Abstract
The present invention relates to an application of a moistureproof technology in the moisture protection of traditional Chinese medicine particles. The present invention provides a production process for increasing the moistureproof property of traditional Chinese medicine particles. The present invention has the production process that a flocculation clarifying technology and a film coating technology are used singly or jointly. The production process not only can remove most hygroscopic components in a traditional Chinese medicine extracting solution in the process of flocculation clarification, but also can well reserve effective components and eliminate environmental influence caused by alcohol depositing process. The particle film coating formulation and the process conditions thereof in the production process can effectively prevent the traditional Chinese medicine particles from absorbing moisture, and can not influence the solubilization, etc. The production process well solves the moistureproof problem of the traditional Chinese medicine particles.
Description
Technical field
The present invention relates to field of traditional Chinese medicine pharmacy, particularly a kind of production technology of Chinese medicinal granule.
Background technology
In China's herbal pharmaceutical industry, to the purifying process alcohol deposition method commonly used of Chinese medicine extraction liquid.The traditional preparation process technology of Chinese medicine granules is: medical material (all crude drug or part crude drug) → concentrate extraction → early stage → precipitate with ethanol → later stage concentrates → system granule → drying → packing → finished product.For many years, it is found that the some shortcomings of alcohol precipitation process:, ethanol consumption higher as cost is big, loss also big (the ethanol waste more than 30%), finished product stability relatively poor (easily moisture absorption caking), production cycle is long, labor intensity is high, loss of effective components is serious, easily causes environmental pollution etc.For example: some polysaccharide compositions have been proved to be and have played an important role to improving immune function of human body, but in the precipitate with ethanol process, most of polysaccharide easily precipitation is removed, so be difficult to guarantee the effectiveness of preparation.
In recent years, some new materials, new technique (flocculate and clarify technology) begin to be applied to the refining to replace traditional alcohol precipitation process of Chinese medicine extraction liquid, in the hope of reducing production costs, shortening the production cycle, aspect the humidity resistance that improves product, have good effect in preparation production and lay up period especially, guarantee preparation stability and content of effective.
The kind of flocculating agent is a lot, and tannic acid, gelatin, 101 fruit juice clarifiers, ZTC clarifier, chitosan etc. are arranged.Chitosan (a kind of flocculate and clarify agent) is that the part of chitin is taken off the acetyl product, it also is the polysaccharide of unique natural alkalescence of finding so far, it is the natural high molecular substance that contains aminopolysaccharide, positively charged, but electronegative float (as cellulose, pigment, tannin, antibacterial etc.) in the sedimentation medicinal liquid.And good biocompatibility, and can be by biodegradation, the catabolite avirulence, research in field of traditional Chinese medicine pharmacy is at present used very active, the flocculate and clarify that is used for the Chinese medicine lixiviating solution, can play certain separation and purification effect, can replace the alcohol precipitation process in the Chinese medicine preparation production, reduce the pollution of environment simultaneously.
The current thin film packaging technique is used widely in tablet manufacturing technology, its main feature comprises: 1. the coating rear panel heavily increases seldom, basically reduce or without adjuvants such as Pulvis Talci (if any product adopt film coating after, not only made things convenient for the patient to take, and reduced taking dose); 2. with short production cycle, easy and simple to handle, rate of drying is fast, and medicine is subjected to damp and hotly to influence for a short time, helps improving the quality of products; 3. thin film coating material is various in style, has selectivity widely, and can utilize the different coating prescription of design, the dosage form of formation can be dissolved or disintegrate in certain pH value scope, also can be by the permeability of controlling diaphragm, reach regularly, locate the release medicine, medicine is more effectively played a role; 4. since the thin film that film coating forms at 20～40 μ m, therefore, medicine can keep former making shape, originally also can be unaffected at the labelling of dosage surface.
The factor that influences the thin film coating material humidity resistance comprises that the prescription of coating material is formed and two aspects of preparation technology of material.Scientific and reasonable preparation technology is the assurance that material property is demonstrated fully, as the stable and uniform and true reproduction of material color.In the preparation process of thin film coating material, abundant, suitable dispersion is crucial how to guarantee each component.Coating material is a compound prescription, insoluble granule is wherein arranged, these insoluble uniform particles are distributed in the colloid solution, form a stable suspension, and don't influence the melting of granular preparation, all be prescription and film-coated technique concrete arts demand consideration.In addition, how by the continuous film of spraying, exsiccant process forms one deck even compact, also be the key factor that has influence on the final moisture-proof role of product.
At present, the application that in the Chinese medicinal granule protection against the tide, also do not obtain of film-coated technique.
Summary of the invention
First purpose of the present invention provides the production technology of higher the improved Chinese medicinal granule humidity resistance of a kind of active constituent content, second purpose of the present invention provides the production technology of the stronger Chinese medicinal granule of higher, the moistureproof ability of a kind of active constituent content, and the 3rd purpose of the present invention provides the production technology of the stronger Chinese medicinal granule of a kind of moistureproof ability.
