Abstract
The invention relates to a preparation method of a high content extract of naked oat fruit flavone. In the method, a reflux extraction method of a water-containing alcohol-soluble medium is adopted to extract flavonoid compound from naked oat fruit seedlings, and then the macroporous resin absorption method is adopted to enrich the flavonoid compound in the extracting liquid, and the extract is eluted by ethanol solution, condensed and dried, and finally the extract of naked oat fruit flavone containing 20 to 45 percent of total flavone is prepared. The extract has the functions of fatigue resistance and anoxia resistance, and can be used for preparing healthcare products with fatigue resistance and anoxia resistance.
Description
Technical field
The present invention relates to the preparation method of highland barley flavone extract, relate in particular to a kind of preparation method of high-assay highland barley flavones and the application in health product thereof.
Background technology
Live in the high altitude localities or to highland tour's people, the distinct issues the most that run into be exactly be easy to generate fatigue and because of high originality anoxia brought uncomfortable, because under very abominable environment of low oxygen plateau condition, bigger change takes place in the normal physiological metabolism of human body, therefore body immunity descends, a series of body anoxia symptoms such as headache, dizzy, weak, insomnia occur, had a strong impact on people's work efficiency and healthy.
Semen avenae nudae (Hordeum vulgare L.var.nudum Hook.f.) is a kind of cereal crop of grass family Hordeum (Hordeumvulgare), and because of coetonium shell in it separates, seed is exposed, so claim hull-less barley, Mi Damai, Semen avenae nudae again.Semen avenae nudae has long cultivation history in the Qinghai-Tibet Platean, apart from modern existing 3500, mainly be distributed in the Qinghai-Tibet extremely frigid zones of 4200～4500 meters of ground height above sea level such as Tibet, Qinghai, Ganzi, Sichuan Province and Aba Tibetan Autonomous Prefecture, Tibetan Autonomous Prefecture of Gannan, Gansu Province and Yunnan, Guizhou, being the primary raw material of Zanba first of four treasured of Tibet, also is the symbol of Qinghai-Tibet agricultural Culture simultaneously.
Semen avenae nudae has abundant nutritive value and outstanding medicines and health protection effect.Put down in writing according to supplement to the Herbal: Semen avenae nudae, therapeutic method to keep the adverse QI flowing downwards alleviating distention in middle-JIAO, strong lean power, dehumidifying diaphoresis, antidiarrheal.Tibetan medicine's ancient books and records " brilliant pearl book on Chinese herbal medicine " more Semen avenae nudae as a kind of important drugs, be used for the treatment of multiple disease.
In recent years, the developmental research of Semen avenae nudae mainly concentrated on the functional component beta glucan aspect in the seed, and the active component developmental research of flavonoid is less relatively in the relevant Semen avenae nudae seedling.According to statistics, the research paper of delivering both at home and abroad about highland barley flavone class material mainly concentrates on the pharmacodynamic studies such as mensuration, qualitative and quantitative analysis and removing free radical of its chemical constitution, and result of study shows, the Flavonoid substances (main component is lutonarin Lutonarin and ZAOCAO xanthosine Saponarin) that contains high activity, structure uniqueness in the Semen avenae nudae seedling, the resisting fatigue of extractive of general flavone and anoxia enduring efficacy effect are obvious, but relevant its production technology, high-load flavone health promoting product and preparation process thereof there is no report.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method of high-assay highland barley flavones of high-load flavone.
Another technical problem to be solved by this invention provides the application of a kind of high-assay highland barley flavones in health product.
For addressing the above problem, a kind of high-assay highland barley flavones of the present invention is characterized in that: content of total flavone is 20%～45% in the described extract; Effective ingredient lutonarin content is 12%～25%, and ZAOCAO xanthosine content is 8%～20%.
The chemical constitution of described lutonarin is as follows:
The chemical structural formula of described ZAOCAO xanthosine is as follows:
A kind of preparation method of aforesaid high-assay highland barley flavones may further comprise the steps:
(1) Semen avenae nudae seedling dry, after pulverizing is added aquiferous ethanol solution with conventional reflux, extract, method extract extracting solution, reclaim ethanol in the extracting solution to determining alcohol＜below 10%, filter, get filtrate;
(2) adsorption column of filtrate flow through being filled with adsorbing material adsorbs;
(3) extremely colourless with the water wash adsorption column;
(4) with the alcoholic solution eluting of concentration 20%～60%, collect eluent;
(5) concentrate the recovery eluent, get thick paste;
(6) with the Ethanol Treatment of concentration 80%～95%, separate out precipitate, be drying to obtain extract.
Reflux, extract, condition in the described step (1) is: 70～100 ℃ of temperature, feed liquid weight ratio are 1:40～1:80, concentration of alcohol 20%～50%.
Adsorbing material in the described step (2) is a macroporous adsorbent resin.
Eluent concentration of alcohol in the described step (4) is 20%～60%.
The application of a kind of aforesaid high-assay highland barley flavones in health product is characterized in that: highland barley flavone extract is pulverized, added conventional pharmaceutic adjuvant behind 200～400 mesh sieves excessively, mix, be processed into oral formulations.
Described oral formulations is tablet, hard capsule, soft capsule, granule or oral liquid.
The present invention compared with prior art has the following advantages:
1, adopt the character of the highland barley flavone extract that the inventive method makes to be yellow powder, peat-reek is arranged, the total flavones amount reaches 20%～45%, and wherein the effective ingredient lutonarin reaches 12%～25%, and the ZAOCAO xanthosine reaches 8%～20%.
