(-)-表儿茶素没食子酸酯简介

Epicatechin gallate (ECG) is a flavan-3-ol, a type of flavonoid, present in green tea. It is also reported in buckwheat and in grape.
The tea component epicatechin gallate is being researched because in vitro experiments showed it can reverse methicillin resistance in bacteria like Staphylococcus aureus. If confirmed, this means the combined intake of a tea extract containing this component might also enhance the effectiveness of methicillin treatment against some resistant bacteria in vivo.; Epicatechin, as well as many other flavonoids, has been found to act as a non-selective antagonist of the opioid receptors, albeit with somewhat low affinity.
