Extraction, Isolation and Purification of Catechins and their Applications

Abstract: Catechins, the main active components of tea polyphenols, boast remarkable antioxidant activities because of their unique structures. This translates to a range of potential health benefits, including fighting antibacterial, inflammation, and even cancers. However, extracting these beneficial compounds can be tricky as they're prone to degradation. Thankfully, recent advancements have yielded successful methods for isolating and purifying catechins, allowing us to obtain them in their purest form. The power of catechins isn't just theoretical. In vitro and in vivo studies have demonstrated promising results in treating various conditions like inflammation, cancer, neurodegenerative diseases, cardiovascular diseases, diabetes, and more. This review dives deep into the methods used to extract, isolate, and purify catechins. Additionally, it explores their potent antioxidant activities and exciting possibilities for future applications.
