Abstract
The invention discloses a kind of preparation technology of Chinese rhubarb extract enteric-coated micro-pill, mainly extracts Chinese herb rhubarb and concentrates, then macroreticular resin is handled.Obtained rheum officinale extraction concentrate is well mixed and dried with macroreticular resin, obtains the ball heart of enteric-coated micro-pill.This ball heart is subjected to fluidized bed coating, then row drying with acrylic resin, you can obtain Chinese rhubarb extract enteric-coated micro-pill.Chinese rhubarb extract enteric-coated micro-pill prepared by the present invention, can avoid the cold and cool injury to stomach Qi of rheum officinale, while add concentration of its active ingredient in enteron aisle.This law prepares enteric-coated micro-pill concise in technology, has very big economic value.
Description
Technical field
" a kind of preparation technology of Chinese rhubarb extract enteric-coated micro-pill " of the invention belongs to field of traditional Chinese, especially belongs to Chinese medicine
Enteric coated pellets formulation field.
Background technology
Traditional oral preparation of Chinese traditional medicinal, such as pill, powder, granule, tablet, capsule and liquid preparation, exist mostly
Disintegration in the stomach or dissolving, it is irritant to gastric mucosa, have influence on appetite of patient etc..Especially the property of medicine such as rheum officinale it is cold and cool in
Medicine, long term usage injure one's stomach gas, influence spleen and stomach function, the healthy tendency of people is come to harm.In addition, the hydrochloric acid in gastric juice also usually can be to medicine
The active ingredient of thing plays a part of destruction, the effect of so as to have influence on medicine.Enteron aisle is the main portions of drug absorption.Enteron aisle
During infection, it is especially desirable to there is sufficient concentrations of medicine or middle the effective elements of the medicine to act on focus part, both improve curative effect, subtract
Lack the generation of side effect, also reduce the dosage of medicine.Therefore, herbal nature is cold and cool and to upper digestive tract medicine excitatory
Thing, it is especially suitable for being prepared into enteric coated preparations.When particularly the lower digestive tract such as treatment diarrhoea infects, enteric coated preparations can play preferably
Curative effect.
The content of the invention
" a kind of preparation technology of Chinese rhubarb extract enteric-coated micro-pill " of the invention, it is characterised in that:Rhubarb decoction pieces are poured into 5 ~
In the boiling water of 10 times of weight, boiling 5 ~ 15 minutes is kept, is incubated filters with 200 ~ 300 eye mesh screens while hot, gained filtrate 1 is standby.
The decocting that the obtained dregs of a decoction add 5 ~ 10 times of weight is boiled twice, and boiling 30 ~ 60 minutes is kept after boiling every time, is filtered while hot,
Respectively obtain filtrate 2 and filtrate 3.Merging filtrate 1, filtrate 2 and filtrate 3, by this, 60 ~ 75 DEG C of filtrate is concentrated under reduced pressure into relatively three times
Density is 1.05 ~ 1.10 concentrate.On the other hand, macroreticular resin is added in the deionized water of 5 ~ 10 times of weight, in 50 ~ 60
DEG C heat-insulation soaking 12 ~ 24 hours, constantly stirs, changes a water within every 2 ~ 4 hours.It is big by what is drained away the water after last time changes water
Hole resin is added in 60% ~ 80% edible alcohol of 5 ~ 10 times of weight, in soaking at room temperature 2 ~ 3 times, is soaked 2 ~ 4 hours every time.
Macroreticular resin after alcohol-pickled processing is put into recovered alcohol in rotary evaporation in vacuo drier, then the big of alcohol will have been reclaimed
Hole resin is transferred in vacuum drying chamber to be dried under reduced pressure 4 ~ 8 hours in 50 ~ 80 DEG C, is crossed 40 ~ 80 mesh sieves, is removed fine powder, is obtained through place
Macroreticular resin particle after reason.The ball heart using this macroreticular resin as enteric-coated micro-pill, foregoing rheum officinale is extracted into concentrate by weight
1 ~ 3 part is taken, is sufficiently mixed uniformly by weight 7 ~ 9 parts with the macroreticular resin after aforementioned processing, 50 ~ 60 DEG C are dried under reduced pressure 8 ~ 24
Hour, obtain drug containing macroreticular resin.The ball heart using this drug containing macroreticular resin as enteric-coated micro-pill, is wrapped with fluidized bed coating and contained
The acrylic resin II of medicine macroreticular resin ball heart weight 3% ~ 10%, is drying to obtain finished product.
Rheum officinale plays the role of spectrum antibacterial, anti-inflammatory, cholagogic etc..Its property of medicine very bitter cold, orally has to spleen and stomach function
Injury, the compliance of medication are bad.The effect of rheum officinale is captured, clinically it is commonly used to treat constipation.It is micro- to be prepared into enteric
Ball, it is just disintegrated, discharged under the pH environment of enteron aisle, solve its bitter cold injure one's stomach gas the drawbacks of, reduce its bitter taste pair
The sense of discomfort of oral mucosa, meanwhile, the concentration that its active ingredient is acted on and absorbed at enteron aisle position is also improved, it is added and lets out
The effect of lower.
Embodiment
Facility example 1
Rhubarb decoction pieces are poured into the boiling water of 8 times of weight, keep boiling 10 minutes, be incubated filter with 200 eye mesh screens while hot, gained
Filtrate is standby.The decocting that the dregs of a decoction add 5 times of weight is boiled twice, and boiling 60 minutes is kept after boiling every time, is filtered while hot.Merge
Filtrate three times, it is concentrated under reduced pressure into the concentrate that relative density is 1.05.On the other hand, macroreticular resin is added into 8 times of weight
Deionized water in, in 50 DEG C of heat-insulation soakings 12 hours, constantly stir, change a water within every 2 hours.The macropore tree that will be drained away the water
Fat adds 60% edible alcohol of 5 times of weight, in soaking at room temperature 2 times, immersion 2 hours every time.Will be after alcohol-pickled processing
Macroreticular resin put in rotary evaporation in vacuo drier after recovered alcohol, be then transferred in vacuum drying chamber and be dried under reduced pressure in 50 DEG C
