Thus, the compound can be used for resisting senility and treating cardiovascular and cerebrovascular diseases, etc.
Description
Technical field
The present invention relates to a kind of new compound, particularly a kind of chestnut flower chromocor compound and extracting method thereof.This compound has to be had anti-oxidantly, removes the oxyradical effect, improves cerebral blood circulation, can be used for anti-ageing, the treatment of cardiovascular and cerebrovascular diseases etc.
Background technology
Chestnut flower is the male inflorescence of Fagaceae Castanea plant Chinese chestnut (Castanea mollissima Blume).Chestnut flower water decoction is used for the treatment of cureless diarrhoea among the people." daily book on Chinese herbal medicine " record chestnut flower tepor, little hardship, puckery.Control scrofula." the southern regions of the Yunnan Province book on Chinese herbal medicine " carries and controls with the passing of time dysentery, blood under the large intestine." Sichuan Chinese medicinal herbal " carries and controls infantile dyspepsia and suffer from diarrhoea more than.Chestnut is distributed widely in all parts of the country, and resource is very abundant, and especially cultivation is concentrated in the Shandong Province, and output is very big, and Li Huadou abandons need not.The home and abroad to colored research seldom.Up to the present, only reported the volatile oil component in the chestnut flower in the prior art, other chemical ingredientss of not appearing in the newspapers.
Summary of the invention
The object of the present invention is to provide a kind of chestnut flower chromocor compound that from chestnut flower water, extracts as effective constituent.
In addition purpose of the present invention be to provide a kind of method of from chestnut flower water, extracting the chestnut flower chromocor compound and,
In addition purpose of the present invention is to provide a kind of purposes of trembling colored chromocor compound.
In order to finish purpose of the present invention, the present invention relates to one group of chestnut flower flavones new compound shown in general formula (I): general formula (I)

The inventor has at first carried out comprehensive and systematic extraction and has separated the chemical ingredients of its chestnut flower, mainly is to use the opposed polarity solvent extraction, and multiple and column chromatography for separation repeatedly obtains several compounds.By the mensuration of physico-chemical property, the utilization of multiple spectroscopic technique, the compound that separation is obtained carries out the structure evaluation, identifies the present invention's compound again.These compounds all are to obtain by separating in this compound first.
On the basis of understanding fully its chemical ingredients and content, the flavonoid compound of its main component is carried out bioactivity screening, find resisting oxygen lack under the mouse normal pressure obviously (P＜0.01) and toxicity is less.This result of study has important academic values to the development and use chestnut flower, simultaneously also potential social benefit and economic benefit greatly.
Specifically, the preparation method of chestnut flower flavonoid flower flavone compound may further comprise the steps:
A) adopt 50-95% alcohol reflux chestnut flower meal, extract each 1 hour 3 times;
B) gained liquid is condensed into paste under 50-100 degree centigrade, and the depositing in water with 5 times of amounts of raw material falls then, and is centrifugal, gets the clarifying aqueous solution;
C) with this aqueous solution through macroporous resin adsorption, adsorption column is with the ethanol elution of 40-70%;
D) elutriant gets paste at 50-100 degree centigrade of concentrating under reduced pressure;
E) with 1-3 times of silica gel mixed sample of gained paste, dry, in apparatus,Soxhlet's, ethyl acetate extraction, extracting solution concentrates evaporate to dryness, gets the total flavones part of chestnut flower;
F) the chestnut flower total flavones that obtains with dissolve with ethanol, with 1-3 times of silica gel mixed sample of described paste, with 20 times of silica gel upper props of sample, the volume ratio of chloroform and methyl alcohol is 99: 1-80: 20 gradient elutions, detect with the silica-gel plate thin-layer chromatography, identical effluent merges;
G) the gained effluent is respectively through low pressure silicagel column purifying, at-5-20 ℃ recrystallization, The compounds of this invention.
New representative compounds of the present invention is:
Chestnut glucoside A[chemistry kaempferol 3-oxygen by name-(6 "-E-is right-coumaric acyl)-α-D--mannopyranose glycosides Castanoside A (Kaempferol-3-oxygen--(6 "-E-p-coumaroyl)-α-D-mannopyranoside) .];

Experimental example 1 chestnut flower chromocor compound is to the test of mouse resisting oxygen lack
8 every group of mouse random packet, gastric infusion, once a day, each 0.5ml/20g mouse (drug level is 20mg/ml), continuous irrigation stomach 7 days, 1.5 hours begin to do hypoxia endurance test after last administration, learn by statistics and handle, chestnut flower flavones group and control group relatively have significant differences (P＜0.01).Illustrating that the chestnut flower flavones has an effect to cardiovascular, is the cardiovascular effect of treatment of a new class type that gets a good chance of.
Experimental example 2 chestnut flower chromocor compounds are to the acute toxicity test of mouse
Because of being subjected to the influence of mouse stomach amount, can't measure, so done the test of dosis tolerata,, do not find the overt toxicity reaction to the disposable filling stomach chestnut of mouse flower total flavones 0.8ml/20g (1.6g/kg), observed 7 days, there is not death, well-grown.Anatomic observation, the main organs Non Apparent Abnormality shows that tentatively this product toxic side effect is very little.
This shows that the chestnut flower chromocor compound has phenolic hydroxyl group and unsaturated double-bond, it is anti-oxidant to indicate that it has, and removes the oxyradical effect, improve cerebral blood circulation, can be used for anti-ageingly, cardiovascular and cerebrovascular diseases is as hypertension, diseases such as coronary heart disease, and this class disease incidence height, quantity is big.Therefore this compounds has its important medical use, and its DEVELOPMENT PROSPECT is better, and potential market and considerable economic worth are arranged.
