Abstract
The present invention provides a kind of Pu-Er ripe tea extract, preparation method is：Take Pu'er cooked tea, add water to cook, tea grounds discards, extracting solution concentration after plus ethyl alcohol stand, precipitation and separation, supernatant drying to get.And application of the Pu-Er ripe tea extract in blood-pressure drug or health food is prepared.
Description
Technical field
The present invention relates to pharmacy and field of health care food, specially a kind of Pu-Er ripe tea extract and preparation method thereof and its
Application in treatment blood-pressure drug or health food is prepared.
Background technology
With its long history, the charm of rich culture and glycol is world known yunnan puer tea.Pu'er tea originates in
Ground is mainly in the Simao Diqu in Yunnan and Xishuangbanna.With the popularization of large leaf, Sichuan, Guangdong, Guangxi also become Pu'er tea
The province of production.In recent years, with the development of economy, the health care consciousness enhancing of people, health, health care become ordinary people
The theme of daily life, Pu'er tea have attracted the extensive pass of various circles of society, especially each side scholar with its unique health-care efficacy
Note, civil is even more to have risen one upsurge for buying Pu'er, hiding Pu'er, drinking Pu'er therewith.
By processing technology and qualitative characteristics, Pu'er tea is divided into two kinds of Pu'er tea life tea and puerh tea.Raw tea is by great Ye
Kind sun withering tea is made through techniques such as tidewater, steam pressure moldings, and Appearance color is blackish green, greenish-yellow limpid, the dense time sweet, tea residue of flavour of soup look
It is plump yellowish green.Ripe tea needs the zymotechnique after in process, Appearance color is reddish brown, red dense bright, the flavour alcohol of soup look and
Return it is sweet, tea residue is reddish brown.Ripe tea is in rear fermentation process, under the action of enzymatic or non-enzymatic, polyphenols, amino acid, can
Dissolubility sugar and water extraction content change, and polyphenols is gradually oxidized to theaflavin, thearubigin and theabrownin, becomes
The basic reason of raw, the ripe tea quality generation difference in Pu'er.
After Pu'er cooked tea is fermented, under the action of enzyme, and many new nutriments are produced, therefore in common tea
On the basis of, and have more effects, such as：Lipid-loweringing, weight-reducing, blood pressure lowering, anti arteriosclerosis, anti-cancer, anticancer, nourishing the stomach and protecting stomach, healthy tooth
Protect tooth, anti-inflammatory, sterilization, anti-aging etc..
The lipid-reducing function of Pu'er cooked tea has received wide acceptance at present.But antihypertensive effect never directly experiment
Data are supported.Even there is relevant report within 2007, negate the antihypertensive effect of Pu'er cooked tea.
It is drunk since current consumption habit is only brewed with tealeaves, when functional component is brewed number, soaking temperature, brewed
Between wait influence and cause dissolution difference, it is impossible to be fully utilized.Therefore, effective component extracting becomes current research from Pu'er tea
Hot spot.
The method of effective component extracting has much from Pu'er tea, according to different extracting methods, can extract to obtain general
Different active ingredients in Pu'er tea tea, such as Chinese patent CN200510010871.2, patent CN200910069867.1, patent
CN200910069869.0, patent CN200910069879.4, patent CN200910069873.7, patent
CN200910228699.6 etc., these methods be substantially all employ water carry, filter, concentrating,（Alcohol precipitation,）Drying and other steps,
But all there is differences again between each step and extracting parameter, these are different, directly result in the difference of the product finally obtained.
The present invention is obtains target product, on the basis of prior art Pu'er tea extracting method, by experiment repeatedly
Research, and it is made that some improvement, finally obtain the Pu-Er ripe tea extract and preparation method thereof of the present invention, and real with animal
Verification understands that the Pu-Er ripe tea extract has the pharmacological action of decompression.
