Catechins extracted from natural plants

Catechin, the English name is Catechin, also known as catechin, catechin (Caredhieacid), is a class of phenolic active substances extracted from natural plants such as tea. The relative molecular mass of catechin is 290.28; it is white needle crystal (water-acetic acid), melting point 212 ~ 216 C, soluble in hot water, ethanol, glacial acetic acid, acetone, slightly soluble in cold water and ether, almost insoluble in benzene Chloroform and petroleum ether. Catechin has various pharmacological effects such as anti-tumor, anti-oxidation, anti-bacteria and protection of heart and brain organs. These pharmacological activities are mainly determined by its polyhydroxy structure. However, the polyhydroxy structure also makes catechins neutral and alkaline. The structure is unstable under conditions. After catechins are ingested by the human body, methylation or glycosylation will occur quickly under the action of biological enzymes. Studies have f…
