AI Technical Summary

Technical Problem

The existing extraction and separation processes have problems such as low efficiency, long time, large solvent usage and great environmental impact. At the same time, the traditional purification methods take a long time and are not effective, which can easily cause blockage.

Method used

Combining ultrafine crushing technology and reverse application process, efficient extraction and separation and purification are achieved through multi-stage cold-pumping process and dynamic crystal filtration process. This method reduces the amount of solvent, improves the extraction efficiency and extract concentration, and shortens the extraction time.

Benefits of technology

Efficient extraction of plant active ingredients at room temperature or low temperature conditions in a short period of time has significantly improved the extraction efficiency and purity, reduced the cost of solvent use and subsequent treatment, and is suitable for industrial production.

Abstract

The invention belongs to the technical field of extraction and separation of active ingredients, and particularly relates to a method for extracting, separating and purifying plant active ingredients. The method comprises the following steps: processing a pretreated plant raw material to a target particle size to obtain plant particles to be extracted; the solvent is input into a first-stage cold extraction section in a multi-stage cold extraction process, the plant particles to be extracted are input into n-stage cold extraction sections, and n is an integer greater than 1, preferably 2; mixing in a cold extraction section, carrying out solid-liquid separation in a corresponding solid-liquid separation section after the extraction is completed, enabling an obtained extracting solution to enter a next-stage cold extraction section, and enabling residues to enter a previous-stage cold extraction section; and discharging the extracting solution An from an n-stage solid-liquid separation section, and separating and purifying through a dynamic crystal filtration section to obtain a target product purified solution Cn. The method disclosed by the invention is simple in process, short in time consumption, environment-friendly, high in extraction efficiency, good in final product purity and suitable for industrial production, and the use of an organic solvent can be reduced or is not used.
