Abstract
A process for preparing micron-class extract of Chinese emdicinal materials includes such steps as descriminating, washing, cutting, processing, drying, extracting active component, and pulverizing to obtain superfine powder less than 75 microns. Its advantages include high utilization rate of active component, high curative effect and wide application range.
Description
The present invention relates to the Chinese crude drug preparation method of extract, more specifically relate to Chinese crude drug micron preparation method of extract.
Chinese medicine and Chinese medicine preparation thereof are traditional rarities of the Chinese nation, for the prosperity of the Chinese nation has been made indelible contribution.Chinese crude drug is as the raw material of Chinese medicine and Chinese medicine preparation and the carrier of its effective ingredient, and therefore, how making full use of effective ingredient in the Chinese crude drug just becomes the basis that Chinese medicine and Chinese medicine preparation guarantee its curative effect and quality.Prior art adopts following method to the processing of Chinese crude drug is general, at first carries out Chinese crude drug and identifies, cleans then, cutting, the process of preparing Chinese medicine and drying, and this just becomes the raw material of Chinese medicine and Chinese medicine preparation.This extensive processing mode of Chinese crude drug has continued several thousand, and its shortcoming is that the effective ingredient availability of Chinese crude drug is low, and drug effect is difficult to give full play to, and the processing added value is low, has wasted a large amount of living resources, especially some rare living resources.
The purpose of this invention is to provide a kind of Chinese crude drug micron preparation method of extract, make granularity less than 75 microns medicinal substances extract, thereby make the most cells breaking cellular wall, allow the effective substance of Chinese crude drug extract be utilized, bring into play drug effect better, make full use of limited living resources.
In order to achieve the above object, preparation method of the present invention follows these steps to order and carries out:
1, choose Chinese crude drug, by traditional method identify, clean, cutting, the process of preparing Chinese medicine, drying.
2, will put into 4～10 times water or ethanol through the Chinese crude drug that said method is handled.
3, adopt infusion process, percolation, circumfluence method or extraction to extract the active substance of Chinese crude drug.
4, add suitable solvent such as entry or ethanol and carry out superfine grinding, cover with comminution by gas stream, ball mill pulverizing, vibrant pulverization, thunder pulverize, stir pulverize, one of them breaking method or the wherein combination of two kinds of breaking methods of centrifugal pulverizing, the Chinese crude drug extract is made granularity less than 75 microns micropowder.And granularity will make cell wall breaking less than 75 microns, and Chinese crude drug micron extract just is meant that granularity is less than 75 microns Chinese crude drug extract micropowder.
5, drying.
The present invention compared with prior art has following advantage:
1, because the granularity of micron Chinese medicine material extract can make the most cells breaking cellular wall less than 75 microns, therefore, it can improve the availability of Chinese crude drug extract effective substance.
2, the diffusion rate of release owing to solid drugs is directly proportional with its area, and Chinese crude drug micron extract granularity is significantly smaller than existing Chinese crude drug, thereby has increased its surface area greatly, therefore, it is more convenient and rapid in the intravital transmission of people, can improve clinical therapeutic efficacy effectively.
3, because the raising of Chinese crude drug extract effective substance availability reaches better clinical therapeutic efficacy, limited Chinese material medicine resource is utilized better.
4, the advantages of the medical treatment that Chinese crude drug itself is had and health care and micropowder, as raw material, can be made into the instant Chinese medicine of micron, micron decoction Chinese medicine, micron Chinese medicine preparation, integration of edible and medicinal herbs functional food, integration of edible and medicinal herbs pollution-free food, health food etc. with Chinese crude drug micron extract.
5, because Chinese crude drug micron extract has above advantage, can improve the surcharge of Chinese crude drug greatly, make commensurability Chinese material medicine resource obtain better economic benefit.
Fig. 1 is a micron Chinese medicine material preparation method of extract block diagram.
According to accompanying drawing preparation method of the present invention is further described below.
Preparation method of the present invention follows these steps to order and carries out:
1, choose Chinese crude drug, by traditional method identify, clean, cutting, the process of preparing Chinese medicine, drying.
2, will put into the water or the ethanol of 4～10 times of its weight through the Chinese crude drug that said method is handled.
3, adopt infusion process, percolation, circumfluence method or extraction to extract the effective substance of Chinese crude drug.
4, add suitable solvent such as entry or ethanol and carry out superfine grinding, cover with comminution by gas stream, ball mill pulverizing, vibrant pulverization, thunder pulverize, stir pulverize, one of them breaking method or the wherein combination of two kinds of breaking methods of centrifugal pulverizing, the Chinese crude drug extract is made granularity less than 75 microns micropowder.Chinese crude drug micron extract just is meant the micropowder of granularity less than 75 microns Chinese crude drug extract.
5, drying.
