Abstract

The invention provides an extraction method applicable to water-soluble thermal-sensitive components of traditional Chinese medicines. The extraction method includes steps: adding water at 95-100 DEGC into medicinal materials, heating to keep the temperature at 95-100 DEG C, and performing soaking extraction for 15-30min for 2-3 times. According to the extraction method, the water at 95-100 DEG Cis adopted for repeated soaking extraction of the traditional Chinese medicinal materials, and by strict control of soaking time and extraction times, loss of the thermal-sensitive components is reduced while complete extraction of effective components is guaranteed. By adoption of the boiled water, microorganisms in water and extract liquid can be eliminated, so that storage time of the extractliquid is prolonged, and the risk of disqualification in bacterium detection of finished products is reduced; in addition, dissolved matters of water-soluble impurities in the medicinal materials arereduced, the effective component content is increased, and dosis is reduced for patients.

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...
