Honeysuckle has the functions of clearing away heat and detoxifying, cooling and dispelling wind heat, protecting liver and gallbladder, etc. It is one of the commonly used Chinese herbal medicines. The reason why honeysuckle has the effects of detoxification and detoxification is because it contains an active ingredient, chlorogenic acid. Chlorogenic acid has anti-oxidation, antibacterial, anti-viral and anti-tumor effects. In recent years, a lot of researches have been carried out on the extraction, separation and purification of chlorogenic acid from honeysuckle. The following describes the extraction and purification of chlorogenic acid from honeysuckle by membrane separation.

 

Membrane separation technology is applicable to inorganic substances and organic substances, and has a wide range of applications, and is particularly suitable for separation of heat-sensitive substances. Most membrane separation processes do not undergo phase changes, have the advantage of no heating, low energy consumption, and no need to add any material.

 

The chlorogenic acid in the honeysuckle was extracted and purified by membrane filtration process such as microfiltration, ultrafiltration and nanofiltration. The membrane combination treatment was the best. The recovery rate of chlorogenic acid was 67.75%, and the purity of the product was 13.21%.
