Abstract

The invention discloses a plant extraction and purification process, and relates to the technical field of plant extraction. The extraction and purification process comprises the following steps: cleaning, drying and crushing a to-be-extracted plant, adding a 50-70% ethanol solution, carrying out alcohol extraction to obtain an alcohol extracting solution, feeding the alcohol extracting solution into a macroporous resin column, after adsorption is completed, washing with deionized water with the volume 1-2 times that of the column to remove impurities, eluting with a 60-70% ethanol solution, collecting eluent, concentrating under reduced pressure to obtain extract with the relative density of 1.10-1.15, adding ethanol into the obtained extract, stirring, fully dissolving, standing, filtering, collecting filtrate to obtain purified extracting solution, and filtering the purified extracting solution with an ultrafiltration membrane to obtain a refined extracting solution. The plant extraction and purification process can effectively separate impurities in an extracting solution so as to improve the purity of active ingredients, and does not use any organic solvent in the whole extraction process, so that the product is safer and more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a plant extraction and purification process. Background technique [0002] With the development of our country's economy and the improvement of people's living standards, people are increasingly recognizing the life philosophy of "pursuing nature and advocating nature". The health care effect of natural food has attracted much attention, and the plant extract industry has become the fastest growing domestically in the past 10 years. one of the industries. [0003] Plant extraction mainly extracts active substances in plants. Different active substances have different effects, such as: anti-aging, anti-fatigue, anti-radiation, anti-hypoxia, anti-virus and anti-tumor, anti-peroxidation, etc., and its effect The quality of the effect is often directly related to the purity of the plant extract. The purity of plant extracts is a key indicator for identifying the quality of...
