Embodiment 1

[0122] This embodiment provides a method for extracting active components of licorice when the flow direction of the mixed medicinal solution is the same as the direction in which the electrode pair is arranged from the positive electrode to the negative electrode. The schematic diagram of the extraction device of licorice is as follows figure 1 As shown, the steps of licorice extraction are as follows:

[0123] 1) 25g licorice is pulverized through a 10 mesh sieve to obtain licorice powder (particle size is 2mm), 500mL of water and licorice powder are stirred and mixed to make mixed medicinal liquid, and the concentration of licorice powder is 0.05g / mL;

[0124] 2) The liquid medicine pipeline is set vertically, and the mixed liquid medicine is transported to the middle of the electrode pair through the peristaltic pump. The flow rate of the mixed liquid medicine is 150mL / s, and the flow direction of the mixed liquid medicine is the same as that of the electrode pair from pos...

Embodiment 2

[0129] The present embodiment provides a method for extracting active ingredients of licorice when the flow direction of the mixed medicinal solution is opposite to the direction in which the electrode pair is arranged from the positive electrode to the negative electrode. The schematic diagram of the licorice extraction device is as follows figure 2 As shown, the steps of licorice extraction are as follows:

[0130] 1) 35g licorice is sieved through a 10 mesh sieve to obtain licorice powder (particle size is 2mm), 500mL of water and licorice powder are stirred and mixed to make mixed medicinal liquid, and the concentration of licorice powder is 0.07g / mL;

[0131] 2) The liquid medicine pipeline is set vertically, and the mixed liquid medicine is transported to the middle of the electrode pair through the peristaltic pump. The flow rate of the mixed liquid medicine is 170mL / s. The flow direction of the mixed liquid medicine is opposite to the direction of the current between ...

Embodiment 3

[0136] This embodiment provides a method for extracting the active components of Gardenia when the flow direction of the mixed medicinal solution is the same as the direction in which the electrode pair is arranged from the positive electrode to the negative electrode. The schematic diagram of the extraction device of gardenia is as follows figure 1 As shown, the steps of gardenia extraction are as follows:

[0137]1) 25g gardenia is pulverized through 10 mesh sieves to obtain gardenia powder (particle size is 2mm), 500mL of water and gardenia powder are stirred and mixed to make mixed medicinal liquid, and the concentration of gardenia powder is 0.05g / mL;

[0138] 2) The liquid medicine pipeline is set vertically, and the mixed liquid medicine is transported to the middle of the electrode pair through the peristaltic pump. The flow rate of the mixed liquid medicine is 150mL / s, and the flow direction of the mixed liquid medicine is the same as that of the electrode pair from p...

Abstract

The embodiment of the invention discloses a method for extracting effective components in dicotyledon, which comprises the following steps: mixing dicotyledon powder with a solvent to obtain a mixed liquid medicine; enabling the mixed liquid medicine to flow through the electrode pairs along a direction parallel to the arrangement direction of one or more electrode pairs of the high-voltage electric field, and performing single extraction or multiple times of cyclic extraction to obtain an extracting solution containing the effective components. By adopting the method disclosed by the embodiment of the invention, the effective components in the traditional Chinese medicine decoction pieces of liquorice or gardenia can be efficiently extracted in a short time in a normal-temperature state, the extraction efficiency of the traditional Chinese medicine decoction pieces of liquorice or gardenia is improved, the extraction time and the energy cost are saved, and meanwhile, the content of the extracted effective components is ensured to be consistent with that of water decoction.

Description

technical field [0001] The present application relates to the technical field of medicine, in particular to a method for extracting active ingredients from dicotyledonous plants. Background technique [0002] With the in-depth research on the active ingredients of traditional Chinese medicine, its application scope has become more and more extensive, and the demand has increased year by year. Among dicotyledonous plants, licorice and gardenia are very important medicinal materials. Licorice is the dried roots and rhizomes of licorice, licorice, and licorice. It is a commonly used bulk medicinal material, and has the reputation of "nine herbs in ten directions" and "old country". It is widely used in Chinese herbal decoction pieces, Chinese patent medicines and Licorice extract and other fields. Gardenia is the dried and ripe fruit of the Rubiaceae plant Gardenia. It is a traditional Chinese medicine commonly used in clinical practice. It is also one of the first batch of m...
