Embodiment 1

[0071] This embodiment provides a method for extracting active components of Scutellaria baicalensis when the flow direction of the mixed medicinal solution is the same as the direction in which the electrode pair is set from the positive electrode to the negative electrode. Schematic diagram of Scutellaria baicalensis extraction device figure 1 Shown, the step that Huang Cen extracts is as follows:

[0072] 1) Pulverize 25g of Radix Scutellariae through a 10-mesh sieve to obtain Rhizoma Rhizoma Rhizoma Rhizoma Scutellariae powder (particle size is 2mm), stir and mix 500mL of water and Rhizoma Rhizoma Rhizoma Rhizoma Rhizoma Rhizome powder evenly to make mixed medicinal liquid, the concentration of Rhizoma Rhizoma Rhizoma Rhizome powder is 0.05g / mL;

[0073] 2) The liquid medicine pipeline is set vertically, and the mixed liquid is transported to the middle of the electrode pair through the peristaltic pump. 1~3kv high voltage makes the mixed medicinal solution pass through a...

Embodiment 2

[0078] This embodiment provides a method for extracting active components of Scutellaria baicalensis when the flow direction of the mixed medicinal solution is opposite to the direction in which the electrode pair is set from the positive electrode to the negative electrode. Schematic diagram of Scutellaria baicalensis extraction device figure 2 Shown, the step that Huang Cen extracts is as follows:

[0079] 1) Pass 35g of Scutellaria Scutellariae through a 5-mesh sieve to obtain Scutellaria Scutellariae powder (particle size is 4mm), stir and mix 500mL of water and Scutellaria Scutellariae powder evenly to make a mixed liquid, the concentration of Scutellaria Scutellariae powder is 0.07g / mL;

[0080] 2) The liquid medicine pipeline is set vertically. The mixed liquid is transported to the middle of the electrode pair through the peristaltic pump. The flow rate of the mixed liquid is 170mL / s. The mixed medicinal solution is continuously extracted at 25°C under a flowing stat...

Abstract

The embodiment of the invention discloses an extraction method of active ingredients of radix scutellariae, which comprises the following steps: mixing radix scutellariae powder with a solvent to obtain a mixed liquid medicine; exposing the mixed liquid medicine in a high-voltage electric field, enabling the mixed liquid medicine to flow along the direction parallel to the arrangement direction of the electrode pair in the high-voltage electric field, and circulating for 1-6 times to obtain an extracting solution containing the active ingredient of the radix scutellariae. By adopting the method disclosed by the embodiment of the invention, the effective components in the traditional Chinese medicine decoction piece scutellaria baicalensis can be efficiently extracted in a short time in a normal-temperature state, the extraction efficiency of the traditional Chinese medicine decoction piece scutellaria baicalensis 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 application relates to the technical field of medicine, in particular to a method for extracting effective components of Scutellaria baicalensis. Background technique [0002] With the in-depth research on the active ingredients of traditional Chinese medicine, its application scope has become wider and wider, and the demand has increased year by year. Scutellaria Scutellariae has the functions of clearing away heat and dampness, purging fire and detoxification, hemostasis and anti-pregnancy. It also has a good therapeutic effect on symptoms such as lung-heat cough, damp-heat jaundice, pneumonia, dysentery and hemoptysis. Cold is one of the common diseases in people. 1. Scutellaria chinensis is one of the main materials in the medicine for treating colds. [0003] The traditional Chinese medicine decoction of Scutellaria scutellaria mainly uses water decoction to extract the active ingredients of Scutellaria scutellariae, but there are disadvantag...
