ABSTRACT: Fresh leaves of black tea are crushed and allowed to undergo oxidation induced by polyphenol oxidase resulting in the formation of poly phenolic dimer known as theaflavins. Tea and its derivatives have different polyphenol profiles, which are the bioactive chemical entities. This study was designed to confirm the presence of theaflavin in Camellia sinensis extract and the development of chitin–theaflavin bioconjugates. They were analysed by applying spectrometry, TLC, FT-IR, and GC-MS. The advantages of such a product could be effected on drug delivery in chronic disorders viz., diabetic, anti-inflammatory, protective agents against cardiovascular and cerebrovascular diseases, aging etc.
