Description

A kind of processing method of the bright prepared slices of Chinese crude drugs

The present invention relates to the processing method of pure natural medical, is a kind of method that bright Chinese crude drug directly is processed into bright medicine decoction pieces specifically.

Use Chinese herbal medicine and cure the disease in the history in existing several thousand of China, the use of fresh plant medicine is more earlier at various process of preparing Chinese medicine medicines.Say in " Records of the Historian ": " shennong went into the mountains collecting, tasting and testing different kinds of herbs to be used as medicine, and there is medicine the beginning ", sidewalk have gone out the historical facts that our the civilian fresh plant medicine of elder generation is cured the disease.The fresh plant medicine to be used for clinical be a big characteristic of the traditional Chinese medical science, have the advantage that the medicine source is extensive, collection is easy to use, curative effect is safe and reliable, with low cost: the great advantage that it is believed that the fresh plant medicine just is " aquatic foods ", come compared with common decoction pieces with kind, the active ingredient of bright product does not change, the efficacy of a drug is bigger than common decoction pieces, and many special drug effects are arranged.For many infectious disease that caused by pathogenic bacteria, virus is that epidemic febrile disease, heat syndrome use bright medication effect more quick.But bright medicine also has not anti-storage, the shortcoming of inconvenience transportation.Traditional practice is that the pharmacy that is transported to various places provided use after at source (processing factory, decoction pieces factory, pharmaceutical factory, pharmacy) processing was concocted with bright medical material, and not only interim in processing, the active ingredient of medical material is run off very big through oxydrolysis; Shortcomings such as its water content of medical material after concocting still has 7-13%, in the transporting procedures, also may produce and go mouldy, and will pass through processes such as suction, swelling, infiltration, stripping when absorption is taken in decoction, and the long utilization rate of life period is low.Therefore, how keeping the active ingredient of bright medical material and be absorbed by the body effectively as early as possible, is the problem that the world of medicine pays close attention to.

Purpose of the present invention, at the shortcoming that exists in the present Chinese medicine beverage and the medical material processing process of preparing Chinese medicine, providing a kind of utilizes bright Chinese medicine medical material to be processed into the method for bright medicine decoction pieces, reach the content that keeps active ingredient in the bright medical material most effectively, and can be absorbed by the body apace, thereby can improve the utilization rate of medical material greatly.

For overcoming the shortcoming that the existing prepared slices of Chinese crude drugs exist,, make a breakthrough finally through research for many years; The processing method of bright medicine decoction pieces of the present invention is to have adopted modernized science and technology, in medical material place of production collection period, directly bright medical material being carried out the cell wall breaking of program low temperature handles, and take out the branch that anhydrates rapidly, be processed into bright medicine decoction pieces, make its water content few, and kept active ingredient in the bright medical material to greatest extent.Its concrete procedure of processing is:

(1) will cut into slices or stripping and slicing after the clean system of bright medical material, described bright medical material is meant the medicinal plants and the animal pharmaceuticals of newly gather collection period rhizome class, floral leaf class;

(2) will cut into slices or the medical material of piece is put into-10 ℃ of refrigerated cylinders of vacuum equipment, in 1 hour, reduce to-30 ℃--50 ℃, then;

(3) be heated to 20 ℃, kept 1 hour;

(4) be cooled to-60 ℃--100 ℃ again, and start the vacuum system evacuation, remained on negative pressure 100Pa-150Pa/8 hour, be processed into bright medicine decoction pieces.

By above-mentioned processing technique step, the medical material cell wall is destroyed, and under the cryogenic vacuum condition, the water ice that forms in the medical material, directly distillation is taken away rapidly, to greatest extent the moisture content in the medical material is removed, make the water content in the bright medicine decoction pieces extremely low, (table 1) and kept active ingredient in the bright medical material most; And crisp easily chew (photo 1,2), mouthfeel is better than common decoction pieces greatly.

With the bright medicine decoction pieces that the inventive method is processed into, not only lovely luster exactly likes former phytomorph, and many common decoction pieces advantage is can't be obtained arranged.As 1, the water content of bright medicine decoction pieces is 1-4% only, is significantly less than the water content of the 7-13% of ordinary tablet, so anti-accumulating is difficult for infested going mouldy.2, because bright medicine decoction pieces has been carried out the cell wall breaking processing, so decoct or when directly taking after mixing it with water, intracellular effective ingredient stripping rapidly and fully improves the medical material utilization rate greatly.And the common decoction pieces process-cycle long (usually through processing in production place, the processing of decoction pieces factory, pharmaceutical factory, pharmacy processing), adding the duration active ingredient runs off very big and takes when absorbing in decoction through oxydrolysis and will pass through processes such as suction, swelling, infiltration, stripping, not only the time long but also utilization rate is low, particularly expensive thin medicine and require the medical material of quick acting.3, because the advanced person of processing technique, so contain the bright medicine decoction pieces volatile oil content height of volatile ingredient, other effective ingredient such as flavonoid, alkaloids, glycoside, polysaccharide etc., because of processing such as the Exposure to Sunlight that does not meet with common decoction pieces processing, fiery baking, immersions, so do not have chemical changes such as oxidation, degraded, condensation, so content is higher, drug effect is stronger.4, course of processing sealing health is pollution-free, so can directly make chewable tablet; Also can decoct with other bright decoction pieces preparation.We are particularly useful for the dietotherapeutic medical material, particularly expensive thin medicine and the medical material that requires quick acting.
