Tradition is concocted the Radix Aconiti method: get clean Radix Aconiti size separately, water or saturated limewater are dipped to the interior no dried heart, take out to add water boil 4~6h, only get the big individual solid person of reaching and cut the interior no white heart, when mouth is tasted little living numb feeling in the tongue, take out and coolly do to sixty percent, be drying to obtain the Radix Aconiti Preparata sheet.Its detoxifcation mechanism be Aconitum carmichjaelii Debx. in the immersion and boiling process of long period, hypertoxic aconitine is hydrolyzed into toxicity less even benzoyl aconine seldom and aconine.
This tradition concocting method has following defective:
1, lime water soak and decocting in water after, with the no white heart in cutting, it is quality control standard that mouth is tasted sense organ such as little living numb feeling in the tongue, has the incomplete probability of aconitine hydrolysis, also just has the danger of poisoning;
2, because of differences such as the places of origin of raw materials, trophophase and process of preparing Chinese medicine conditions, cause the uncertain of finished product mesaconitine, aconitine content, influence drug effect;
3, the soak that is abandoned in the concocting process contains mass efficient composition aconine, is the significant wastage to raw material.
Summary of the invention
For solving the defective that exists in traditional concocting method, the invention provides a kind of preparation method of low toxicity aconitum analgesia preparation, its technical scheme of taking is:
This preparation method adopts following processing step:
1) preparation of drug extract:
1. get Radix Aconiti or Radix Aconiti Kusnezoffii, pulverize the NaOH-alcoholic solution lixiviate of back, keep water temperature, reflux or supersound extraction 6-8 hour at 80-90 ℃ with 0.1mol/L;
2. the filtering residue that obtains after filtering is used the NaOH-alcoholic solution lixiviate twice of 0.1mol/L again, keeps water temperature at 80-90 ℃, reflux or supersound extraction 6-8 hour;
3. after the filtrate that 1. 2. obtains with step by step merges, at first reclaim ethanol to there not being the alcohol flavor, transfer PH to arrive neutrality then, the gained concentrated solution is the drug extract of aconine compounds;
4. concentrated solution at first extracts with chloroform, merges to obtain organic facies, uses anhydrous magnesium sulfate drying then, after the filtration filtrate is used the Rotary Evaporators evaporate to dryness, thereby obtains the crystal of Aconitum carmichjaelii Debx. total alkaloids;
2) tablet or drop pill preparation
According to the conventional preparation method of tablet or drop pill, in crystal, add substrate and mix, tabletting or make drop pill.
Concentration of ethanol can be controlled in 10%-95% in the NaOH-alcoholic solution.
The beneficial effect that the present invention had is:
1, with the lixiviate of NaOH-alcoholic solution, 80-90 ℃ of hot reflux or supersound extraction make Aconitum carmichjaelii Debx. in the immersion and boiling process of long period, and the aconitine of severe toxicity is hydrolyzed into toxicity less even benzoyl aconine seldom and aconine;
2, take the lixiviating solution that contains mass efficient composition aconine, improved the bioavailability of medical material;
3, purification and quantitatively aconine, replacing traditional sense organ is quality control standard, improves the accuracy and the safety of dosage.
