Technical field
The invention belongs to field of medicaments, be specifically related to a kind of Chinese medicine Herba Cirsii effective part extract and preparation method thereof, comprise pharmaceutical composition and the purposes of this Herba Cirsii effective part extract.
Background technology
Varicosis has become the common disease of harm people's life health, weight, lack exercise, the factors such as oral contraceptive, pregnancy, climacteric, obesity, aging, heredity all can cause varicosis.Varicosis can cause the generation of hemorrhoid, and hemorrhoid are owing to causing with anal canal or subcutaneous varicosis, the expansion of anus edge under the mucosa of rectum lower end, are a kind of common diseases, and its sickness rate is about 25-40%, and more than 50 years old, old people's sickness rate is 60-70%.When patient suffers from hemorrhoid, there will be have blood in stool, the symptoms such as the hemorrhoid piece comes off, pain, pruritus, bring very large inconvenience and painful for patient's life.Varicose veins of the lower extremity is also the most common varicose vein disease, and prevalence is up to about 5-30%.Main clinical manifestation comprises that the lower limb Superficial veins expands, extends, bends to bulk; The patient has that shank is heavy, weak, swollen, the twinge of acid, feeling of numbness, edema, scratchiness, sx↑ after standing for a long time or walking; The disease later stage can occur that the scleroma of Superficial veins thrombosis forms, venous ulcer (being commonly called as " always rotten lower limb ").Affected part angiorrhexis acute hemorrhage appears in some patients were, or chronic skin ulcer is prolonged does not heal, amputation and even threat to life.
It is to cause cirsoid main cause that vein tube wall strength reduction and intravenous pressure raise, and therefore, increases the tension force of vein blood vessel, reduces intravenous pressure and just can effectively treat varicosis.
Herba Cirsii is the dry aerial parts of the perverse youngster's dish of feverfew Cirsium setosum (Willd.) MB..Its sweet in the mouth, hardship, cool in nature; GUIXIN, Liver Channel.Has cooling blood for hemostasis, the effect of removing blood stasis to reduce swelling.Its preparation blood stops immediately sheet, blood stops immediately capsule and blood stops immediately granule all for epistaxis, spits blood, and hematuria, have blood in stool, metrostaxis, the treatment of traumatic hemorrhage etc.But have no the related application and the research report that are used for the treatment of the varicosis disease about Herba Cirsii.
Summary of the invention
An object of the present invention is to provide a kind of active Herba Cirsii effective part extract with treating hemorrhage of varicosis preferably that has.
Another object of the present invention is to provide a kind of preparation method of above-mentioned Herba Cirsii effective part extract.

Again on the one hand, the invention provides described Herba Cirsii effective part extract and prevent and/or treat purposes in the medicine of varicose vein disease in preparation.
Preferably, wherein said varicose vein disease is hemorrhoid or varicose veins of the lower extremity etc.
In the Herba Cirsii effective part extract, the content assaying method of total flavones is as follows:
The mensuration of total flavones (spectrophotography)
The preparation of reference substance solution: it is appropriate that precision takes the linarin reference substance of dry constant weight, makes every 1ml with dissolve with methanol and contain the solution of 15 μ g, obtains.
The preparation of need testing solution: precision takes this product powder 50mg, puts in the 10ml measuring bottle, and adding distil water is dissolved to scale, shakes up, and filters.Precipitation connects filter paper and is placed in 100ml tool plug conical flask, adds methanol 50ml, accurately weighed weight, and supersound process 30min, weigh again, adds methanol and supply the weight of less loss, shakes up, and filters.Get subsequent filtrate 1ml, put in the 25ml measuring bottle, add methanol to scale, shake up, obtain.
The drafting of standard curve: precision measures linarin reference substance solution (0.13mg/ml) 1.0,2.0,3.0,4.0,5.0,6.0ml, puts respectively in the 25ml measuring bottle, adds methanol to scale, shakes up, and, take methanol as blank, measures absorbance at 326mn wavelength place.Take trap (A) as vertical coordinate, concentration C (μ gml
-1) be abscissa, the drawing standard curve.
Algoscopy: get need testing solution,, take methanol as blank,, according to spectrophotography (appendix VA of Chinese Pharmacopoeia version in 2005), measure trap at 326nm wavelength place.
Pharmacodynamics to medicine of the present invention has partly carried out preliminary study, found that medicine Dichlorodiphenyl Acetate of the present invention causes the rat Perianal ulceration and has obvious therapeutic action.On the basis of above-mentioned pharmacological activity test, the Herba Cirsii effective part extract is at the clinical prevention and treatment of diseases such as hemorrhoid, varicose veins of the lower extremity that can be used for.
Medicine material of the present invention source is easy to get, be easy to industrialization, can make as required various dosage forms, for clinical provide use convenient, treatment more effectively, the more controlled modern Chinese medicine of quality, for the patient brings more benefit, thereby produced huge social benefit.

Test example 1
The curative effect of medicine of the present invention is proved by following pharmacodynamics test:
1, test material
1.1 medicine and reagent
The sample of Herba Cirsii effective part extract: embodiment 1 preparation, brown ceramic powder (general flavone content is greater than 50%(weight)).The solution that is made into suitable concn with normal saline is for experiment.
Alvenor (diosmin sheet): available from Shi Weiya (Tianjin) pharmaceutical Co. Ltd.
1.2 animal
Rat: the SD rat, the male and female dual-purpose, body weight 160-180g, available from Beijing Hua Bukang biotech inc.
2, Dichlorodiphenyl Acetate causes the impact of rat Perianal ulceration
Get 50 of SD rats, male and female half and half, body weight 160-180g.Cause ulcer around anus with acetic acid: the equal and opposite in direction internal diameter filter paper that is 8mm is launched and put into glacial acetic acid fully soak, then all rats are sticked anus with the filter paper that is soaked with glacial acetic acid, filter paper need be close to anal skin and mucosa, 0.5min, and 1min changes filter paper.Divided 4 groups at random with rat, gastric infusion by body weight and ulcer level on the 2nd day.Model control group is to the equal-volume distilled water; Herba Cirsii effective part extract 200,400mg/kg group; Positive controls.In administration the 3rd, 5,7,9 days according to the rat ulcer healing state, the evaluation ulcer level.Evaluation criteria: the ulcer sepage is arranged 1 minute; A little ulcer sepage 2 minutes; There is eschar substantially to heal 3 minutes; Healed fully 4 minutes.Each treated animal white ulcer surface, crissum swelling all occur and has inflammation to ooze out after sticking 99% glacial acetic acid filter paper.
Table 1 Herba Cirsii effective part extract Dichlorodiphenyl Acetate cause the rat Perianal ulceration impact (
, n=10)
Table 1 result shows, Herba Cirsii effective part extract 200 and 400mg/kg dosage treated animal self administration of medication played Perianal ulceration on the 5th day and namely take an evident turn for the better, the healing substantially by the 9th day, the ulcer level scoring relatively has significant difference (P<0.05 or P<0.01) with model control group.
Therefore, Chinese medicine Herba Cirsii effective part extract of the present invention has therapeutic effect preferably to Perianal ulceration, suppresses significantly the edema that local inflammation causes.
