Abstract

The invention relates to the field of the medicine, in particular to a method for extracting and separating a chlorogenic acid monomer from honeysuckle. The prior art is lack of a method for the mass preparation of the chlorogenic acid monomer from the honeysuckle. In the invention, the technology is realized by the following preparation steps of: (1) soaking by alcohol: putting the honeysuckle into an alcohol solution for soaking, heating, refluxing, filtering and concentrating; (2) degreasing: degreasing the obtained filtrate thrice by adopting a weak-polarity solvent, and taking a water layer; (3) enriching by macroporous resin: enabling a water layer solution obtained in the step (2) to pass through the macroporous resin, washing by water, collecting effluent liquid and water washing liquid, concentrating and regulating the pH value; (4) extracting: extracting a solution obtained in the step (3) by adopting a moderate-polarity solvent, taking an organic layer, concentrating and recovering the solvent to obtain a faint yellow puffy solid substance; and (5) recrystallizing. The invention adopts an alcohol extraction method to enhance the extraction rate and the transfer rate of the chlorogenic acid, the final transfer rate of the chlorogenic acid is as high as 84 percent, and the purity of the obtained product can reach more than 98 percent.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a method for extracting and separating chlorogenic acid monomers from honeysuckle. The content of the chlorogenic acid monomer separated by the method reaches more than 98.0%. Background technique [0002] Honeysuckle, also known as two flowers, double flowers, golden flowers, silver flowers and honeysuckle flowers, belongs to the genus Lonicera in the Lonicera family. According to literature records: my country is one of the origins of honeysuckle, which was called honeysuckle in the "Shen Nong's Materia Medica" in the Qin and Han Dynasties more than 2,200 years ago. Li Shizhen of the Ming Dynasty gave a detailed introduction to the name, shape and characteristics of honeysuckle in his "Compendium of Materia Medica". It has a sweet taste and a cold nature. With the research of modern chemistry and pharmacology, its main active ingredients have been basically clear, but one of its main ...
