In addition, it additionally has a small amount of (+)-GC, GCG, CG, (+)-C. Among the catechins, EGcG and ECG are the main components, accounting for regarding 50% and also 15% of the complete catechins, specifically.

Catechin Uses

➀ Feed on cost-free radicals
Catechin is a natural oil anti-oxidant, and also its antioxidant task is even more powerful than that of vitamin E. And it can remove free radicals produced by the body to shield cell membrane layers.

➁ Hold-up aging
It has the feature of scavenging complimentary radicals as well as can decrease aging.

➂ Protect against tooth decay
Tea consists of fluorine, so it can make teeth much more resistant to acid disintegration. In addition, scientific trials have actually likewise pointed out that catechins can dramatically lower oral plaque and decrease gum illness.

➃ Adjustment the circulation of intestinal microorganisms
Catechins can hinder human pathogenic germs (such as botulinum contaminant) without harming the reproduction of useful germs (such as lactic acid microorganisms), so they have the feature of managing the intestinal tracts.

➄ Antibacterial impact
It can prevent the bacteria that cause human skin diseases, and has an excellent result on the therapy of eczema.

➅ Deodorization
Catechin can remove the smell of methyl mercaptan, smokers’ bad breath, and also reduce the odor of pig, poultry and human excrement (catechin can stand up to the bacteria that create smell in the human intestinal tract).

➆ Others.
There are also some research studies revealing that Catechin can additionally subdue blood pressure (can decrease diastolic high blood pressure and also systolic high blood pressure) and also blood glucose (inhibit glycolytic enzymes), reduce blood cholesterol and also low-density lipoprotein (LDL), as well as rise high-density lipoprotein (HDL). (utilized in Japan to make low-cholesterol eggs), anti-radiation as well as ultraviolet rays (the United States has actually made cosmetics to stop ultraviolet rays), anti-mutation (verified in microbes, but there are no reports on human trials).

Catechin Application

The whole plant of Rubus parvifollus L has actually successfully reduced the signs and symptoms of people with Parkinson’s illness. For additional research, we extracted catechin from Rubus parvifollus L and also made use of MPTP (1-methyl -4-phenyl-1,2,3,6-tetrahydropyridine) and MPP+(1-methyl-4-phenylpyridinium ion) were made use of to prepare Parkinson’s illness pet designs. The study located that Catechin can dramatically minimize Parkinson’s disease in animals. signs and symptoms.

Pharmacological experiments show that it has a protective intervention result on the fatality of substantia nigra nerve cells, a protective effect on dopamine nerve cells in the forward midbrain cultured artificial insemination, rescues the loss of dopamine neurons, and inhibits the reduction of striatal dopamine concentration caused by MPTP. It improves the behavioral abnormalities of PD computer mice, so it has a “fundamental” impact on Parkinson’s disease.

Additionally, more experiments have actually shown that the substance can be made use of to deal with a range of neurodegenerative illness characterized by “nerve cell fatality”, not only for PD, but also for other neurodegenerative diseases such as advertisement, amyotrophic lateral sclerosis (ALS) ), neurofibromatosis, Huntington’s disease, myoclonic epilepsy, familial blindness, demyelinating illness, spinal cord injury, etc. It additionally has high application value. At the same time, experiments have revealed that its restorative index High, excellent safety.

Catechin Preparation

The whole plant of the Rubus parvifollus L plant in the Rosaceae household is used, and its dry powder is used to reflux as well as extract with ethanol numerous times, and also the ethanol is recuperated from the remove. Use petroleum ether to get rid of fat-soluble components from the deposit, then suspend it in water, remove with ethyl acetate, liquify the extract in methanol, combine with silica gel as well as travel through the chromatography column, elute with petroleum ether: ethyl acetate slope, as well as separate light yellow needle crystals. Sex-related element.

We discovered that this active ingredient is quickly soluble in solvents such as methanol, ethanol, and also alkaline liquid services; soluble in solvents such as ethyl acetate and also acetone; slightly soluble in water; and also insoluble in solvents such as chloroform, petroleum ether, diethyl ether, and methylene chloride. According to the above extraction technique, the return has to do with 1 ‰, as well as the element turns red when it experiences concentrated sulfuric acid remedy of sugar. After recognition, the ingredient is Catechin.
