Abstract: In this study, (–)-epigallocatechin-3-gallate (EGCG) was complexed with Zn2+ ions to form EGCG-ZnII network nanocomplexes with a particle size of 50–120 nm. Compared with EGCG, the metal-phenolic network nanocomplexes exhibited significantly enhanced antioxidant capacity and maintained strong antioxidant activity across a range of temperatures and pH values. Furthermore, the nanocomplexes significantly reduced oxidative stress in both oocytes and endometrial epithelial cells. This research not only develops a food nanotechnology platform based on polyphenols but also highlights the trend toward functional and precision-oriented applications of natural bioactive food components.

Key words: natural polyphenol; (–)-epigallocatechin-3-gallate-ZnII nanocomplexes; antioxidant activity; reproductive cells
