Ellagic acid (EA) is a biologically active phenolic compound widely present in plant tissues such as fruits and nuts, with its structure shown in Figure 1. It is a dimeric derivative of gallic acid. In nature, ellagic acid mainly exists in condensed forms, such as ellagitannins. Ellagic acid is essentially non-toxic and has a significant inhibitory effect on chemically-induced carcinogenesis and various types of cancers, including colon cancer, liver cancer, lung cancer, prostate cancer, breast cancer, lymphoma, and others. Additionally, ellagic acid also exhibits antioxidant, anti-inflammatory, antibacterial, melanin inhibition, and leukemia improvement effects. Due to its excellent biological activity, ellagic acid is widely used in health foods, medicine, pharmaceuticals, cosmetics, and other fields. Studies have shown that tea is an important dietary source of ellagitannins and ellagic acid, which are converted from ellagitannins through human gut microbiota metabolism. ▲ Human Metabolic Pathway Pu'er ripened tea, a famous Yunnan tea, is a unique microbial-fermented tea made from large-leaf sun-dried green tea.
