儿茶素类物质是茶叶的有效成分,具有多种生物活性,对人体有多种有益作用。本文阐述了儿茶素类物质的吸收情况(包括吸收部位、速度、参与吸收的可能载体以及影响吸收的因素等);分布情况(包括给予多长时间后在组织中可检测到儿茶素类物质、何种组织中的浓度最高等);生物转化情况(包括参与转化的主要酶类COMT、UGT、SULT的存在部位、作用形式及产物等)以及主要的排泄途径等4个方面,以期为更好地认识、利用、开发儿茶素类物质提供参考。 Catechins are the active ingredients of tea, with a variety of biological activity, a variety of beneficial effects on the human body. This article describes the absorption of catechins (including absorption site, velocity, possible carriers involved in absorption, and factors affecting absorption); distribution (including how long catechins can be detected in tissues Substance and tissue, etc.); biotransformation (including the main enzymes involved in transformation such as COMT, UGT, SULT’s site of action, forms of action and products, etc.) and the main excretion pathway, in order to To better understand, use, and development of catechins provide a reference material.
