Abstract
The reaction between (+)-catechin 1 and glyoxylic acid in model solution sy stem was investigated by LC/DAD and LC/ESI-MS analysis and the formation of new phenolic compounds 2, 3, 4 exhibiting absorption maxima near 300 nm we re observed. The structures of these compounds were elucidated by ESI-MS an d 1D and 2D NMR spectroscopy. (C) 2000 Published by Elsevier Science Ltd. A ll rights reserved.
