Abstract
The present invention discloses a nano Gegen-celian preparation medicine. It is made up by using the Chinese medicinal materials of nano pueraria, nano scutellaria, nano coptis and nano licorice as raw material through the processes of microwave extraction, reduced pressure concentration and supersonic jet spray drying. Its grain fineness is up to 1200-1500 meshes, grain size is 0.1-200 nm, in which most of grain size is less than 100 nm. Said medicine is high in biological utilization rate and obvious in therapeutic effect.
Description
The present invention relates to a kind of expelling pathogen from the exterior and clearing up internal heat, the nanometer Gegen Qinlian preparation medicine of heat-clearing and toxic substances removing the invention still further relates to the method for this medication preparation.
GEGEN QINLIAN PIAN is a kind of Chinese patent medicine of classics, mainly contain analgesic, antibiotic, antiviral, anti-hypoxia, anti-arrhythmia, effects such as lax trachea and intestinal smooth muscle are used to have loose bowels, dysentery, fever of the body excessive thirst etc., but traditional GEGEN QINLIAN PIAN disintegrate is slower, absorb not exclusively, bioavailability is not high, slow curative effect.
The object of the present invention is to provide a kind of bioavailability height, solid dispersion is good, absorbs fully the nanometer Gegen Qinlian preparation medicine of increase evident in efficacy.
Another object of the present invention provides the preparation method of this nanometer Gegen Qinlian preparation medicine.
To achieve these goals, the present invention takes following technical scheme:
Medicine of the present invention is to make (consumption is a weight portion) by following component:

The formula optimization weight proportion scope of medicine of the present invention is:
Nanometer Radix Puerariae 10-30 part nanometer Radix Scutellariae 10-30 part nanometer coptis 10-30 part
Nanometer Radix Glycyrrhizae 3-8 part
The optimum weight proportioning of medicine of the present invention is:
20 parts of 20 parts of nanometer coptis of 15 parts of nanometer Radix Scutellariaes of nanometer Radix Puerariae
5 parts in nanometer Radix Glycyrrhizae
Technical scheme of the present invention is based on the modern material technology.One of modern material Developing Trend in Technology is to develop to the more and more littler direction of yardstick.The granule of the past composition material, its size all are at micron or more than the millimeter magnitude, and have occurred the material to the nanoscale development now.Because extremely refinement of granule, the shared percentage by volume of crystal boundary increases, and makes some performance of material that outstanding variation take place.
The property of nano material be since the particle size of the special construction----material of nano material less than the ultra-micro powder of 100nm, its body surface area is very big, the atom number ratio at crystal boundary place makes it to produce four big effects up to 15%-50%: i.e. small-size effect, quantum effect (containing macro quanta tunnel effect), skin effect and interfacial effect.Thereby has the not available physical and chemical performance of traditional material.Nanotechnology will bring a technological revolution of the field of Chinese medicines.
One of method of above-mentioned each component being made medicine of the present invention is:
1. divide and get the Chinese crude drug of respectively distinguishing the flavor of, add to concoct according to Chinese Pharmacopoeia one one of version in 2000 and be processed into the common Chinese decoction pieces
2. divide and get the common Chinese decoction pieces of respectively distinguishing the flavor of, be processed into the nanometer prepared slices of Chinese crude drugs, its method comprises the following steps:
1. the common Chinese decoction pieces is placed extraction pot, solubilizer also imports microwave extracting, makes its speed with 20-30 hundred million times/second do the change in polarity motion, and the temperature of its microwave extracting is 30 ℃-60 ℃, time 1-10 hour;
2. above-mentioned extract is carried out concentrating under reduced pressure, temperature is 30 ℃-60 ℃, and the time is 3-72 hour, collects volatile material in the Chinese medicine simultaneously in addition;
3. decompressed concentrate and volatile material merging are placed spray drying tower, use the supersonic jet technology, 330 meters-990 meter per seconds of effluxvelocity, 30 ℃ of-60 ℃ of temperature, under 0 to the 0.05MPa pressure,, promptly make the nanometer prepared slices of Chinese crude drugs with the instantaneous drying of hypersonic velocity.
3. the nanometer prepared slices of Chinese crude drugs (powder) are prepared mixing in described ratio, according to Chinese Pharmacopoeia version two-shift system in 2000 agent standard, make pill, powder, tablet, suppository, granule, membrane, capsule, microcapsule, drop pill, aerosol, injection, unguentum, medicated wine, syrup, oral solution.
Two of medicine method for making of the present invention is:
1. be equipped with whole common Chinese decoction pieces in the proportioning ratio, place extraction pot, solubilizer also imports microwave extracting, makes its speed with 20-30 hundred million times/second do the change in polarity motion, and the temperature of its microwave extracting is 30 ℃-60 ℃, time 1-10 hour;
2. above-mentioned extract is carried out concentrating under reduced pressure, temperature is 30 ℃-60 ℃, and the time is 3-72 hour, collects volatile material in the Chinese medicine simultaneously in addition;
3. decompressed concentrate and volatile material merging are placed spray drying tower, use the supersonic jet technology, 330 meters-990 meter per seconds of effluxvelocity, 30 ℃ of-60 ℃ of temperature, under 0 to the 0.05MPa pressure,, get the GEGEN QINLIAN PIAN nano powder with the instantaneous drying of hypersonic velocity jet
4. its nano powder is made aforementioned various preparation according to Chinese Pharmacopoeia version standard preparation in 2000.
The pharmacological effect that above-mentioned two kinds of methods are made nanometer Gegen Qinlian preparation medicine is identical.
A kind of important feature of the present invention is, the made drug material of the present invention has reached nanoscale, common GEGEN QINLIAN PIAN preparation material is micron or the above particle diameter of millimeter, can only cross the 80-120 mesh sieve, the drug material that the present invention is made, particle diameter is at 0.1-200nm, and the overwhelming majority can be crossed the 1200-1500 mesh sieve less than 100nm.
Another important feature of the present invention is, solid preparation of the present invention disintegrate rapidly, and solid dispersion is good in water, absorb fully, the bioavailability height, the pharmacological action effect that mainly contains effective constituent is significantly higher than conventional formulation.
The pharmaceutical preparation that the present invention is made does not need to add any adjuvant, and is more favourable to human body.
The present invention has also created the new drug formulation that powder, suppository, membrane, capsule, microcapsule, drop pill, aerosol, injection, unguentum, medicated wine, syrup, oral solution of nanometer Gegen Qinlian preparation medicine etc. is had no precedent in the past.
Pharmaceutical preparation of the present invention can be used for diarrhoea, bacillary dysentery, and amebic dysentery, enteritis, typhoid fever, superficial gastritis, treatments such as poliomyelitis, clinical efficacy significantly is better than traditional GEGEN QINLIAN PIAN.
The present invention's added solvent in microwave extracting is water or ethanol.
