Abstract: The invention relates to an electro-polymerization preparation method of an electrochemical sensor for quickly detecting EGCG (Epigallocatechin-3-Gallate), and relates to a technology in the field of active ingredient analysis and detection of an agricultural product. The method mainly comprises the following steps of: pre-treating a glass-carbon electrode; performing electro-polymerization filming on the surface of the glass-carbon electrode; and eluting template molecules to obtain EGCG molecularly imprinted membrane modified electrode, wherein the sensor can be used for quick detection of an EGCG-containing actual sample in combination of an electrochemical working station. The electro-polymerization preparation method has the advantages of high selectivity, high operation efficiency, high stability of the sensor, capability of being recycled, low cost and suitability for quick, real-time and field detection, and is suitable for quick detection of the content of the main active ingredient EGCG in tea and products thereof and quality evaluation of the tea or the tea products.
