In a cold‐requiring variety of endive (chicory, Cichorium intybus L. ev. Witloof) we could demonstrate a relationship between the variations in the content of chlorogenic acid during the cold treatment of the roots and their disposition to produce flowers in vitro . An increase in the level of chlorogenic acid in the roots preceded the development of their aptitude to form flower buds. In addition, the three main forms of “isochlorogenic’ acid are present in the roots of this cultivar: 3,5‐dicaffeoyl‐quinic acid, 3,4‐dicaffeoyl‐quinic acid, and traces of 4,5‐dicaffeoyl‐quinic acid. The variations in the levels of chlorogenic and “isochlorogenic’ acids indicate that part of the chlorogenic acid (3‐caffeoyl‐quinic acid) is converted to 3,5‐dicaffeoyl‐quinic acid.
