A method for extracting and separating eucommia gum from the feces of eucommia ulmoides larvae

Abstract

The invention belongs to the technical field of extraction and separation of eucommia gum, a natural product, and discloses a method for extracting and separating eucommia gum from eucommia ulmoides larvae feces. Put it in a dry and cool place to dry; mechanically pulverize the dried feces of eucommia ulmoides larvae, and dry in vacuum; put the processed raw materials in a blender, and heat them in a water bath; dry the separated filter residue, and use Decolorize with acetone, filter, and dry; remove impurities to obtain bioactive components; mix the dried filter residue with petroleum ether, reflux extraction, filter to remove impurities, and precipitate to obtain Eucommia Gum. The invention has few extraction process steps, convenient operation, and short extraction and separation time; the obtained extract has high purity, and the precipitated eucommia gum has good color, which effectively reduces the cost in the development process of eucommia gum, and realizes the eucommia ulmoides larva The efficient utilization of Eucommia has promoted the diversified development of Eucommia industry.

Description

technical field

[0001] The invention belongs to the technical field of extraction and separation of eucommia gum, a natural product, and in particular relates to a method for extracting and separating eucommia gum from excrement of eucommia ulmoides larvae. Background technique

[0002] At present, Eucommia ulmoides Oliver is a plant of Eucommia genus Eucommia (Eucommiaceae) and is a deciduous tree of a single family. Eucommia ulmoides is rich in flavonoids, phenylpropanoids, lignans, iridoids and other secondary metabolites that have the functions of anti-oxidation, lowering blood pressure, lowering blood sugar, and enhancing immunity. It is a unique and precious medicinal plant . In addition to being used for medicine, Eucommia ulmoides can also be extracted from Eucommia ulmoides, a natural polymer compound. Eucommia ulmoides gum has excellent properties such as shape memory, low-temperature plasticity, corrosion resistance, wear resistance, sound insulation, and shock a...
