Embodiment 1

[0164] Take Chuanxiong decoction pieces and moisten with 70% ethanol for 15 minutes;

[0165] Add 70% ethanol to soak in the decoction pieces after wetting for 24 hours;

[0166] Place the soaked medicinal material decoction pieces in a percolation tank, add 8 times the solvent of the medicinal material, and perform percolation at a speed of 100ml / min / kg medicinal material;

[0167] Collect the percolate and remove the solvent to obtain the extract of Rhizoma Chuanxiong.

Embodiment 2

[0169] Take Radix Paeoniae Alba and crush it into decoction pieces, moisten with 80% ethanol for 15 minutes;

[0170] Add 80% ethanol to soak in the decoction pieces after wetting for 24 hours;

[0171] Place the soaked medicinal material decoction pieces in a percolation tank, add 8 times the solvent of the medicinal material, and percolate at a speed of 185ml / min / kg medicinal material;

[0172] Collect the percolate and remove the solvent to obtain the Radix Paeoniae Alba extract.

Embodiment 3

[0174] Take Bupleurum bupleuri and wet it with 70% ethanol for 15 minutes;

[0175] Add 70% ethanol to the wetted medicinal materials and soak for 24 hours;

[0176] Place the soaked medicinal material in a percolation tank, add 8 times the amount of medicinal material solvent, and perform percolation at a speed of 185ml / min / kg medicinal material;

[0177] Collect the percolate and remove the solvent to obtain the Bupleurum extract.

Abstract

The invention relates to a method for efficiently extracting effective compositions of traditional Chinese medicines through percolation, and especially relates to a method for efficiently extracting effective compositions of ligusticum wallichii, radix paeoniae alba, radix bupleuri, forsythia suspensa, panax pseudoginseng, angelica dahurica, curcuma longa and other traditional Chinese medicines through percolation. The extraction method comprises the following steps: 1) taking a traditional Chinese medicinal material, and wetting by using a solvent; 2) adding a solvent into the wet traditional Chinese medicinal material for immersing; 3) performing percolation on the immersed traditional Chinese medicinal material by using a solvent; and 4) collection the percolation liquid, and removing the solvent to obtain the traditional Chinese medicine extractive.

Description

technical field [0001] The invention relates to a percolation extraction method of effective components of traditional Chinese medicinal materials, in particular to a rapid percolation extraction method of effective components of traditional Chinese medicines such as Rhizoma Chuanxiong, Paeoniae Alba, Bupleurum, Forsythia, Panax notoginseng, Angelica dahurica, Turmeric and the like. Background technique [0002] The percolation method is a leaching method in which a leaching solvent is continuously added to the coarse powder of the medicine to make it permeate the powder, and the leaching solution is continuously flowed out from the outlet of the lower end. During percolation, the solvent infiltrates into the cells of medicinal materials to dissolve a large amount of soluble substances, the concentration increases, the density increases and moves downward, and the leaching solvent or dilute infusion in the upper layer replaces the position, resulting in a good concentration d...
