Description
Technical field
The present invention relates to the extracting method of plant total flavones, exactly is the extracting method of Folium Crataegi total flavones.
Background technology
Pharmacology activity research shows: the Folium Crataegi total flavones extract can reduce the blood pressure of Hypertensive Rats, and it is reduced to normal arterial pressure, to the almost not influence of blood pressure with normal arterial pressure rat; The Folium Crataegi total flavones extract has the effect of obvious reduction rat blood serum total cholesterol and triglyceride (TG) (P<0.05), and is certain dose-effect relationship; Lipid-lowering test to bait hyperlipidemia rabbit shows that the Folium Crataegi total flavones extract can significantly reduce (TC) in the hyperlipidemia rabbit anteserum (P<0.05), and simultaneously the Folium Crataegi total flavones extract has and prevents higher fatty acid disease effect preferably.The author carries out the antiplatelet aggregative activity experiment to separate 7 chromocor compounds that obtain from the Folium Crataegi total flavones extract.The result shows: the C-glycoside compound still is that the O-glycoside compound all has certain antiplatelet aggregative activity.Therefore, the Folium Crataegi total flavones extract is as a kind of physiologically active substance, uses very extensively, not only can be used as food but also can be used as the preparation raw material of multiple medicine, various healthcare products.Because the Folium Crataegi total flavones extract has high using value and prospect.So, in the last few years, comprised that the expert of many countries of China, scholar have carried out extensive and deep research to the method for extracting Fructus Crataegi total flavones from Howthorn Leaf, obtained gratifying achievements.But the most frequently used method of conclude is alcohol extract or the water extract with Howthorn Leaf to suspend in water, and uses the solvent extraction of opposed polarity successively, and solvent commonly used has chloroform, ethyl acetate and water-saturated n-butanol.Fructus Crataegi total flavones focuses mostly in n-butanol layer.The reclaim under reduced pressure propyl carbinol; Medicinal extract concentration is 95% dissolve with ethanol, and makes it pass through active carbon column; Collect effluent liquid and decompression recycling ethanol, make finished product.The subject matter of utilizing this method to produce the Fructus Crataegi total flavones existence is: (1) product cost is higher, (2) impurity in the product, particularly content of harmful is higher, wherein heavy metal content surpasses 5ppm, pesticide residue is greater than 10ppb, surpass prescribed limit, simultaneously residual toxicity solvent, n-butanol etc. inevitably also.
Summary of the invention
