茶成分对肠道菌群的调控作用及其健康效应的研究进展
摘要： 茶是世界上最受欢迎的健康饮料之一，富含茶多酚、茶多糖、茶色素和茶皂素等多种生物活性成分，对人体健康具有重要影响。肠道是一个复杂而稳定的生态系统，肠道微生态与人体健康密切相关。肠道菌群是茶成分发挥生理调节作用和健康效应的主要作用靶点，本文对近年来几种重要茶成分对肠道菌群的调节作用及其对机体健康的影响相关研究进展进行了综述。茶成分主要通过靶向肠道菌群调节糖代谢和脂代谢，减轻炎症和肠道损伤，缓解情绪和记忆障碍以及调节昼夜节律，发挥其健康效应。阐明茶成分调控肠道菌群的内在作用机制将为更好地利用茶产品来改善肠道微生态，促进人体健康提供科学依据。

Abstract:
Tea is one of the most popular health drinks in the world,with a variety of effective bioactive ingredients,including tea polyphenols,tea polysaccharides,tea pigments,tea saponins and other bioactive components,which contributes to human health.Intestinal tract is a complex and stable ecosystem,while intestinal microecology is closely associated to human health.Gut microbiota performs an important target for tea components to exert physiological regulation and health effects.Here,the progress on intervention and regulation mechanism of these tea components on gut microbiota and their effects on body health in recent years were reviewed.Tea ingredients exert their health benefits mainly by targeting on gut microbiota to regulate glucose metabolism and lipid metabolism,or relieve inflammation and intestinal damage,or alleviate mood and memory disorders,and regulate circadian rhythms.To clarify the internal mechanism of tea components regulating gut microbiota will provide a scientific basis for better utilization of tea products to improve intestinal microecology and promote human health.
Key words: tea polyphenols, tea pigments, tea polysaccharides, tea saponin, gut microbiota, health benefits
