摘要： 茶是世界上最受歡迎的健康飲料之一，富含茶多酚、茶多糖、茶色素和茶皂素等多種生物活性成分，對(duì)人體健康具有重要影響。腸道是一個(gè)復(fù)雜而穩(wěn)定的生態(tài)系統(tǒng)，腸道微生態(tài)與人體健康密切相關(guān)。腸道菌群是茶成分發(fā)揮生理調(diào)節(jié)作用和健康效應(yīng)的主要作用靶點(diǎn)，本文對(duì)近年來(lái)幾種重要茶成分對(duì)腸道菌群的調(diào)節(jié)作用及其對(duì)機(jī)體健康的影響相關(guān)研究進(jìn)展進(jìn)行了綜述。茶成分主要通過(guò)靶向腸道菌群調(diào)節(jié)糖代謝和脂代謝，減輕炎癥和腸道損傷，緩解情緒和記憶障礙以及調(diào)節(jié)晝夜節(jié)律，發(fā)揮其健康效應(yīng)。闡明茶成分調(diào)控腸道菌群的內(nèi)在作用機(jī)制將為更好地利用茶產(chǎn)品來(lái)改善腸道微生態(tài)，促進(jìn)人體健康提供科學(xué)依據(jù)。

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
