Embodiment 1

[0032] The first step: pretreatment: 25Kg of dried leaves of Eucommia ulmoides (3.42% of glue content) is properly pulverized, added 12 times of water, refluxed at 100°C for 2 extractions, separated from solid and liquid, and dried to obtain 7.05Kg of Eucommia instant tea powder.

[0033] The second step: the slag absorbs nutrients with edible fungi and destroys the cell wall: the slag is placed in an exposed environment and stacked into a cuboid with a height of 60cm, so that the temperature in the center of the pile is gradually raised to about 50°C. When Eucommia 1# mycelium grows, spread out the material pile and stack it into about 1Kg per portion, so that the edible fungus can absorb the unremoved water-soluble components, fully decompose, destroy the cell wall and absorb nutrients. After 7 days, collect Eucommia 1# edible fungus, and use the residue for later use.

[0034] The third step: extraction of eucommia gum: the residue is extracted with petroleum ether, refined...

Embodiment 2

[0036] The first step: pretreatment: 25Kg of dried bark of Eucommia ulmoides (6.51% of glue content) is properly pulverized, added with 6 times of water, refluxed at 60°C for 3 times, separated from solid and liquid, and dried to obtain 7.46Kg of Eucommia instant tea powder.

[0037] The second step: the slag absorbs nutrients with edible fungi and destroys the cell wall: the slag is piled up into a cone with a height of 80cm, and the temperature in the center of the pile is gradually raised to about 50°C, inoculated with Pleurotus ostreatus, and the pile is scattered, Pile it up into about 5Kg per portion, so that the oyster mushrooms can grow, absorb the unremoved water-soluble components, fully decompose, destroy the cell wall and absorb nutrients. Collect Pleurotus ostreatus after 6 days, and the residue is for subsequent use.

[0038] The third step: extraction of eucommia gum: the residue is extracted with petroleum ether, refined, and dried to obtain 1.46Kg of eucommia ...

Embodiment 3

[0040] The first step: pretreatment: 25Kg Eucommia fruit (10.12% glue content) is crushed appropriately, adds 10 times of water, 80 DEG C reflux extraction twice, solid-liquid separation, liquid drying, obtains Eucommia instant tea powder 6.28Kg.

[0041] The second step: the slag absorbs nutrients with edible fungi and destroys the cell wall: the slag is piled into a cuboid with a height of 70cm, and the temperature in the center of the pile is gradually raised to about 50°C. About 3Kg per serving, so that Flammulina velutipes grows, absorbs unremoved water-soluble components, fully decomposes, destroys cell walls and absorbs nutrients. Collect Flammulina velutipes after 10 days, and the residue is for subsequent use.

[0042] The third step: extraction of eucommia gum: the residue is extracted with petroleum ether, refined, and dried to obtain 2.25Kg of eucommia gum.

Abstract

The invention relates to a method for extracting a natural product from folium cortex eucommiae, skin or fruit, and particularly relates to a method for extracting gutta-percha from folium cortex eucommiae, skin or fruit. The method comprises the following processing steps: 1, pretreatment of the folium cortex eucommiae, skin or fruit, including drying, crushing and extracting of a water-soluble component; 2, decomposing slag by edible fungi, absorbing nutrition, destroying a cell wall, including breeding or inoculating of the edible fungi, and absorbing of nutrition; and 3, extracting the gutta-percha, including extracting, refining and drying. The method is high in production efficiency; and not only can instant tea powder be extracted to prepare the gutta-percha from the folium cortex eucommiae, skin or fruit, but also the edible fungi with abundant nutritive value can be cultivated by using the waste slag, so that comprehensive utilization of the folium cortex eucommiae, skin or fruit is achieved; the material cost for extracting the gutta-percha is diluted. Meanwhile, the volume of the material before extraction of the gutta-percha is greatly reduced, so that the dosage of the solvent in extraction of the gutta-percha is reduced; the production cost of the gutta-percha is greatly reduced.

Description

technical field [0001] The invention relates to a method for extracting natural products from eucommia leaves, bark or fruit, in particular to a method for extracting eucommia gum from eucommia leaves, bark or fruit. Background technique [0002] With the development of my country's automobile industry and tire industrial-grade rubber-related fields, my country has become the world's largest consumer of natural rubber, with an annual consumption of more than 3 million tons. However, due to the limitation of geographical environment, the domestic production is limited, and the import dependence is more than 80%. In recent years, the price of natural rubber has continued to rise, and even broke through the historical high of 40,000 / ton in early 2011, which has brought huge cost pressure to rubber processing enterprises such as tires. The situation of long-term high dependence on imports and rising rubber has seriously affected and restricted the stable and safe development of...
