Summary of the invention
The object of the invention is to provide a kind of treatment diarrheal Herba Moslae extract preparation.
The object of the invention also is to provide the method for quality control of Herba Moslae and extract thereof.
The object of the invention also is to provide the new pharmaceutical use of Herba Moslae and extract thereof.
The present invention seeks to be achieved through the following technical solutions:
The preparation of Herba Moslae volatile oil: the Herba Moslae herb, cutting adds 6-10 times of water gaging, and vapor distillation extracted 4-8 hour, isolated the volatilization oil reservoir, promptly.
Pharmaceutical preparation of the present invention contains the Herba Moslae volatile oil of 1%-99% and the excipient of 99%-1% (medicine that comprises other adapted), preferably contain the Herba Moslae volatile oil of 30%-80% and the pharmaceutical excipient of 70%-20% (comprising the medicine that other compatibility is used), preferably contain the Herba Moslae volatile oil of 60%-70% and the excipient of 40%-30% (comprising the medicine that other compatibility is used).
Press practice of pharmacy, Herba Moslae volatile oil of the present invention can be prepared into the various clinical pharmaceutical dosage form, comprise the dosage form of oral formulations or parenterai administration.Said oral formulations is selected from any in tablet, capsule, pill, granule, suspensoid, drop pill, the oral liquid; Said parenterai administration dosage form is selected from a kind of in the middle of injection, aerosol, suppository or the subcutaneous administration dosage form.
Adjuvant in the medicine of the present invention is meant conventional excipient, as solvent, disintegrating agent, correctives, antiseptic, coloring agent, binding agent etc.The medicine that other compatibility in the medicine of the present invention is used, the MOLA oil that refers to effective dose is certain medicine material, again compatibility other allowed the Chinese medicine or the chemical drugs that share.
Above-mentioned volatile oil (MOLA oil) is yellowish supernatant liquid; Special aroma is arranged, acrid in the mouth; Store with the passing of time, color deepens slightly.
Contain following discriminating and/or content assaying method in the method for quality control of MOLA oil:
Differentiate: by the MOLA oil content assaying method, high-efficient liquid phase chromatogram has corresponding absworption peak in the retention time identical with the carvacrol reference substance with thymol.
Assay: measure according to high performance liquid chromatography (2000 editions appendix VID of Chinese Pharmacopoeia).
Chromatographic condition and system suitability test are filler with octadecylsilane chemically bonded silica; 50-70: 50-30: 1-3 methanol-water-glacial acetic acid is a mobile phase; The detection wavelength is 276nm.Number of theoretical plate calculates by the thymol peak should be not less than 10000, calculates by the carvacrol peak and should be not less than 15000.The preparation of reference substance solution, precision take by weighing thymol reference substance 8mg and thymol reference substance 4mg, put in the 100ml measuring bottle, add methanol to scale, shake up, and, contain thymol 80 μ g among every ml that is, contain carvacrol 40 μ g.The about 0.017g of this product is got in the preparation of need testing solution, and accurate the title decides, and puts in the 10ml measuring bottle, adds methanol to scale, shakes up, and precision is measured 0.9ml, to the 10ml measuring bottle, adds methanol and is diluted to scale, shakes up, promptly.Algoscopy, accurate respectively reference substance solution and each 20 μ l of need testing solution of drawing inject chromatograph of liquid, measure, promptly.This product contains carvacrol (C

14O) and thymol (C
10H
14O) total amount must not be less than 0.80%.
The pharmacodynamic study result of Herba Moslae of the present invention and volatile oil thereof shows that MOLA oil has following function:
1. the antivirus action of MOLA oil: 12.5~25nl/ml MOLA oil can suppress children's's rotavirus RDTA-I type (Wa strain) growth and breeding on African green monkey kidney cell.
2. the antibacterium of MOLA oil effect: MOLA oil can reduce Salmonella enteritidis abdominal cavity infection mortality of mice (P<0.05); Can reduce the content (P<0.05~0.01) of pathogenic bacterium in the mice stool of Salmonella enteritidis peroral infection; External, to common pathogens such as Escherichia coli, Shiga bacillus, proteus vulgaris, staphylococcus aureus, staphylococcus epidermidiss, stronger inhibition growth effect is arranged, and test is with in the 44 strain bacterial strains, and minimum inhibitory concentration≤1ul oil/ml accounts for 79.5%.
3. the anti-diarrhea effect of MOLA oil: loose stool rate, diarrhea rate, diarrhoea index and the diarrhoea degree (P<0.05~0.001) that reduce the diarrhoea model mice due to the 100% Folium Sennae decoct significantly.
4. MOLA oil is to the influence of gastrointestinal function: this medicine can reduce hyperfunction mouse small intestine propulsion functions (P<0.05~0.001) due to normal and the neostigmine, prolong defecation time, reduce defecation quantity (P<0.05~0.001), slow down gastric emptying motion (P<0.01~0.001), intestinal smooth muscle excitement due to the reduction stomachial secretion function (P<0.001), stripped intestinal smooth muscle spontaneous vasomotion of inhibition normal guinea pig and acetylcholine.
5. the analgesic effect of MOLA oil: MOLA oil reduces very significantly by the mouse writhing number due to 0.7% acetic acid (all P<0.001), and suppression ratio reaches 51.3~55.7%.
6. the antiinflammatory action of MOLA oil: MOLA oil suppresses significantly by dimethylbenzene induced mice ear swelling (P<0.01~0.001), suppress the vascular permeability (P<0.05~0.001) that histamine causes significantly, suppress abdominal cavity leukoplania (P<0.05~0.001) due to the sodium carboxymethyl cellulose.
7. the antipyretic effect of MOLA oil: MOLA oil saccharomycetic rat temperature is raise and endotoxin due to the rabbit body temperature rising inhibitory action (P<0.05~0.001) is significantly all arranged.
Following experimental example is used to further specify the present invention.
Experimental example:MOLA oil suppresses the effect of children's's rotavirus ROTA-I type (Wa strain)
Materials and methods:

6. test method:
(1) MOLA oil, GEGEN QINLIAN DIWAN and tween 80 are to the toxic action of Vero cell: will dilute good medicine, tween 80 inserts and grows up in the test tube of cell monolayer, puts 37 ℃ of incubators and cultivates, every day, observation of cell changed.
(2) medicine is to the direct killing effect of virus: put 37 ℃ of incubators 1 hour after will diluting good medicine and viral mixed in equal amounts.Access grows up in the test tube of cell monolayer then, and every pipe 0.2ml is put 37 ℃ of absorption 1 hour.Keep liquid 1ml with keeping to add after liquid is washed twice.Put 37 ℃ of incubators and cultivate, observation of cell pathological changes every day (CPE), when virus control occurs ++ ++ the time, termination test.
(3) medicine inhibitory action that virus is bred in cell: the virus that will handle inserts in the cell pipe, every pipe 0.1ml is put 37 ℃ of absorption 1 hour, with keep liquid wash after twice add respectively contain different pharmaceutical concentration keep liquid 1ml, put 37 ℃ of cultivations, every day the observation of cell pathological changes, when the virus control pipe occurs ++ ++ the time, termination test.
Annotate: cytopathy :+25%, ++ 50%, +++75%, ++ ++ 100%.
More than medicine contrast, virus control, cell contrast are established in test simultaneously, and every test group 4 solencytes repeat to do experiment twice.
The result:
1. MOLA oil the results are shown in Table 1 to the toxicity test of Vero cell.
Table 1 MOLA oil is to the toxicity test result of Vero cell
