Abstract
The invention discloses an extraction method of a Chinese herbal medicine, and belongs to the technical field of Chinese herbal medicine application. The method comprises the following steps: heating an extract solvent until boiling, and pouring into an extraction tank containing to-be-treated Chinese herbal medicines which are soaked with the extract solvent in advance; heating the extraction tank in the step A with an external fire source, simultaneously collecting a gas generated in the heating process until the Chinese herbal medicines in the extraction tank are completely carbonized, and stopping heating; condensing and recovering the gas collected from the step B to obtain a Chinese herbal medicine extract liquid; adding the Chinese herbal medicine extract liquid prepared from the step C into an extract solution again; and mixing evenly, standing, filtering, collecting a supernatant, and carrying out vacuum evaporation on the supernatant to obtain a Chinese herbal medicine extract. The extraction method of the Chinese herbal medicine has the advantages that the used solvents are few, the extraction time is short and the extracted active ingredients are high in purity.
Description
Technical field
The invention belongs to Chinese herbal medicine applied technical field, particularly relate to a kind of extracting method of Chinese herbal medicine.
Background technology
China is the cradle of Chinese herbal medicine, at present the nearly 12000 kinds of medicinal plants of China, and this is not available for other countries.
Application in TCM Theory comparison is unique.Chinese medicine has four natures and five flavors of drug, and four gas, also known as four property, refer to the cold, hot, warm, cool of the property of medicine; The five tastes refer to the pungent, sour, sweet, bitter, salty of medicine.Gas, the taste of Chinese herbal medicine are different, and its curative effect is also different.
The application form of Chinese herbal medicine is varied, and useful medicine adds water to remove slag after fry cooked and stays the decoction of juice, has the powder be ground into powder, also has pill, unguentum, medicated wine, tablet, electuary, injection etc.
The convenience used to make Chinese herbal medicine and the maximization of effect, people start medium-height grass the effective elements of the medicine to extract, and then make various medicament by extracting the effective ingredient obtained.General Chinese herbal medicine extracting method has infusion process, percolation, reflux extraction etc., and it is large that these method ubiquities use solvent, and the time is long, the problem that impurity is many.
Summary of the invention
The invention provides a kind of extracting method of Chinese herbal medicine, the solvent that the extracting method of this Chinese herbal medicine uses is few, and extraction time is short, extracts the effective ingredient purity obtained high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
An extracting method for Chinese herbal medicine, the method comprises the following steps:
A, Extraction solvent is heated to boiling, then pours in the extraction pot that the pending Chinese herbal medicine soaked with Extraction solvent is in advance housed;
B, to heat with the extraction pot of outside burning things which may cause a fire disaster to steps A, collect the generation gas in its heating process simultaneously, until the complete carbonization of Chinese herbal medicine in extraction pot, stop heating;
C, the gas collected by step B reclaim through condensation, obtain Chinese herbal medicine crude extract;
D, in the obtained Chinese herbal medicine crude extract of step C, rejoin extraction solution, mix homogeneously, leave standstill, filter, collect supernatant, and by described supernatant vacuum evaporation, obtain the extract of Chinese herbal medicine.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
1. to extract the quantity of solvent of use few in the present invention, and extraction time is short.
2. to extract the effective ingredient purity obtained high in the present invention, and the impurity contained is few.
