Embodiment Construction

[0008] The process for the adsorption and extraction of high content of chlorogenic acid by macroporous resin consists of the crushing of raw materials of honeysuckle, the extraction process of water extract containing chlorogenic acid, and the separation process of adsorption of high content of chlorogenic acid by macroporous resin; The raw material crushing process of honeysuckle is to pulverize the honeysuckle into honeysuckle particles with a particle size of less than 4mm with a sieve grinder with an aperture of 4mm; the extraction process of the water extract containing chlorogenic acid is as follows: decoct the honeysuckle particles with water for three times. The weight ratio of honeysuckle to water for the first time is 1:5, decocted for 2 hours, and the liquid is taken; the weight ratio of the second time and the third time of water decocted is 1:3, respectively, decocted for 30 minutes, and decocted for three times. The boiled medicinal solution is combined, the superna...

Abstract

A chlorogenic acid extraction process of the present invention includes crushing honeysuckle, water extraction of chlorogenic acid and macroporous resin adsorption to separate high content chlorogenic acid. It features that in the last technological step, the chlorogenic acid extracting liquid is saturated and adsorbed with macroporous resin, the chlorogenic acid in resin is washed and dissolved with low concentration alcohol to obtain chlorogenic acid eluting liquid, the eluting liquid is concentrated while recovering alcohol and the concentrated chlorogenic acid condensate is spray-dried to obtain chlorogenic acid powder product with chlorogenic acid content over 40%. The isochlorogenic acid in the resin column is produced into powder product through methanol washing and dissolving, concentrating and spray drying, after recovering method.

Description

Technical field [0001] The invention relates to a process method for extracting chlorogenic acid from honeysuckle, in particular to a process method for extracting chlorogenic acid with high content at low cost. Background technique [0002] Chlorogenic acid is the main effective ingredient with antibacterial effect in honeysuckle. Its structure is a lipid formed by combining a molecule of caffeic acid and a molecule of quinic acid. Its shape is needle-like crystals, showing strong acidity, soluble in hydrophilic solvents such as water, methanol, ethanol, etc. It contains lipid bonds in its molecular structure and is easily hydrolyzed in an alkaline environment. The extraction and separation of chlorogenic acid takes advantage of the relatively high polarity of chlorogenic acid. At present, industrial production usually adopts boiling extraction method, boiling alcohol precipitation method, 70% ethanol reflux extraction method, and water extraction lime precipitation method to ex...
