Embodiment 1

[0024] Acanthopanax 500g, pretreated, impurity removed, dried until the water content is not higher than 20%, coarsely crushed to 60 mesh, added 10g of Na 2 CO 3 , crushed by planetary mill to get processed powder N 1 .

[0025] Weigh each portion of 5g processed powder N 1 60 meshes of Acanthopanax senticosus (GC) were conventionally crushed, respectively added with 50 ml of distilled water and 20% ethanol, and extracted at room temperature for 48 hours. After filtering with gauze and absorbent cotton, place the water extract and 20% alcohol extract in a 50°C water bath to evaporate to dryness, and weigh them respectively.

Embodiment 2

[0027] Acanthopanax 500g, pretreated, impurity removed, dried until the moisture content is not higher than 20%, coarsely crushed to 60 mesh, added 20g of NaHCO 3 , crushed by planetary mill to get processed powder N 2 .

[0028] Weigh each 5g processing powder N 2 60 meshes of Acanthopanax senticosus (GC) were conventionally crushed, respectively added with 50 ml of distilled water and 20% ethanol, and extracted at room temperature for 48 hours. After filtering with gauze and absorbent cotton, place the water extract and 20% alcohol extract in a 50°C water bath to evaporate to dryness, and weigh them respectively.

Embodiment 3

[0030] Acanthopanax 500g, pretreated, impurity removed, dried until the water content is not higher than 20%, coarsely crushed to 60 mesh, added 5 grams of NaOH, crushed by a planetary mill, and processed powder N 3 .

[0031] Weigh each portion of 5g processing powder N 3 60 meshes of Acanthopanax senticosus (GC) were conventionally crushed, respectively added with 50 ml of distilled water and 20% ethanol, and extracted at room temperature for 48 hours. After filtering with gauze and absorbent cotton, place the water extract and 20% alcohol extract in a 50°C water bath to evaporate to dryness, and weigh them respectively.

Abstract

The invention discloses a plant active component extraction method. The plant active component extraction method comprises crushing extracted plant raw materials to obtain crude powder, adding 0.5-20% of a chemical auxiliary agent such as solid alkali, solid acid, cane sugar or salt compound powder into the crude powder, carrying out mechanical pulverization, dissolving the crushed materials by water or ethanol, carrying out separation and collecting a soluble component as an active component.

Description

technical field [0001] The invention belongs to the field of biotechnology and relates to a method for extracting effective plant components. Background technique [0002] The active ingredients of plant medicine usually exist in the vacuoles in the cell protoplasm. When the cells are intact, the solvent must first infiltrate the plant surface, then penetrate the cell wall and cell membrane, enter the cell tissue, dissolve the active ingredients, and form a concentration difference inside and outside the cell. The high-concentration leachate is forced to diffuse from the inside to the outside, and the dilute leachate or fresh solvent replaces the concentrated leachate at any time to complete a leaching process. This is the basic principle of extracting active ingredients by conventional methods such as maceration, percolation, Soxhlet reflux extraction, and dynamic extraction. The complete cell wall and cell membrane will form resistance to the release of active ingredients,...
