Summary of the invention
The effective site that the objective of the invention is extraction blood fat reducing from the Cortex Ilicis Rotundae medical material is made Chinese medicine preparation.
The Chinese medicine preparation of blood fat reducing provided by the present invention, it is the oral formulations that a kind of adjuvant that contains the ethanol extraction of Cortex Ilicis Rotundae medical material and pharmaceutically allow is made, said extract is the dry bark with Aquifoliaceae Ilex rotunda Thunb. (Ilexrotunda Thunb.) plant, extract with the 85-95% alcoholic solution, filter, extracting solution is concentrated into 0.1-0.8 times of Cortex Ilicis Rotundae inventory, after the water that adds 2-5 times of extracting solution weight stirs evenly, the leaching precipitate, the dry extract that gets, containing Peltatin glucoside and rotundicacid total amount in the 1g extract dry product is 0.50~0.80g, and wherein Peltatin glucoside and rotundicacid mass ratio are 12~1.5:1.
The method that Cortex Ilicis Rotundae extracts with alcoholic solution, the technology of the heat reflow method of available routine or infusion process or percolation.
The convenience of taking for the patient and according to the characteristic of extract, the present invention can add the adjuvant that pharmaceutically allows with extract, process of Chinese medicine preparation is routinely made pill, tablet, capsule, as add Mel, cane sugar powder is made pill, or concentrated pill is made tablet, capsule as adding starch, dextrin etc., or adding Oleum Arachidis hypogaeae semen, gelatin, glycerol etc. are made soft capsule etc., also do not get rid of other peroral dosage form.
Beneficial effect of the present invention: 1, the extraction of active constituents of medicine, raw material is easy to get, and technology is simple, easy to operate, can put into production in enormous quantities; 2, product quality is easy to control; 3, be the Chinese medicine preparation of effective blood fat reducing, toxicity is low, and side effect is little.
Below by evidence beneficial effect of the present invention
One, the preparation of Cortex Ilicis Rotundae extract
Get Cortex Ilicis Rotundae medical material 20Kg, be ground into coarse powder, add 95% ethanol warm macerating and extract secondary, each 24 hours, filter, merge extractive liquid, is concentrated into 5.6Kg, adds 16Kg water, stir evenly, the leaching precipitate, drying gets Cortex Ilicis Rotundae extract, lot number 040408
Assay: liquid chromatography (HPLC)
Chromatographic condition and system suitability test are filler with octadecylsilane chemically bonded silica; Acetonitrile: 0.1% glacial acetic acid (50:50) is made mobile phase; The detection wavelength is 210nm.
The Peltatin glucoside reference substance is got in the preparation of reference substance solution respectively, the rotundicacid reference substance is an amount of, and accurate the title decides, and adds acetonitrile and makes the solution that every 1ml contains Peltatin glucoside 150 μ g, rotundicacid 50 μ g respectively, promptly.
Above-mentioned Cortex Ilicis Rotundae extract is got in the preparation of need testing solution, and porphyrize is got about 0.025g, accurate claims surely, puts in the 100ml measuring bottle, and it is an amount of to add acetonitrile, and at power 250W, supersound process is 10 minutes under the frequency 50KHz, puts coldly, adds dilution in acetonitrile to scale, shakes up, promptly.
Accurate respectively reference substance solution and each the 20 μ l of need testing solution of drawing of algoscopy inject chromatograph of liquid, measure, promptly.
Recording the weight content that contains Peltatin glucoside in 040408 batch of Cortex Ilicis Rotundae extract by above method is 52.59%, and the weight content of rotundicacid is 15.55%.
Two, the blood fat reducing of extract test
1 materials and methods
1.1 medicine is subjected to the reagent thing: Cortex Ilicis Rotundae extract.Lot number 040408
Positive drug: the simvastatin sheet, Shanghai Xinyi Wanxiang Pharmaceutical Co., Ltd., lot number is 071101.
1.2 instrument and reagent automatic clinical chemistry analyzer, centrifuge; 1% sodium carboxymethyl cellulose (autogamy).
1.3 the preparation of lipomul takes by weighing 15g Adeps Sus domestica and puts in the 200mL beaker, is heated to make its dissolving about 100 ℃, slowly adds the 6g cholesterol, is stirred to dissolving fully; Add 0.2g propylthiouracil and 20mL Tween 80 again, fully stir evenly.In another beaker, add the 65mL distilled water simultaneously, be placed on and be heated to 60 ℃ on the electric furnace, add the 2g cholate then No. 3, fully stir up to dissolving fully.With two kinds of solution, fully mixing is promptly made lipomul then.
1.4 60 of animal and grouping cleaning level SD rats, female, body weight 210 ± 10g is provided by Yangzhou University comparative medicine center, the quality certification number: SYXK (Soviet Union) 2002-0045.Be divided into 6 groups at random, 10 every group, that is: 1. normal control group, 2. hyperlipidemia model group, 3. simvastatin group (1.5mg/kg), 4. Cortex Ilicis Rotundae extract low dose group (150mg/kg), 5. Cortex Ilicis Rotundae extract high dose group (450mg/kg).
After 1.5 each group of experimental technique is freely absorbed the normal diet adaptability and is fed a week, model group, simvastatin group, Cortex Ilicis Rotundae extract low dose group, high dose group on this basis every morning irritate stomach by 10ml/kg amount and give lipomul, last till that experiment finishes.After one week of modeling, give corresponding medicine every afternoon: normal group and model group are given 1% sodium carboxymethyl cellulose (1ml/100g body weight), the simvastatin group is given simvastatin 1% sodium carboxymethyl cellulose suspension (1ml/100g body weight), the Cortex Ilicis Rotundae extract 1% sodium carboxymethyl cellulose suspension (1ml/100g body weight) that Cortex Ilicis Rotundae extract is low, high dose group is given variable concentrations respectively, successive administration 21 days, claimed 1 body weight in per three days, to adjust dosage.Each treated animal in administration after 21 days fasting can't help water 16h, pluck eyeball and get blood, separation of serum is measured serum total cholesterol (TC), serum triglycerides (TG), serum high-density LP cholesterol (HDL-C) and serum low-density LP cholesterol (LDL-C).
1.6 statistical disposition detects The data SPSS software and handles, enumeration data is all represented with X ± S.
2 results
Influence to hyperlipidemia model rat fat index: the results are shown in Table 1
Table 1 Cortex Ilicis Rotundae extract is to the influence of hyperlipidemia model rat fat index (X ± S)
Annotate: compare with model group,
*There were significant differences in P<0.05;
*There is highly significant difference P<0.01
Compare with normal group, there were significant differences in △ P<0.05; There is highly significant difference △ △ P<0.01
Conclusion: as can be seen from Table 1, to the rat of hyperlipemia, Cortex Ilicis Rotundae extract can significantly reduce serum total cholesterol (TC) and serum triglycerides (TG) content; Significantly reduce serum low-density LP cholesterol level (LDL-C), serum high-density LP cholesterol (HDL-C) content significantly raises.
Three, the acute toxicity test in mice of Cortex Ilicis Rotundae extract
Mouse stomach Cortex Ilicis Rotundae extract 1.25,2.5,5,10g/kg do not see in two weeks that death and other abnormal response take place, and can't measure the LD50 that is subjected to reagent thing mouse stomach.Mice is with Cmax, maximum volume, and no overt toxicity reaction does not also have dead behind interior three gastric infusions of 24h in one week.The maximum dosage-feeding that records the administration of Ilex rotunda Thunb. saponin mouse stomach is 60g/kg.
It is lower that more than the test poison that tentatively shows Cortex Ilicis Rotundae extract is paid effect.
