Pu-erh tea is a post-fermentation tea with unique flavor and multiple health benefits. Due to the various microorganisms involved in the post-fermentation process, Pu-erh tea contains highly complex components, which have rich interactions with the gut microbiomes (GMs). Because the structure and homeostasis of GMs are closely related to human wellness and the various diseases progress, the beneficial effects of Pu-erh tea on GMs have a great potential for application in health care. However, there is no systematic summary of the bioactive components of Pu-erh tea, and their effects on the GMs. Here, we review the current studies on the effects of Pu-erh tea and its bioactive components on the structure of GMs as well as on health improvement, and further discuss the relevant quality indicators. This "components - function - indicators" clue will hopefully stimulate the standardization of Pu-erh tea fermentation process and the development of its functional products.
普洱茶是一种具有独特风味和多种健康益处的后发酵茶。由于后发酵过程中涉及多种微生物，普洱茶含有高度复杂的成分，这些成分与肠道微生物群（GMs）有着丰富的相互作用。由于GMs的结构和稳态与人类健康及各种疾病的进展密切相关，普洱茶对GMs的有益作用在医疗保健方面具有巨大的应用潜力。然而，目前尚无关于普洱茶生物活性成分及其对GMs影响的系统总结。在此，我们综述了当前关于普洱茶及其生物活性成分对GMs结构以及健康改善影响的研究，并进一步讨论了相关质量指标。这条“成分 - 功能 - 指标”线索有望推动普洱茶发酵过程的标准化及其功能性产品的开发。
