Abstract
The nano stringy stonecrop medicine is prepared with nano stringy stonecrop as raw material. The new medicine preparation has a grain fineness of 1200-1500 mesh, grain size of 0.1-200 nm, mostly below 100 nm, and new physical property. It is prepared through microwave extraction, decompressing concentration, spray drying in supersonic jet and other steps. it has high biological utilization and obvious treating effect.
Description
The present invention relates to a kind of eliminating damp-heat, cure mainly the nano stringy stonecrop medicine of hepatitis, the invention still further relates to the method for this medication preparation.
Herba Sedi granule is a kind of classical Chinese patent medicine, mainly contains eliminating damp-heat, effects such as reducing glutamate pyruvate transaminase is arranged, and is used for acute hepatitis, animal migration hepatitis and chronic hepatitis of active stage.But traditional Herba Sedi granule absorbs not exclusively, and 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 nano stringy stonecrop medicine of increase evident in efficacy.
Another object of the present invention provides the preparation method of this nano stringy stonecrop medicine.
To achieve these goals, the present invention takes following technical scheme:
The weight of medicine of the present invention is:
100 parts of the bright Herba Sedis of nanometer
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 special construction----the material grains size 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, be processed into the common Chinese decoction pieces according to process of preparing Chinese medicine of Chinese Pharmacopoeia version in 2000.
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 ℃--and 60 ℃, time 1-10 hour;
2. above-mentioned extract is carried out concentrating under reduced pressure, temperature is 30 ℃--60 ℃, 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 of effluxvelocities--990 meter per seconds, at 30 ℃--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 ℃, 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 of effluxvelocities--990 meter per seconds, at 30 ℃--60 ℃ of temperature, under 0 to the 0.05MPa pressure,, get the stringy stonecrop 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 nano stringy stonecrop 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 Herba Sedi granule 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, 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 pill, powder, tablet, suppository, membrane, capsule, microcapsule, drop pill, aerosol, injection, unguentum, medicated wine, syrup, oral solution of nano stringy stonecrop medicine etc. had no precedent in the past.
Pharmaceutical preparation of the present invention can be used for treatment of conditions such as acute hepatitis, animal migration hepatitis and chronic hepatitis of active stage, and clinical efficacy significantly is better than traditional Herba Sedi granule.
The present invention's added solvent in microwave extracting is water or ethanol.
The present invention carries out in the concentrating under reduced pressure step at extract, and its concentrating under reduced pressure is conventional scheme.
