Lipophilic tea polyphenols (LTP) was prepared by esterification of green tea polyphenols (GTP) with hexadecanoyl chloride. A novel long‐chain acyl catechin was isolated and purified from LTP by high‐speed countercurrent chromatography (HSCCC). Its molecular structure was elucidated as epigallocatechin‐3‐ O ‐gallate‐4′‐ O ‐hexadecanate by elemental analysis, IR, MS and 1 H NMR spectra.
