Schematic representation of the synthesis, extraction, and purification method of TFs from black tea and the extraction principle of magnetic molecularly imprinted polymers (MMIPs) for bioactive compounds. MMIPs will be a promising method for the preparation of TFs with high purity. Abstract Theaflavins (TFs) are a kind of bioactive compound that formed during the fermentation stage of black tea. TFs play a vital role both in the sensory quality and the biological activity of black tea. However, the complex composition of black tea and the low ...
