Summary of the invention: the present invention proposes a kind of preparation method and method of inspection thereof of Folium Callicarpae Formosanae extract, with behind broken section of the Chinese medicine Folium Callicarpae Formosanae (Folium Callicarpae Formosanae), decoct with water three times, collecting decoction filters, and filtrate is concentrated into the thick paste shape, dry, obtain thick water extract dry powder, what dry powder added 95% ethanol and suitable quantity of water is adjusted to ethanol content between the 30%-95%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly; Method with percolation or reflux is extracted 2 times, filters, and precipitation is abandoned it, merges ethanol liquid, reclaims ethanol to the thick paste shape, and this step has been removed the impurity except that flavonoid, phenols; Resulting thick paste shape Folium Callicarpae Formosanae ethanol extract adds 3-8 and doubly measures 95% dissolve with ethanol; With 0.2% charcoal treatment once, this step will be removed through the pigment impurity partly that extraction is brought into again; Reclaim ethanol at last, be drying to obtain under the dry heat condition below 60 ℃.
With the Folium Callicarpae Formosanae extract that method of the present invention is extracted, it is hemorrhage to control the intestines and stomach; The spitting of blood that various diseases causes, hematemesis, epistaxis, gingival hemorrhage, hematuria, have blood in stool, dysfunctional uterine hemorrhage, traumatic hemorrhage, acute conjunctivitis, and various surgical wound surface oozings of blood etc.
The specific embodiment:
1, with behind broken section of the Folium Callicarpae Formosanae (Herb), decoct with water three times, collecting decoction filters, and filtrate is concentrated into the thick paste shape, dry, obtain thick water extract dry powder, resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 30%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 40%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 50%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 60%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 70%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 80%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol and an amount of water, and to be adjusted to ethanol content be 90%, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly, perhaps,
Resulting Folium Callicarpae Formosanae dry powder adds 95% ethanol, and make total amount be Folium Callicarpae Formosanae dry powder amount 3-8 doubly.
2, extract 2 times with the method for percolation or reflux, filter, precipitation is abandoned it, merges ethanol liquid, reclaims ethanol to the thick paste shape.
3, resulting Folium Callicarpae Formosanae ethanol extract adding 3-8 doubly measures 95% dissolve with ethanol, reclaims ethanol.
4, the exsiccant condition of thick paste: xeothermic drying below 60 ℃.
A kind of method of inspection of Folium Callicarpae Formosanae extract, step is as follows:
[discriminating]
(1) get this product 2g, add water 20ml, reflux 30 minutes filters, and gets filtrate 2ml, adds 2~3 of ferric chloride test solutions, promptly shows blackish green; Other gets filtrate 2ml, adds 2~3 of 1% gelatin solutions and promptly takes place muddy.
(2) get this product 2g, add water 20ml, reflux 1 hour filters, and filtrate is concentrated into dried, adds methanol 2ml dissolving, filters, as need testing solution.Other gets Folium Callicarpae Formosanae control medicinal material 1g, shines medical material solution in pairs with legal system.Draw each 10 μ l of above-mentioned two kinds of solution, put on same filter paper respectively, put under the ultra-violet lamp (365nm) and observe, show the fluorescence speckle of same color.
(3) get [discriminating] (2) item remaining need testing solution down, add 5% sodium nitrite solution and 10% aluminum nitrate solution each 3 and 4% sodium hydroxide solution 1ml, promptly show red.
Add medicinal adjuvant with the Folium Callicarpae Formosanae ethanol extraction, make tablet, electuary, capsule, injection, aerosol, nasal drop, suppository, external preparation and cosmetics, or daily chemical product such as toothpaste, collutory or the like, after packing, check, put in storage or dispatch from the factory.
