Abstract
The present invention relates to the extracting method of water-soluble tea component in a kind of tea extract and the Folium Camelliae sinensis, specifically, be a kind of being made of abrownin, theaflavin, thearubigins three of extracting from Folium Camelliae sinensis, and the three has the medicinal tea pigment and the production method thereof of constant ratio.The abrownin weight content is 13-16% in the tea pigment of gained of the present invention, and the weight content of theaflavin is 1-4%, and the weight content of thearubigins is 4-7%.The production process of tea pigment is, Folium Camelliae sinensis is through decocting extracting juice, and alkalization concentrates, and acidify adds alcohol reflux, and alcohol reflux liquid alkalizes and obtains the tea pigment crystallization, and the tea pigment crystallization promptly gets this tea pigment through vacuum drying.Thereby the tea pigment of gained of the present invention is a kind of Nantural non-toxic reduces the prevention of the cardiovascular disease of blood viscosity cholesterol reducing, the new drug of treatment efficiently.
Description
The present invention relates to the extracting method of water-soluble tea component in a kind of extract of tea and the Folium Camelliae sinensis, specifically, is a kind of tea pigment and production method thereof.
In the prior art, do not detect constituting of from Folium Camelliae sinensis, extracting, and the three there are the water soluble tea pigment and the production method thereof of constant proportion of composing by abrownin, thearubigins, theaflavin three; On November 5th, 1986 Decree of Patent Office of China a kind of " preparation method of black tea colorant ", application number: 85103794, wherein black tea colorant is through chemical oxidation by green tea or fresh tea leaf in its, and directly make, though in the Folium Camelliae sinensis utilization, be improved, but do not relate to yet use from Folium Camelliae sinensis, extract by abrownin, thearubigins, tea yellow three constitute, and the three has the water soluble tea pigment and the production method thereof of constant proportion of composing.
The object of the present invention is to provide a kind of forming of from Folium Camelliae sinensis, extracting, and the three there are the water-soluble pesticide tea pigment and the production method thereof of constant proportion of composing by abrownin, thearubigins, theaflavin three.
For achieving the above object, tea pigment of the present invention is the brown amorphous powder, is a kind of abrownin that comprises.The water colo(u)r of thearubigins, theaflavin is characterized in that: the weight content of abrownin is 13-16%, and the weight content of theaflavin is 1-4%, the weight content 4-7% of thearubigins.The pH value of this product 0.1% pure water solution is 8-9; 0.1% pure water solution is at 280nm, the absorption value E in the thick cuvette of 10mm
280nm 1cm〉=3.0.Soluble in water and the ethanol of this grade, its water or alcoholic solution are the clear and bright solution of brown, no suspendible or muddiness.Add FeCL in this product aqueous solution
3Test solution generates green gloomy shallow lake; Dripping the colourless flocculent deposit of glutin test solution produces; The loss on drying amount is less than 5%, residue on ignition by sulfate less than 35%.The production method of above-mentioned tea pigment is as follows: (a) Folium Camelliae sinensis is by 1: 15-30 extraordinarily water after once or once above decoction extracting juice, fried liquid is used in the aqueous solution can produce OH
-Ionic chemical compound alkalizes, and regulates PH8-10, at the 1/4-10 that heats concentrated this alkaline solution to the original volume amount down less than 70 ℃, gets concentrated solution then;
(b) concentrated solution transfers to PH3-6 with acid, and acidifying solution adds ethanol 1-10 volume doubly to be measured, and backflow 0.5-2 hour, gets alcohol reflux liquid;
(c) alcohol reflux liquid is used in the aqueous solution and can produces OH
-Ionic chemical compound is adjusted to PH7-10, and post precipitation filters, and gets the tea pigment crystallization, and the tea pigment crystallization promptly gets this tea pigment product through vacuum drying.
Above-mentionedly in aqueous solution, can produce OH
-Ionic chemical compound is preferably sodium hydroxide, sodium carbonate, sodium bicarbonate.The decocting time that a step Folium Camelliae sinensis adds behind the water is best for 0.75-1. hour, is beneficial to the stripping and the maintenance of tea pigment; The acid of being adopted is preferably hydrochloric acid, oxalic acid, acetic acid.
The present invention compared with prior art, the following advantage of tool: the tea pigment composition is complete, thereby is that a kind of Nantural non-toxic reduces the prevention that the cardiovascular disease of blood ester cholesterol reducing falls in blood viscosity efficiently, the treatment new drug, have very big economic benefit and social benefit.This method raw material can adopt various height, low and middle-grade Folium Camelliae sinensis, and wide material sources are cheap, and the tea pigment extraction ratio can reach more than 30%.
Accompanying drawing is a visible ultra-violet absorption spectrum of the tea pigment of embodiment 1 gained.
The invention will be further described below in conjunction with embodiment:
Embodiment 1, and broken green tea 40kg mixes three decoctions of moisture that weigh 20 times of amounts in the moistening rearmounted jacket steam pot with Folium Camelliae sinensis thoroughly with 1: 1 water purification in two-way blender, and the back of at every turn boiling kept 20 minutes.Merge three fried liquid and advance plate-and-frame filtration, filtrate adds sodium hydroxide solution to PH9 under continuous stirring in transferring the alkali still, be concentrated into 1/5 of original volume amount 65 ℃ of thin film evaporation at once, after alkalization tea juice after concentrating is put in the reactor and to be transferred to PH3 with hydrochloric acid, add the ethanol that 2 volumes are doubly measured, the half an hour of refluxing, emit backflow after cooling and put in the alkalization still and transfer to PH9 with sodium hydroxide, can get the tea pigment crystallization, final vacuum be filtered in this crystallization be drying to obtain tea pigment 4kg.
This tea pigment is a brown powder, and wherein the abrownin weight content is 14%, and the theaflavin weight content is 3%, and the thearubigins weight content is 6%.An its visible ultra-violet absorption spectrum is seen accompanying drawing, the visible absworption peak at the 280nm place.
Embodiment 2, black tea 30kg, the water of 15 times of amounts of adding is put in the jacket steam pot and is decocted, kept 45 minutes after boiling, fried liquid alkalizes to PH8 in transferring the alkali still with sodium carbonate liquor, heat down at 68 ℃ then and concentrate this alkaline solution to 1/4 of stock solution volume, get concentrated solution, after alkalization tea juice after concentrating transfers to PH5 with acetic acid, put in the reactor and got alcohol reflux liquid in 1.5 hours by refluxing behind 1: 5 the volume adding ethanol, emit backflow after the cooling and put alkalization and transfer to PH8 with sodium carbonate liquor in the still, can get the tea pigment crystallization, final vacuum is filtered in this crystallization be drying to obtain tea pigment 3.2kg.This tea pigment is a brown powder, and the abrownin weight content is 16%, and the theaflavin weight content is 2.5%, and the thearubigins weight content is 4%.
