Problems solved by technology

At present, most of the products containing honeysuckle are traditional Chinese medicine products with complex prescriptions. Although they have a certain curative effect, they also have disadvantages such as large dosage, slow onset of effect, inconvenient use, limited efficacy and difficult quality control.
The extraction process of honeysuckle in the prior art has a low yield of extract extracted from honeysuckle, complex process conditions, difficult control of production quality, high cost, and poor use effect

Abstract

The invention discloses a preparation method of a honeysuckle extract. The preparation method is characterized by comprising the following steps of: a, preparing, cleaning, drying and crushing a honeysuckle raw material to obtain a honeysuckle powder; b: adding water into the honeysuckle powder obtained from the step a, and then carrying out extraction and filtration to obtain a preliminary extraction solution; c, feeding the preliminary extraction solution obtained from the step b to a separation kettle for separation, collecting supernate, condensing the supernate to 20-30% of the original volume, adsorbing the condensed product using a resin column, and eluting the resin column using 60-70% of ethanol, 50-60% of ethanol and 40-50% of ethanol respectively; d, combining the eluates obtained from the step c for still standing for 1-2 hours, filtering the resulting product to obtain a crude extracting solution; and e, dying the crude extracting solution obtained from the step d to paste form to obtain a honeysuckle extract finished product. The preparation method disclosed by the invention has the following advantages that the method is greatly increased in extract yield of the honeysuckle extraction, simple in process conditions, easy in industrialization, easily controlled in production quality, low in cost and good in used effect.

Description

technical field [0001] The invention relates to a honeysuckle extract, in particular to a preparation method of the honeysuckle extract. Background technique [0002] In recent years, scholars at home and abroad have carried out comprehensive analysis and research using modern theoretical knowledge, and done a lot of pharmacological clinical work. From a scientific point of view, it has been confirmed that honeysuckle has: antibacterial, antiviral, antitumor, enhancing immunity, and detoxification. Heat anti-inflammatory, choleretic, liver protection, lipid-lowering and other pharmacological effects. Because of its special medicinal effects, it was favored by experts in the fight against SARS in 2003. Most of the Chinese medicine prescriptions recommended by the State Administration of Traditional Chinese Medicine for the prevention and treatment of SARS contained honeysuckle. It made great contributions to the fight against SARS. . At present, most of the products contain...
