kg of Cyclocarya paliurus leaves, crush them until the leaf fragments are less than 2cm, add 10 kg of water, heat to 70°C, keep the temperature, soak for 5 hours, and extract 3 times; filter with a 250-mesh filter to obtain Cyclocarya paliurus extract , the waste leaf residue can be used to make fertilizers, etc.; the PH value of the leachate is 6, the leachate is cooled to 25-30°C, and passed through the first-stage pressure pump at a working pressure of 0.02-0.05Mpa through the first ultrafiltration membrane (molecular weight cut-off is 10000) Separation module, passing through the first heavy membrane, intercepting and separating the concentrated paliurus paliurus fiber, protein, pectin, polysaccharide, etc., and sending it out from the first outlet, concentrating paliurus paliurus polysaccharide solution, and obtaining polycarya paliurus polysaccharide concentrate , then add ethanol to the alcohol content of 70-85%, let it stand, filter the precipitate with a ...

Embodiment 2

[0042] Take 1 kg of Cyclocarya paliurus leaves, crush them, add 75% EtOH, heat and reflux for 5 hours, filter with a 250-mesh filter to obtain Cyclocarya EtOH extract, concentrate the extract to recover EtOH, dilute the concentrate with water, and then perform macroporation Resin adsorption, elution, alcohol elution, concentration, and drying to obtain organic small molecule products; after removing ethanol from leaf residue, add 10 kg of water, heat to 70°C, keep the temperature, soak for 5 hours, and extract 3 times. Filtrate with a 250-mesh filter to obtain Cyclocarya paliurus polysaccharide extract, and the waste leaf residue can be used for fertilizer production. The PH value of the leachate is 6, the leachate is cooled to 25-30°C, passes through the first-stage pressure pump, and passes through the first ultrafiltration membrane (molecular weight cut-off is 10,000) separation module at a working pressure of 0.02-0.05Mpa, and passes through the first-stage membrane , inte...

Abstract

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.

Description

Technical field: [0001] The invention relates to a method for extracting plant active ingredients, in particular to a method for extracting polysaccharides and active ingredients from Cyclocarya paliurus. Background technique: [0002] Cyclocarya paliurus (Batal.) lljinsk is a species of dicotyledonous plants [Dicotyledneae] Juglangdaceae [Juglangdaceae], a rare and unique tall tree plant in my country. Cyclocarya paliurus is rich in polysaccharide substances and active ingredients with hypoglycemic activity. It also contains trace elements chromium, nickel, lithium, selenium and vanadium with insulin-like effects, which can participate in the glucose metabolism of the human body and can also improve the blood sugar of diabetic mice. Glucose tolerance. [0003] At present, the extraction method of the effective components of Cyclocarya paliurus has attracted widespread attention. Chinese patent application No. 87101852 discloses a "method for extracting sweetener from Cyclo...
