Description
Technical field
The present invention relates to pharmacy and field of health care food, be specially a kind of Folium camelliae assamicae (processed) extract and preparation method thereof and its application in preparation treatment Altace Ramipril or health food.
Background technology
Yunnan puer tea is with its long history, and the charm of rich culture and glycol is world known.Folium camelliae assamicae original producton location is mainly in Simao Diqu and Xishuangbanna in Yunnan.Along with the popularization of large leaf, Sichuan, Guangdong, Guangxi also become the province that Folium camelliae assamicae is produced.In the last few years, along with expanding economy, people's health care consciousness strengthens, health preserving, health care become the theme of ordinary people daily life, Folium camelliae assamicae is with its unique health-care effect, attracted various circles of society, the scholar's of each side extensive concern especially, has among the peoplely risen especially one thereupon and has bought the upsurge in ,Yin Pu'er, ,Zang Pu'er, Pu'er.
By processing technique and qualitative characteristics, Folium camelliae assamicae is divided into two kinds of the raw tea of Folium camelliae assamicae and the ripe tea of Folium camelliae assamicae.Raw tea shines Folium Camelliae sinensis by large leaf to be made through techniques such as tidewater, steam pressure molding, and Appearance color is blackish green, dense time of greenish-yellow limpid, the flavour of soup color is sweet, leaf base fertilizer is thick yellowish green.Ripe tea needs through after fermentation technique in the course of processing, its Appearance color is reddish brown, red dense bright, the flavour alcohol of soup color and return sweet, Radix Phyllagathis fordii is brown.Ripe tea is in after fermentation process, under the effect of enzymatic or non-enzymatic, polyphenols, aminoacid, soluble sugar and water extraction content change, and polyphenols is oxidized to theaflavin, thearubigins and abrownin gradually, become the basic reason that raw, the ripe tea quality in Pu'er produces difference.
Folium camelliae assamicae (processed) is after fermentation, under the effect of enzyme, many new nutrient substance have been produced again, therefore on the basis of common tea, there have been again more effects, as stomach, healthy tooth tooth protection, antiinflammatory, sterilization, anti-ageing waiting for a long time are protected in: blood fat reducing, fat-reducing, blood pressure lowering, arteriosclerosis, anti-cancer, anticancer, nourishing the stomach.
The lipid-reducing function of Folium camelliae assamicae (processed) receives wide acceptance at present.But hypotensive effect never has direct experimental data support.Within 2007, even having relevant report, negates the hypotensive effect of Folium camelliae assamicae (processed).
Because current consumption habit just brews and drinks with Folium Camelliae sinensis, functional component is brewed number of times, brews temperature, brewing time etc. affects and causes stripping difference, can not utilize completely.Therefore, from Folium camelliae assamicae, effective component extracting becomes current study hotspot.
From Folium camelliae assamicae, the method for effective component extracting has a lot, according to different extracting method, can extract the different effective ingredient that obtain in Folium camelliae assamicae, Chinese patent CN200510010871.2 for example, patent CN200910069867.1, patent CN200910069869.0, patent CN200910069879.4, patent CN200910069873.7, patent CN200910228699.6 etc., these methods have all adopted water extraction substantially, filter, concentrated, (precipitate with ethanol, ) drying and other steps, but between each step and extracting parameter, all exist again difference, these differences, the difference that directly causes the product that finally obtains.
The present invention is for obtaining target product, on the basis of prior art Folium camelliae assamicae extracting method, through experimental study repeatedly, some improvement have been made again, finally drawn Folium camelliae assamicae (processed) extract of the present invention and preparation method thereof, and proved that with zoopery this Folium camelliae assamicae (processed) extract has the pharmacological action of blood pressure lowering.
