Abstract
The invention discloses a method for extracting flavone from hawthorn. The method comprises the following steps: (1) pretreating raw materials: cleaning, deseeding, cutting and pulping raw materials; (2) adding an extraction solvent: adding ethanol solution with volume percentage being 40-80% into the pulp according to a certain material-liquid ratio, and mixing; (3) carrying out water bath extraction: adding the mixed pulp liquid into a constant-temperature water bath box with the temperature being 40-60 DEG C, and carrying out extraction for 0.5-1.2 h; (4) filtering; (5) centrifuging; and (6) and carrying out rotary evaporation: carrying out concentration on the centrifuged filtrate by adopting a rotary evaporator so as to remove the solvent, and thus preparing flavone crude extract. Natural flavone substance is extracted from hawthorn, so that comprehensive utilization for hawthorn is realized, the added value of products is improved, the industry chain of hawthorn is further extended, and thus the method has broad market prospects.
Description
Technical field:
The present invention relates to a kind of extracting method of flavone, particularly relate to a kind of extracting method of Fructus Crataegi flavone.
Background technology:
Plant flavone is the polyphenol compound that a class is extensively present in plant, mainly comprises procyanidin, catechin, epicatechin, chlorogenic acid, phlorhizin, Quercetin etc.Extensively be present in veterinary antibiotics, beans cereals tea etc.The chemical property that in plant, the unique texture of flavone some row that impart it are unique its there is antitumor, antioxidation, arteriosclerosis, prevent and treat the cardiovascular and cerebrovascular disease such as coronary heart disease and apoplexy and the different physiological roles such as antibacterial.A kind of natural antioxidant and functional food ingredient.Plant flavone in the food industry, be often used as natural food additive, on purpose improve the current food production process of food quality current, apply more plant flavone in the food industry and from the blade fruit rind of the plants such as Folium Camelliae sinensis, Fructus Vitis viniferae, Fructus Kaki, Fructus Mali pumilae or marc, mainly extract the flavonoid substance plant flavone obtained mainly be used as antioxidant, antiseptic, clarifier etc. in the food industry.
Fructus Crataegi formal name used at school fruit of carambola, has another name called " carambola ", " Fructus Averrhoae Carambolae ", is Vat Jiang Cao section, belongs to tropical fruit tree, containing multiple nutritional components.Fructus Crataegi can reduce the absorption of body to fat, has the effect reducing blood fat, cholesterol, has preventive effect to the cardiovascular disease such as hypertension, arteriosclerosis.Simultaneously also can the liver protecting, reduce blood glucose.In Fructus Crataegi, saccharide, vitamin C and organic acid content are abundant, and fruit juice is abundant, can supplement rapidly the moisture of human body, promoting the production of body fluid to quench thirst, and the heat in body or alcoholism are excreted with urine, banish the feeling of languor.Containing a large amount of oxalic acid, citric acid, malic acid etc. in haw juice, the acidity of gastric juice can be improved, promote the digestion of food.Fructus Crataegi contains a large amount of volatile ingredients, carotene compounds, saccharide, organic acid and vitamin B, C etc., can eliminate laryngopharyngitis and oral ulcer, control acute toothache.Fructus Crataegi or a kind of fruit being rich in a large amount of flavone, have the different physiological roles such as antitumor, antioxidation and arteriosclerosis.There are higher nutritive value and health care.At present, have many researcheres to have studied various plant flavone both at home and abroad, as flavonoids from apple, tea flavone, Portugal's flavone, tangeritin etc., but there is not been reported about the research of Fructus Crataegi flavone.So, from Fructus Crataegi, extract natural flavone material, can fully utilize Fructus Crataegi, improve added value of product, extend Fructus Crataegi industrial chain further, there is wide market prospect.
Summary of the invention:
The object of the present invention is to provide a kind of extracting method of flavone, another object is the extracting method providing a kind of Fructus Crataegi flavone.
For this reason, the invention provides a kind of extracting method of Fructus Crataegi flavone, comprise the following steps:
1) pretreatment of raw material: Fructus Crataegi is cleaned, go seed, chopping after put into beater and pull an oar, obtain serosity;
2) add extraction solvent: by certain solid-liquid ratio add volume fraction be 40% ~ 80% alcoholic solution mix with serosity;
3) water-bath is extracted: the constant water bath box lixiviate 0.5 ~ 1.2 hour mixed serum being placed in 40 DEG C ~ 60 DEG C;
4) filter: with gauze, mixed serum is filtered, obtain filtrate;
5) centrifugal: filtrate to be placed in centrifuge tube and to put into centrifuge and carry out centrifugal;
6) rotary evaporation: the filtrate after centrifugal concentrated with Rotary Evaporators, except desolventizing, obtains flavone crude extract.
Preferably, the extracting method of described a kind of Fructus Crataegi flavone, is characterized in that, the described solid-liquid ratio added in extraction solvent can be 1: 2,1: 3 and 1: 4, and when wherein material ratio is 1: 2, Flavonoid substances extracted amount is best.
Preferably, the extracting method of described a kind of Fructus Crataegi flavone, is characterized in that, when the described volume fraction adding the alcoholic solution in extraction solvent is 60%, the content extracting flavone in haw pulp is the highest.
Preferably, the extracting method of described a kind of Fructus Crataegi flavone, is characterized in that, the optimum temperature in described water-bath extraction and event are 50 DEG C and 1.0 hours respectively.
The present invention extracts natural flavone material from Fructus Crataegi, can fully utilize Fructus Crataegi, improves added value of product, extends Fructus Crataegi industrial chain further, has wide market prospect.
