Abstract
The invention relates to a preparation method and an application of pomegranate polyphenol. The method is as follows: fresh pomegranate follows are collected, washed and smashed. An organic solvent is used to extract soluble material containing pomegranate polyphenol from the smashed pomegranate flowers. Then a pomegranate polyphonol concentrated solution is obtained form polyphenol extract by enrichment through a macroporous absorption resin method. The polyphonol concentrated solution is subject to spray drying and freeze drying to obtain high-purity pomegranate polyphenol. The pomegranate polyphenol obtained by the method is more than 70 percent, with a yield rate more than 10.3/100g (pomegranate flower), has non-oxidizability, is particularly suitable for food, health care product or medicine and provides an effective way for the comprehensive application of plant pomegranate polyphenol.
Description
Technical field
The present invention relates to a kind of preparation method of granada flower polyphenol, lose weight, increase the medicinal usage of immunity, antioxidative functional food adjuvant and auxiliary treatment atherosclerosis, diabetes, hypertension and cancer by the granada flower polyphenol of this method acquisition as preparation.
Background technology
The flower of Punica granatum L. Pittosporum Punicaceae plant Punica granatum L. (punica grantum L.), alabastrum are red.Contain glucose, fructose, tannic acid (tannin) etc. in the Flos Granati.In ethnomedicine plain with the title of " Gu Li moves " people's medicine, have antidiarrheal, hemostasis, effect such as antipruritic, can be used as the drug use of treatment halitosis, bromhidrosis; Ancients usually will spend battalion's sugaring to make extractum, in order to treatment gastric ulcer and straightforward words tripe; Flos Granati removes and can be used to treat diseases such as neurasthenia, insomnia, also has the effect of building body.
Punica granatum L. polyphenol is the general name that a class has the polyphenol hydroxyl chemical compound, comprise multiple chemical compounds such as elladitannin, Galla Turcica (Galla Helepensis) tannin, ellagic acid, gallic acid, catechin, anthocyanidin, chlorogenic acid, ferulic acid, at present pharmaceutical research shows that Punica granatum L. polyphenol just has biological activitys such as antioxidation, defying age, antibiotic, antiviral, blood pressure lowering, blood fat reducing and arteriosclerosis.Therefore, aspect the treatment cardiovascular diseases DEVELOPMENT PROSPECT is widely being arranged.
Flos Granati is being bloomed to forming in alabastrum, the outcome procedure, because the influence of natural phenomenas such as wind, rain, only having 1/3 can the result, and all the other 2/3 are wasted because of landing.Therefore from Flos Granati, extract and the preparation medicinal ingredient for increasing additional value of farm products and its very big effect of comprehensive utilization ratio aspect.
At present Flos Granati is had only flavonoid and pigment aspect are had research, as patent of invention (application number: 200610045466.9) " from Flos Granati, extract the method for Flavonoid substances, ellagic acid ", disclosing a kind of is raw material with the Flos Granati, drench through dashing, dry, use methods such as deionized water heating extraction, filtration, reverse osmosis concentration, spray drying, finally obtain the method for Flavonoid substances, ellagic acid.
And preparing the granada flower polyphenol compounds, relevant employing macroporous resin do not appear in the newspapers.
