Abstract

The invention discloses a method for preparing and partially-synthesizing chlorogenic acid from the processing residual liquid of aqua lonicerae foliae, which belongs to a method for manufacturing chemical substances or medicines and solves the problem of the existing chlorogenic acid extraction and preparation technology that a large amount of organic solvent is used and causes environmental pollution, or the production is difficult to expand as a relatively complex separation technology is used, or the extraction efficiency is low, the utilization rate of raw materials is relatively low and so on. The method comprises a deposition step, a separation step by using macroporous absorption resin, an acid hydrolysis step, a separation step by using ion exchange column, a semi-synthesis step and a crystallization step. The invention realizes comprehensive utilization of resources by adopting the processing residual liquid of aqua lonicerae foliae as a raw material, and can make full use of the caffeoylquinic acid substances during the extraction, hydrate the compounds into caffeic acid and quinic acid, then synthesize the chlorogenic acid and finally obtain chlorogenic acid with the purity over 99% through the crystallization step. The process of the invention is simple and can be easily expanded to industrial production while greatly improving the utilization rate of the raw material.

Description

technical field [0001] The invention belongs to the production method of chemical substances or medicines, and in particular relates to a method for preparing and semi-synthesizing chlorogenic acid by using honeysuckle dew processing residual liquid as a raw material. Background technique [0002] Chlorogenic acid (Chlorogenic acid), chemical name: 3-caffeoylquinic acid, is a depsipolic acid generated from caffeic acid (Caffeic acid) and quinic acid (Quinic acid, 1-hydroxyhexahydrogallic acid). A phenylpropanoid compound produced by plants through the shikimate pathway during aerobic respiration. [0003] Chlorogenic acid has pharmacological effects such as antibacterial, anti-inflammatory, detoxification, choleretic, blood pressure lowering, increasing white blood cells, significantly increasing gastrointestinal motility and promoting gastric juice secretion, and has strong inhibition on Escherichia coli, Staphylococcus aureus, pneumococcus and viruses Function: It has obv...
