Problems solved by technology

[0008] Although many researchers have studied or commented on the determination methods of chlorogenic acid content, and there are many chromatographic methods used in the analysis and determination process, but all methods have their imperfections, and it is difficult to separate all chlorogenic acids and separate them. get pure
[0009] In short, there have been many reports on the extraction and purification of chlorogenic acid, but a method with low energy consumption, short time, clean process, simple method and good separation effect has not been found so far. Therefore, a new type of high-efficiency chlorogenic acid is developed Extraction and purification technology is very necessary

Embodiment 1

[0023] 1) Preparation of chlorogenic acid extract: Weigh 1-2 kg of Eucommia ulmoides, and extract it three times with pure water. Cool the feed liquid with a plate frame to below 30°C when discharging the liquid, the second time: add pure water that is 6 times the mass of Eucommia ulmoides, heat it to 60°C, and extract dynamically for 1 hour. to below 30°C, the third time: the added pure water is 8 times the mass of Eucommia ulmoides, heated to 60°C, dynamic extraction for 1 hour, discharging the liquid, and cooling it with a plate frame to below 30°C when the liquid is discharged. The liquid is used as the first extraction material liquid of the next batch;

[0024] 2) Magnetic Molecularly Imprinted Polymer: Suspension polymerization method, chlorogenic acid as template molecule, oleic acid modified nano-Fe 3 o 4 Particles are magnetic components, tetravinylpyridine is a functional monomer, carboxyethyl cellulose aqueous solution is a dispersant, and ethylene glycol dimetha...

Abstract

The invention discloses a method used for extracting chlorogenic acid from eucommia. According to the method, eucommia is taken as a raw material, and is used without drying; firstly, eucommia are water are subjected to three times of extraction to obtain a chlorogenic acid extracted solution; suspension polymerization method is adopted to obtain a magnetic molecular imprinting polymer; the prepared magnetic molecular imprinting polymer is used for adsorption of chlorogenic acid in the crude chlorogenic acid extracted solution; and condensation and pressure reduction drying are adopted to obtain chlorogenic acid. The method is low in energy consumption, high in chlorogenic acid yield, and low in hidden trouble rate, and is capable of realizing chlorogenic acid separation simply with high efficiency.

Description

technical field [0001] The invention relates to an extraction method, in particular to a method for extracting chlorogenic acid from Eucommia ulmoides. Background technique [0002] Chlorogenic acid is a phenolic compound isolated from the leaves and fruits of dicotyledonous plants (such as honeysuckle leaves, coffee beans, sunflowers, etc.), and is also used in many Chinese herbal medicines (such as Eucommia, honeysuckle, capillary, etc.) and traditional Chinese medicines. The main active ingredients of antibacterial, anti-inflammatory, heat-clearing and detoxifying compound preparations have become one of the main indicators of quality control of Chinese herbal medicine preparations. Chinese herbal medicine is the treasure of the civilization of the Chinese nation for thousands of years, and the pride of our Chinese descendants. For thousands of years, our ancestors used Chinese herbal medicines and their compound preparations to obtain extremely rich clinical experience ...
