Abstract

The invention provides an extraction method suitable for water-soluble heat-sensitive ingredients of traditional Chinese medicines. The extraction method suitable for water-soluble heat-sensitive ingredients of traditional Chinese medicines comprises the following step: adding water at the temperature of 95-100 DEG C in medicinal materials to soak and extract the medicinal materials, wherein soaking time lasts for 10-30 min, the extraction times are 3-5 times, and the environment temperature is 20-30 DEG C. In the provided extraction method, boiling water at the temperature of 95-100 DEG C isadopted to repeatedly soak and extract the traditional Chinese medicinal materials, by strictly control over the soaking time and the extraction times, it ensures that effective constituents are leached fully, and loss of the heat-sensitive ingredients is reduced. The used boiling water can further kill microorganisms in water and an extracting solution, the storage time of the extracting solutionis prolonged, the risks of unqualified bacterial inspection of finished products are reduced, meanwhile, soluble substances of water-soluble impurities in the medicinal materials are further reduced,the content of the effective constituents is increased, and the dosage of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical and chemical production, in particular to an extraction method suitable for water-soluble heat-sensitive components of traditional Chinese medicine. Background technique [0002] With the continuous advancement of science and technology, traditional Chinese medicine dosage forms are not limited to traditional soups, pills, powders, ointments, etc. New dosage forms such as traditional Chinese medicine formula granules have been accepted and used by a large number of patients. Traditional Chinese medicine formula granules, also known as decoction-free Chinese herbal pieces, new decoction pieces, refined decoction pieces, etc., refer to extracting the active ingredients in traditional Chinese medicine decoction pieces through the extraction method of traditional Chinese medicine preparations, selecting appropriate solvents and techniques, and then through concentration, drying, Made into granu...
