Abstract

The invention discloses a Eucommia ulmoides rubber refining method. The method comprises the following steps: 1, preprocessing Eucommia ulmoides leaves, and sequentially removing chlorophyll, beta-carotene, lignans, aucubins, chlorogenic acid, proteins, flavones and polysaccharide compounds from the Eucommia ulmoides leaves; 2, extracting Eucommia ulmoides rubber by adopting petroleum ether; and 3, adding a precipitating agent to a petroleum ether extract liquid obtained in step 2, and allowing the obtained mixture to stand for precipitation to obtain the Eucommia ulmoides rubber. The Eucommia ulmoides rubber obtained by refining through the method has a light color, solves a problem that the export of the Eucommia ulmoides rubber is limited because of the dark color, and has the advantages of low extraction cost, almost zero cost of the raw material, less energy consumption, small solvent loss, and high circulating utilization rate. A new reference direction is provided for the industrialized production.

Description

technical field

[0001] The invention relates to a method for refining natural resin, in particular to a method for refining natural plant eucommia by means of extraction. Background technique

[0002] Eucommia ulmoides (Eucommia Ulmoides) is a deciduous tree belonging to Eucommiaceae. It is a rare and precious economic tree species unique to my country, an important light industrial material, and an important gum source tree species with the most development prospects in subtropical and warm temperate zones. As a precious Chinese medicinal material, Eucommia ulmoides leaves and bark contain a variety of medicinal substances. The bark can be used as medicine, and the leaves can be used to make health tea and various beverages. The history of use can be traced back to the "Shen Nong Mucao Jing" in the second century AD. Modern studies have shown that Eucommia Ulmoide Gum (EUG), which is rich in white filamentous gum (Eucommia Ulmoide Gum, EUG) in leaves, bark and seeds, is int...
