Embodiment 1

[0036] a. Collect 100 grams of Elaeagnus eraefolia gum from August to September every summer, and then dry it naturally in a cool place and then crush it with a stainless steel shaker screw type small grinder. The crushing time is 60 seconds, and a round stainless steel mesh is used. Sieve and filter 100 mesh, separate impurity, obtain gum powder;

[0037] b. The gum powder obtained in step a is prepared with distilled water to form a gum solution with a concentration of 0.1%;

[0038]c. Heat the gum solution in step b to dissolve the gum on the electric heating mantle, and centrifuge at a speed of 1000r / min for 2 minutes while keeping warm, separate and remove mechanical impurities and organic impurities, and obtain the gum solution for subsequent use;

[0039] d. Heating the gum solution in step c to a temperature of 80° C., stirring and adding hydrochloric acid with a volume concentration of 8% dropwise, and then decolorizing with hydrogen peroxide with a volume concentrati...

Embodiment 2

[0042] a. Collect 100 grams of Elaeagnus eraefolia gum from August to September every summer, dry it naturally in the shade, and then crush it with a stainless steel screw-type small grinder. The crushing time is 80 seconds, and the round stainless steel is used. Filter 200 meshes through a mesh sieve to separate foreign matter to obtain gum powder;

[0043] b. The gum powder obtained in step a is prepared with distilled water to form a gum solution with a concentration of 2%;

[0044] c. Heat the gum solution in step b to dissolve the gum on the electric heating mantle, and centrifuge at a speed of 5000r / min for 3 minutes in a state of heat preservation, separate and remove mechanical impurities and organic impurities, and obtain the gum solution for subsequent use;

[0045] d. Heat the gum solution in step c to a temperature of 80° C., add hydrochloric acid with a concentration of 8% dropwise with stirring, and then treat it with hydrogen peroxide with a volume concentration...

Embodiment 3

[0048] a. Collect 100 grams of Elaeagnus eraefolia gum from August to September every summer, dry it naturally in the shade, and then crush it with a small stainless steel screw-type grinder. The crushing time is 100 seconds, and the round stainless steel is used. Filter 300 meshes with a mesh sieve to separate foreign matter to obtain gum powder;

Abstract

The invention relates to a method for preparing elaeagnus angustifolia gum polysaccharide.According to the method, elaeagnus angustifolia gum collected in summer is dried naturally, smashed mechanically and sieved so that impurities can be separated out, a gum water solution is prepared, heating, temperature keeping, centrifugal separating, reheating, stirring and hydrochloric acid adding in a dropwise mode are conducted, acetone is added after hydrogen peroxide processing to obtain precipitate, the precipitate is flushed with acetone and filtered to obtain polysaccharide precipitate, low-temperature or vacuum drying or freeze drying is conducted on the polysaccharide precipitate, filtering and smashing are conducted, and white elaeagnus angustifolia gum polysaccharide powder is obtained.By means of the method, the yield of the total polysaccharide obtained through extraction reaches 90% or above, very good water solubility is achieved, and the water solution has very good light transmittance and high-strength viscosity; the physicochemical property of the elaeagnus angustifolia gum polysaccharide is retained; meanwhile, to a certain degree, the method provides a scientific basis for analyzing the material base of the hair care cosmetic secrete recipe elaeagnus angustifolia gum used in traditional folk in SinKiang.

Description

technical field [0001] The invention relates to a preparation method of pear gum polysaccharide. [0002] Background technique: [0003] Elaeagnus angustifolia L. and Elaeagnus angustifolia L. (E.oxycarpa Schlecht.) are plants of the genus Elaeagnus angustifolia. They grow in semi-arid, arid, semi-desert, and desert areas. They are "treasures" in deserts. Tree". It is distributed in the United States, Canada, the Mediterranean coast, Iran, West Asia, and India. In my country, Xinjiang, Qinghai, Gansu, western Inner Mongolia, and Ningxia have relatively large growth areas and high yields. It is also distributed in some provinces in Hebei, Henan, and Northeast China. According to statistics, the total area of ​​Elaeagnus sativa forest in my country is about 2 million mu. Eleuthero jujuba is an economical tree species with multiple functions. It has health effects such as "strengthening, calming, invigorating the stomach, stopping diarrhea, and diuresis". At present, it is wi...
