Embodiment 1

[0028] This embodiment is a method for efficiently extracting the active ingredients of traditional Chinese medicine by the freeze-thaw method. The method includes and preferably operates according to the following steps:

[0029] Step S11, pulverizing the raw material of traditional Chinese medicine into a powder of 10-200 mesh; powder A, the thickness of the powder depends on the type of the original medicine and the subsequent temperature change;

[0030] Step S12, put the powder A in the environment of -40°C to -20°C for the first freezing, until the internal and external temperatures of the powder A are consistent, and then place it in the environment of -40°C to -20°C for 0.1min to 1min, then gradually raise the temperature to bring powder A back to normal temperature, during this process, make powder A absorb water naturally; after staying at normal temperature for 24h, powder B is obtained;

[0031] Step S13, put the powder B in the environment of -40°C to -10°C for th...

Embodiment 2

[0035] This embodiment is a method for efficiently extracting the active ingredients of traditional Chinese medicine by the freeze-thaw method. The method includes and preferably operates according to the following steps:

[0036] Step S21, pulverizing the raw material of traditional Chinese medicine into a powder of 10-200 mesh; powder A, the thickness of the powder depends on the type of the original medicine and the subsequent temperature change;

[0037] Step S22, put the powder A in the environment of -20°C to 0°C for the first freezing until the internal and external temperatures of the powder A are consistent, and then place it in the environment of -20°C to 0°C for 20min to 30min, Then gradually raise the temperature to make powder A return to normal temperature. During this process, powder A naturally absorbs water; after staying at normal temperature for 15 hours, powder B is obtained; in this step, if it is in a particularly dry area or season, you can While making ...

Embodiment 3

[0042] This embodiment is a method for efficiently extracting the active ingredients of traditional Chinese medicine by the freeze-thaw method. The method includes and preferably operates according to the following steps:

[0043] Step S31, pulverizing the raw material of traditional Chinese medicine into a powder of 10-200 mesh; powder A, the thickness of the powder depends on the type of the original medicine and the subsequent temperature change;

[0044] Step S32, put the powder A in the environment of -10°C to 0°C for the first freezing until the internal and external temperatures of the powder A are consistent, then place it in the environment of -10°C to 0°C for 60 minutes, and then gradually Raise the temperature to return powder A to normal temperature. During this process, powder A naturally absorbs water; after staying at normal temperature for 0.5h, powder B is obtained; in this step, if it is in a particularly dry area or season, it can be used if necessary While ...

Abstract

The invention discloses a method for effectively extracting active ingredients of a traditional Chinese medicine and belongs to an extraction method. The method comprises the following steps: crushing raw materials of the traditional Chinese medicine into powder with 10 to 200 meshes to obtain powder A; putting the powder A in the environment of 40 DEG C below zero to 0 DEG C and carrying out first-time freezing until the internal temperature of the powder A is consistent with the external temperature of the powder A, then putting the powder A in the environment of 40 DEG C below zero to 0 DEG C for 0.1 to 60 minutes, and gradually raising the temperature of the powder A to normal temperature, and enabling the powder A to naturally absorb water in the process; staying at normal temperature for 0.5 to 24 hours to obtain powder B. Water infiltrating into cells is condensed into ice crystals when the water freezes again by carrying out two-time freezing and dissolving on crushed powder and ingeniously utilizing the characteristic that low-temperature powder naturally absorbs the water; the cell wall of an active drug can be effectively destroyed by the ice crystals, so that the extraction rate of active ingredients of plants is greatly improved, and the extraction time and extraction times can be effectively reduced; the method is particularly suitable for extracting the active ingredients of high-value traditional Chinese medicine or other precious plants.

Description

technical field [0001] The invention relates to an extraction method, more specifically, the invention mainly relates to a method for efficiently extracting active ingredients of traditional Chinese medicines by using a freeze-thaw method. Background technique [0002] As traditional Chinese medicine goes to the world, traditional Chinese medicine preparations are also increasingly westernized. More and more traditional Chinese medicines need to extract active (effective) ingredients to make more convenient tablet or capsule dosage forms. For the processing of original medicines with similar acquisition costs, the extraction efficiency (extraction rate, yield) of active (active) ingredients is the most critical step that affects production costs. Therefore, all pharmaceutical companies are committed to extracting the active ingredients of the original medicine as efficiently as possible, and have developed many related technologies and processes, but the extraction efficien...
