Embodiment 1

[0029] Select the rhizomes of Morinda officinalis, wash them first, remove impurities, dry them at 60°C, and then crush them to 60 mesh with a pulverizer to obtain Morinda officinalis powder. Weigh 100g of Morinda officinalis powder without adding it to 400g of chloroform / methanol mixed solvent (chloroform: the volume ratio of methanol is 2: 1), be warming up to under the condition of 60 ℃, reflux 2 hours, carry out degreasing, decolorization treatment, after reflux finishes, filter, remove filtrate, collect filter cake, will The collected filter cake was added into an aqueous ethanol solution with a volume fraction of 80%, and refluxed for 2 hours under the condition of raising the temperature to 80°C. After the reflux was completed, filter, remove the filtrate, and then add the obtained solid to 100mL of distilled water, and heat up to Stir and extract at 60°C for 1 hour, filter, collect the filtrate, and extract the remaining residue; raise the temperature of the collected ...

[0032] Select the rhizomes of Morinda officinalis, wash them first, remove impurities, dry them at 60°C, and then crush them to 40 mesh with a pulverizer to obtain Morinda officinalis powder. Weigh 100g of Morinda officinalis powder without adding it to 1500g of chloroform / methanol mixed solvent (chloroform: the volume ratio of methanol is 4: 1), be warming up to under the condition of 60 ℃, reflux 2 hours, carry out degreasing, decolorization treatment, after reflux finishes, filter, remove filtrate, collect filter cake, will The collected filter cake was added into an aqueous ethanol solution with a volume fraction of 85%, and refluxed for 2 hours under the condition of raising the temperature to 80°C. After the reflux was completed, filter, remove the filtrate, and then add the obtained solid to 100mL of distilled water, and heat up to 50°C, stir and extract for 2 hours, filter, collect the filtrate, add the remaining residue to water, heat up to 50°C, stir, extract for 2 h...

Embodiment 3

[0035] Select the rhizomes of Morinda officinalis, wash them first, remove impurities, dry them at 60°C, and then crush them to 80 mesh with a pulverizer to obtain Morinda officinalis powder. Weigh 100g of Morinda officinalis powder without adding it to 400g of chloroform / methanol mixed solvent (chloroform: the volume ratio of methanol is 3: 1), be warming up to under the condition of 60 ℃, reflux 2 hours, carry out degreasing, decolorization treatment, after reflux finishes, filter, remove filtrate, collect filter cake, will The collected filter cake was added into ethanol aqueous solution with a volume fraction of 75%, and refluxed for 2 hours under the condition of raising the temperature to 80° C. After the reflux was completed, filtered, and the filtrate was removed, and the obtained solid was added to 100 mL of distilled water, and the temperature was raised to 70°C, stir and extract for 0.5 hours, filter, collect the filtrate, add the remaining residue to water, heat up...

Abstract

The invention provides an extraction method of morindea officinalis polysaccharide, belonging to the technical field of traditional Chinese medicines and solving the problems that in the existing morindea officinalis polysaccharide extraction method, the extraction method has complicated process steps and a poor protein removal effect, and the yield and purity of the obtained morindea officinalispolysaccharide are low. The extraction method of morindea officinalis polysaccharide in the invention comprises the following steps of: drying morindea officinalis rhizome and then smashing to 40-80 meshes; adding a chloroform/methanol mixed solvent in morindea officinalis powder for carrying out reflux extraction; carrying out alcohol extraction on a filter cake obtained by filtration and then adding water for lixiviation; subsequently, filtering and concentrating a filtrate, carrying out alcohol precipitation on a concentrated liquid and then filtering so as to obtain the crude morindea officinalis polysaccharide; adding the crude morindea officinalis polysaccharide into a n-butanol/trichloroacetic acid mixed solvent for processing, and entering a chromatographic column for elution; andcarrying out concentration, alcohol precipitation, filtration and drying on an effluent liquid so as to obtain the morindea officinalis polysaccharide. The extraction method of the morindea officinalis polysaccharide in the invention has a simple process and a good protein removal effect, and the extracted morindea officinalis polysaccharide has less impurities and high yield and purity.

Description
