Abstract
A process for extracting tea pigment features the combination of immersion, extraction and column separation for high purity and complete active components. The extract contains theaflavin, theaproten, theabrown and catechin and can be used to reduce blood fat
Description
The invention provides a kind of method of from tealeaves, extracting tea pigment.This tea pigment contains theoflavin, thearubigins, theabrownin and catechin.
Method
1, tealeaves is mixed with (W/W is 1: 10) with 80% ethanolic soln, soaking at room temperature 2 hours, reflux 1 hour removes by filter tealeaf residue.
2, the hydrochloric acid conditioning solution pH value of adding 1mol/L is 3.2 in the filtrate, and room temperature was placed 30 minutes, and centrifugal 30 minutes of 10000rpm abandons precipitation.
3, getting the sodium hydrate regulator solution pH value that supernatant liquor adds 1mol/L is 7.0, is splined on sephadex column (Sephadex LH-20), and the ethanolic soln with 40%-100% carries out wash-out.
4, the pH value of the sodium hydrate regulator solution of elutriant adding 1mol/L is 8.0, and the adding methylene dichloride extracts.Remove water, wave diffusing solvent for 40 ℃, promptly obtain the tea pigment powder.Pharmacological experiment 1, experimentation on animals (1) security test
This extract tea pigment is irritated stomach with 100 times of human dosage to rat, observe a week, do not see that rat has abnormal conditions.The result shows, this extract safety non-toxic.(2) reducing blood lipid
The hyperlipemia rat animal model is raised with this extract tea pigment.After 1 month, compare, observe every index with control group.Tea pigment shows result's (seeing accompanying drawing 1) of the therapeutic action of hyperlipemia rat, compares with control group, observes every index.The result shows that this extract can effectively reduce total cholesterol in the blood (TC), reduces low-density lipoprotein (LDL), the effect of triglyceride reducing (TG) and high density lipoprotein increasing (LDL).2, human experimentation (1) is to the effect of hyperlipidemia
Below be normal people's TC, TG, HDL, the LDL value:
TC?????3.1?—5.7mol/L
TG?????0.56—1.7mol/L
HDL????1.04—1.55mol/L
LDL????1.80—3.36mol/L
Altogether 1,696 hyperlipidemia patient is tested.Wherein the male sex is 920,776 of women, and the age, the mean age was 58.9 ± 7.9 years old between 35 to 81 years old.Patient takes this tea pigment every day 3 times, and each 1 (125mg) obeyed for 4 weeks altogether.Tea pigment is seen accompanying drawing 2 and following table 1 and 2 to hyperlipidemia patient's exercising result.
Patient need meet following standard: 1) no acute heart disease, no brain damage, wound need be after accepting other operation after at least 6 months.2) athyreosis disease 5 no kidney disease 3) non-diabetic 4)) do not have three phase hypertension 6) no drug-induced hyperlipidemia 7) Wuhuai pregnant woman woman
