Problems solved by technology

[0003] However, the existing ethanol precipitation method consumes a large amount of ethanol, and in the process of adding ethanol solution, the concentration of local ethanol is too high, causing the precipitate to wrap the active ingredient, causing the loss of the active ingredient, and also causing the precipitate sticky, difficult to separate by filtration

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] As shown in the figure, the present invention provides an alcohol precipitation method for automatically absorbing the supernatant, including the following steps,

[0022] (1) importing the Chinese medicine extract into the retort, and concentrating the Chinese medicine extract to an initial ointment concentration of 30%-60%;

[0023] (2) Import the initial ointment generated in the first step into the alcohol precipitation tank, and let it stand at 5-10°C for 10-24h until the temperature in the Chinese medicine extract reaches 5-10°C. Nozzle;

[0024] (3) According to the volume-to-number ratio, select 80-100 parts of the initial ointment, select 20-40 parts of ethanol solution with an alcohol content greater th...

Abstract

The invention provides an alcohol precipitation method capable of automatically absorbing supernatant, and relates to the field of traditional Chinese medicine alcohol precipitation. A traditional Chinese medicine extracting solution is concentrated until the concentration of primary paste is 30-60% in advance, so that the subsequent ethanol solution for alcohol precipitation diluted by the traditional Chinese medicine extracting solution can be effectively reduced, then the primary paste is cooled to 5-10 DEG C, the volatilization of the subsequent ethanol solution can be reduced, and the ethanol solution is added according to different concentrations, thereby effectively preventing the concentration of local ethanol from being too high; the alcohol precipitation effect of the supernatantcan be effectively improved by avoiding the loss of the effective components due to the fact that the effective components are wrapped by the precipitates.

Description

technical field [0001] The invention relates to the field of alcohol precipitation of traditional Chinese medicines, in particular to an alcohol precipitation method for automatically absorbing supernatant. Background technique [0002] In the production process of traditional Chinese medicine, the alcohol precipitation method (ethanol precipitation method) is commonly used to purify and refine the water extract of traditional Chinese medicine. The active ingredients are extracted, and many water-soluble impurities are extracted at the same time. The alcohol precipitation method uses the characteristics that the active ingredients can be dissolved in ethanol and the impurities are insoluble in ethanol. After adding ethanol, the active ingredients are dissolved in ethanol and the impurities The purpose of alcohol precipitation is to remove impurities and retain the active ingredients of the drug, so the applicability of the alcohol precipitation operation process and equipmen...
