Problems solved by technology

[0004] At present, polysaccharides from Polygonatum polysaccharides are mostly extracted by direct water extraction followed by alcohol precipitation or by other auxiliary means such as ultrasound, but the extraction rate is still low and the liquid material is relatively high, which consumes a lot of energy.
Patent No. 200910012185.7 records a method for extracting Polygonatum polysaccharides. The crude drug powder of Polygonatum officinalis is subjected to ultrasonic extraction with a solid-liquid ratio of 1:15-40, and then alcohol precipitation is carried out to obtain polysaccharides from Polygonatum polysaccharides. The yield is about 9%, and the energy consumption Large and low yield

Abstract

The invention relates to an extraction method of polygonatum odoratum polysaccharide and a polygonatum odoratum polysaccharide extractive. The extraction method comprises the following steps of (1) enzymolysis: taking rhizoma polygonati odorati, adding water and enzyme, and performing uniform mixing and enzymatic reaction, wherein the addition quantity of the water is 6-10 times of the mass of therhizoma polygonati odorati, and the addition quantity of the enzyme is 0.2-0.4 percent of the mass of the rhizoma polygonati odorati; (2) water extraction: after enzymolysis is finished, rising a temperature, performing stirring extraction and solid-liquid separation on the rhizoma polygonati odorati to acquire an extracting solution, and performing concentration on the extracting solution; and (3) alcohol precipitation: performing mixing, standing and solid-liquid separation operation on a concentrated solution and anhydrous ethanol, and drying precipitates obtained with separation to obtainthe polygonatum odoratum polysaccharide. The extraction method has the advantages of high polysaccharide extraction rate, good purity, small energy consumption, low cost and the like; and the polysaccharide extractive has the advantages of good purity and high nutrition and health care value.

Description

technical field [0001] The invention relates to the field of extraction of traditional Chinese medicines, in particular to a method for extracting Polygonatum polysaccharide and Polygonatum polysaccharide extract. Background technique [0002] The traditional Chinese medicine Polygonatum Polygonatum, also known as Vitiligo, is the dry rhizome of Polygonatum modoratum (Mill.) Druce, a plant of the genus Polygonatum in the family Liliaceae. It tastes sweet and slightly bitter, and is flat and slightly warm in nature. This medicine nourishes yin and nourishes the lungs, nourishes the stomach and promotes body fluids, and has the effects of nourishing and health care, and both medicine and food. "Shen Nong's Materia Medica", "Compendium of Materia Medica" and other traditional Chinese medicine classics are listed as top grade. Modern medical research shows that Yuzhu has the functions of strengthening the heart, dilating blood vessels, lowering blood pressure, lowering blood su...
