We found the following in the SGS inspection project：
Epicatechin (EC) 表兒茶素 87ppm
Epicatechin in gallate (ECG) 表兒茶素沒食子酸 41ppm
Epigallocatechin (EGC) 表沒食子兒茶素 16ppm
Gallocatechin (GC) 沒食子兒茶素 11ppm
Catechin Gallate (CG) 兒茶素沒食子酸 9ppm
Function: Anti-oxidation, eliminate free radicals
Up to now, more than 134 types of catechins have been discovered, the most representative of which are free epicatechin (EC), epigallocatechin (EGC), and esterified catechins. There are four types of epicatechin gallate (ECG) and epigallocatechin gallate (EGCG).
Catechin effectively eliminates ROS and kills cancer cells to achieve anti-cancer effects. On the whole, ECG has advantages in scavenging oxides and free radicals. EC effectively scavenges free radicals but has no effect on ROS generation. The antioxidant activity of the four structures of catechins is ECG> EGCG> EGC> EC; EC;
Health benefits
Antioxidant, remove free radicals in the body
Protect cardiovascular and prevent many chronic diseases
Reduce fat accumulation, lower body fat
In recent years, studies have found that catechins have super anti-oxidant and anti-cancer capabilities. It can help the body to eliminate unstable free radicals, prevent free radicals from attacking DNA in cells, prevent gene mutations and genetic material damage, and achieve anti-cancer effects.
In addition, catechins are also very good natural cardiovascular protection substances, avoid the accumulation of blood fat, delay the oxidation of low-density lipoprotein cholesterol, which is commonly known as bad cholesterol in the body, and slow down the incidence of cardiovascular diseases.
blood vessels and the formation of thrombus. In addition, catechins can stabilize the concentration of nitric oxide (NO) in the blood vessels and provide double protection of the heart and blood vessels. Nitric oxide can help the blood vessels to relax. Studies have shown that catechins can promote the activity of nitric oxide synthase and increase the release of NO.
A Japanese study pointed out that catechins can directly affect the absorption function of the digestive organs and inhibit the activity of digestive enzymes, such as inhibiting the pancreas to secrete lipolytic enzymes, allowing large molecules of fat to enter the intestinal tract, reducing its absorption efficiency.
An American journal article pointed out that taking catechins before exercise can promote 17% of cell metabolism.
Clinical research/data
Super antioxidant power!
The strongest antioxidant power of catechins is more than 100 times that of vitamin C and 25 times that of vitamin E!
A study in the Journal of Nutrition pointed out that people in the 379mg catechin group had an effective reduction in blood pressure, fasting blood glucose and insulin resistance (2).
A Japanese study found that people who consumed 690mg of catechins per day had significantly lower body weight, body fat, waist circumference and BMI compared to those who did not take catechins.
A large clinical study with 6472 subjects showed that the tea drink group had lower body mass index BMI and average waist circumference compared with those who did not.
Anti-cancer effect
From the current scientific research results,, catechins mainly act on cancer cells from the following aspects.
Targeted attack, powerful decomposition. EGCG, EGC, ECG, EC and other substances can automatically recognize cancer cells, and can inhibit the activity of enzymes (Nox) and urokinase required for the growth of cancer cells by acting on cancer cell tissues. It also chemically decomposes cancer cells and inhibits synthesis without harming normal healthy cells. EGCG, EGC, ECG, EC and other substances can prevent proliferation, bind to tumor receptors of healthy cells, prevent the formation of carcinogenic benzopyrene inducers and nitroso compounds, inhibit the covalent binding of oncogenes to DNA, and prevent Cancer cell proliferation induces apoptosis.
environment of cancer cells, cut off the proliferation pathway of cancer cells, and kill cancer cells by inhibiting synthesis and chemical decomposition, that is, inducing cancer cell apoptosis, enhancing immunity, and resisting radiation. EGCG, EGC, ECG, EC and other substances can remove free radicals in the human body. Delay aging and enhance the body’s non-specific immunity. It can obviously eliminate leukopenia caused by radiotherapy and chemotherapy, and has a strong whitening effect.
Note:
Academic research shows that the EGCG, EGC, ECG, EC and other substances of fermented tea have more anti-cancer effects than unfermented tea. Therefore, in comparison, Pu’er tea and Oolong tea rank high, while green tea ranks low and even has no effect.
