Summary of the invention:
The invention provides a kind of Chinese medicinal tablet for the treatment of all cards before and after menopause and preparation method thereof, this tablet is by Radix Rehmanniae Preparata, Rhizoma Coptidis, and the Radix Paeoniae Alba, Radix Scutellariae, Colla Corii Asini, Poria is made.
The present invention is with Radix Rehmanniae Preparata, Rhizoma Coptidis, the Radix Paeoniae Alba, Radix Scutellariae, Colla Corii Asini, the Poria raw material is processed through extraction or other modes, makes pharmaceutically active substance, subsequently, with this material is raw material, adds the medicine acceptable carrier when needing, and makes according to the routine techniques of galenic pharmacy.Described active substance can obtain by extracting raw material of Chinese medicine respectively, also can obtain by the co-extracted raw material of Chinese medicine, also can obtain by other modes, as: by pulverize, squeeze, calcine, grind, sieve, percolation, extraction, water are carried, alcohol extraction, ester are carried, methods such as ketone is carried, chromatography obtain, these active substances can be the material of extractum form, can be that dry extract also can be a fluid extract, make different concentration according to the different needs decision of preparation.Since Radix Rehmanniae Preparata, Rhizoma Coptidis, the Radix Paeoniae Alba, Radix Scutellariae, the active substance that Colla Corii Asini, Poria are made has the easy moisture absorption, loose, instability, characteristics such as bitter in the mouth, therefore it is very important to select suitable medicine acceptable carrier to prepare tablet of the present invention, the present invention has selected pregelatinized Starch especially, magnesium stearate, and low-substituted hydroxypropyl cellulose is as the carrier of tablet of the present invention, it is that adjuvants such as different diluent, binding agent, lubricant and fluidizer have been carried out the result who draws after the screening, preferably comes out.The pharmaceutically active substance of tablet of the present invention is made by following Chinese medicinal raw materials,
Radix Rehmanniae Preparata 600g Rhizoma Coptidis 600g Radix Paeoniae Alba 300g
Radix Scutellariae 300g Colla Corii Asini 100g Poria 100g
Method for making is as follows:
Above Six-element, Poria, Colla Corii Asini mixed powder are broken into fine powder; Radix Scutellariae adds 100 ℃ of decoctings of 5 times of amounts and boils secondary, each 1.5 hours, filters merging filtrate; All the other Radix Rehmanniae Preparata etc. three flavor, add 5 times of water gaging soaked overnight after, decoct secondary, each, 1.5 hour, filtering, filtrate and above-mentioned filtrate merge, and are concentrated into the clear paste of relative density 1.10 (70 ℃), spray drying, the powder that gets dry extract promptly gets pharmaceutically active substance of the present invention with above-mentioned fine powder mixing.
The carrier pregelatinized Starch that pharmaceutically active substance of the present invention and the present invention select as tablet of the present invention, low-substituted hydroxypropyl cellulose, hybrid process is granulated, drying, it is an amount of to add magnesium stearate, and mixing is pressed into 1000, the bag film-coat, promptly.
Wherein pregelatinized Starch addition is 30g, and the low-substituted hydroxypropyl cellulose addition is 30g, and the magnesium stearate addition is 1.65g.Screening obtains the ratio of above weight proportion through science, is that adjuvants such as different diluent, binding agent, lubricant and fluidizer are screened, and by result of the test, preferably comes out.Its screening process is as follows:
Select for use pregelatinized Starch, low-substituted hydroxypropyl cellulose, carboxymethyl starch sodium as filler and disintegrating agent, we cooperate this extract powder to above-mentioned adjuvant, respectively with 70%, 80%, 90% alcohol granulation, tabletting, and be index with the hardness and the disintegration of particulate flowability (angle of repose-funnel method), tablet respectively, investigate the quality of prescription, the results are shown in Table 1.

Above-mentioned experimental result shows, with write out a prescription three, the tabletting effect of prescription six is preferable, but low-substituted hydroxypropyl cellulose is inexpensive than carboxymethyl starch sodium, so choosing prescription three, i.e. dried cream powder and pregelatinized Starch mixing are with 80% alcohol granulation, drying, it is big to be lower than 80% alcohol granulation viscosity, 80% above alcohol granulation be should use, low-substituted hydroxypropyl cellulose and magnesium stearate mixing added, tabletting.
The extraction process of pharmaceutically active substance of the present invention also obtains through screening, and this technology has substantive progressive than existing technology, and this technology detailed step is as follows:
1, pulverizes: get Poria, the Colla Corii Asini mixed powder is broken into fine powder, crosses in the rearmounted stainless steel cask of 80 mesh sieves standby.
2, Radix Scutellariae decocts: get Radix Scutellariae and add 100 ℃ of decoctings of 5 times of amounts and boil secondary, and each 1.5 hours,, standby with the filtration of 200 mesh sieves, merging filtrate.
3, decoction such as Radix Rehmanniae Preparata: get Radix Rehmanniae Preparata, the Radix Paeoniae Alba, Rhizoma Coptidis, add 5 times of water gaging soaked overnight after, decoct secondary, each 1.5 hours,, standby with the filtration of 200 mesh sieves, merging filtrate.
4, concentrate: get above-mentioned two extracting solution and merge, be evaporated to the clear paste of relative density 1.10 (70 ℃), standby.
5, spray drying: get above-mentioned concentrated solution, carry out spray drying by following condition, intake air temperature is 1500-170 ℃, 90-120 ℃ of air outlet temperature, and 4000 rev/mins of high speed centrifugation nebulizer rotating speeds,
Charging rate 40-60ml/ minute, powder outlet quantity 0.3-0.5kg per hour.
6, tabletting: with spray drying extract powder and Poria, donkey-hide gelatin fine powder and an amount of pregelatinized Starch, mixing, with 80% alcohol granulation, drying, granulate adds 0.3% magnesium stearate, 5% low-substituted hydroxypropyl cellulose, puts in the mixer and mixes 20 minutes.B measures the moisture of mixed powder, should be controlled at about 2.5%; The special-shaped stamping of C, control hardness>4Kg.
7, coating: a: it is an amount of to get " prompt color " HGY type gastric solubleness film coating pre-mix dose, with 85% ethanol by the preparation of 8% concentration, progressively adding in the mixer of a belt stirrer, it is stand-by to be mixed with the coating suspension.B: put into plain sheet in bag and pot, begin to rotate coating pan, rotational speed regulation is to 5-15rpm, feeds hot blast, and control tablet temperature is carried out the coating operation under 35-38 ℃ of condition, spray all coating solutions, and continuation drying 10 minutes promptly obtains the finished product behind the coating.
8, packing: be distributed into 12 of every plates with tablet packing machine.
The present invention also provides the method for quality control of tablet of the present invention, comprises, character is differentiated, checks steps such as assay.
The present invention has made tablet through technological transformation with capsule, has selected optimization formula simultaneously, has solved stability and hygroscopicity problem, has improved mouthfeel, the tablet good effect of making, and side effect is little, and taking convenience has been obtained beyond thought effect.
