Technical Data Sheet
| Product Name | Green Tea extract  |
| Latin Name | Camellia sinensis L |
| Part of Plant | Leaves of Green Tea |
| Active Ingredient | Catechins 20% ~ 80% |
| CAS NO. | 154-23-4 |
| Chemical Formula | C15H14O6 |
| Solubility | Soluble in hot water, ethanol, glacial acetic acid, acetone, slightly soluble in cold water and ether, almost insoluble in benzene, chloroform and petroleum ether |
| Stability | Catechin has various pharmacological effects such as anti-tumor, anti-oxidation, anti-bacteria, and protection of the heart and brain organs. These pharmacological activities are mainly determined by its polyhydroxy structure. However, the polyhydroxy structure also makes catechin in neutral and alkaline. The structure is unstable under the conditions. |
| Description | Catechin has obvious phenolic properties and can precipitate heavy metals and proteins, so it is a phenolic substance. It accounts for about 75% to 80% of the content of tea polyphenols, and is also one of the sources of tea's bitter taste. Since phenolic substances can precipitate proteins, they have the properties of tanning raw hides into leather in different sizes, so they are also called tannins or tannins. Compared with some typical vegetable tannins (gallic tannins, etc.), the performance of catechins in tanning leather is weak. Catechin is a general term for polyhydroxyflavan-3-phenols, but sometimes refers to (+)catechins. Widely distributed in the plant kingdom, it exists in abundance with tannins in the bark of Acacia catechu and gambir. The effect of tannin is very weak, but it is easy to overlap to form tannins by heating and acid treatment. The 2,3 position has diastereomers due to irregular carbon atoms |

| Bio-pharmaceuticals | ￭ Control obesity The catechins in green tea have obvious effects on human body fat metabolism and fat distribution, especially the reduction of visceral fat. ￭ Prevent cardiovascular disease, prevent cancer. ￭ Free radical scavenging: Catechin is a natural oil antioxidant, and its antioxidant activity is even higher than that of vitamin E.. ￭ Delay aging: Because of the function of scavenging free radicals, it can slow down aging. ￭ To prevent tooth decay: Because tea contains fluorine, it can make teeth have strong resistance to acid erosion ￭ Alter the distribution of gut microbes: Catechins can inhibit human pathogenic bacteria (such as botulinum toxin) without harming the reproduction of beneficial bacteria (such as lactic acid bacteria), so they have the function of regulating the intestines ￭ Antibacterial effect: It can inhibit the bacteria that cause human skin diseases, and has a good effect on the treatment of eczema ￭ Deodorization: Catechin can remove the odor of methyl mercaptan, so it can remove the bad breath of smokers, and reduce the odor of pig, chicken and human excrement ￭ Inhibit blood pressure (can reduce diastolic and systolic blood pressure) and blood sugar (inhibit glycolytic enzymes), reduce blood cholesterol and low-density lipoprotein (LDL), and increase the amount of high-density lipoprotein (HDL), anti-radiation and ultraviolet rays |
