Problems solved by technology

The hydrogen bonds formed between these traditional functional monomers and chlorogenic acid molecules are very weak, and are mainly used in the research of molecularly imprinted separation columns in liquid chromatography and the research of electrochemical sensors, with weak adsorption capacity and low adsorption capacity. It is difficult to apply to the separation and enrichment of chlorogenic acid in complex systems

Abstract

The invention discloses a preparation method of a chlorogenic acid adsorption material. The preparation method comprises the following steps: firstly, adding a pore-foaming agent into a reactor; secondly, sequentially adding a template molecule, a functional monomer, a crosslinking agent and an initiator and reacting to obtain a hard solid; grinding the hard solid into powder, and carrying out soxhlet extraction and vacuum drying. The chlorogenic acid adsorption material prepared by the application has the advantages of high selectivity, high adsorption rate and high adsorption capacity on chlorogenic acid, capability of being applied to adsorption, separation and purification of the chlorogenic acid in a complex system and broad application prospect in the enrichment, separation and purification of the chlorogenic acid; the preparation method has the advantages of simplicity, easiness in operation and lower cost.

Description

technical field [0001] The invention belongs to the field of chemical organic polymer materials, and in particular relates to a preparation method of a chlorogenic acid adsorption material. Background technique [0002] Chlorogenic acid is an important biologically active substance extracted from medicinal materials such as honeysuckle and mountain silver. Modern pharmacological studies have shown that chlorogenic acid has a wide range of pharmacological activities, such as antibacterial, anti-inflammatory, antiviral, antitumor, liver protection and choleretic, increasing the number of white blood cells, lowering blood pressure, lowering blood lipids, scavenging free radicals, stimulating the central nervous system and Enhance immunity, etc. Chlorogenic acid is often used as an active ingredient in various Chinese patent medicines, natural antioxidants, feed additives, etc. It has great application value and market demand, and high-purity chlorogenic acid is expensive and i...
