摘要：

A yellow polyphenolic compound has been isolated from black tea (fermented leaves of Camellia sinensis) and its structure characterized using a number of spectroscopic techniques. This compound, theacitrin A, represents a new class of polyphenolic pigments in black tea. (C) 1997 Elsevier Science Ltd.
