Endogenous levels of phenolics in tomato fruit during growth and maturation

Changes in the metabolism of several types of phenolics in the pulp and pericarp of tomato (Lycopersicon esculentum) fruit var. Ailsa Craig and Pik-Red were related to the stage of development. The highest levels of chlorogenic acid were found in the pulp and pericarp at the earliest stage of fruit...

Description
Summary:Changes in the metabolism of several types of phenolics in the pulp and pericarp of tomato (Lycopersicon esculentum) fruit var. Ailsa Craig and Pik-Red were related to the stage of development. The highest levels of chlorogenic acid were found in the pulp and pericarp at the earliest stage of fruit development, and quantities declined rapidly during fruit ripening. Levels of rutin, found only in the pericarp followed a similar pattern of change. The p-coumaric acid conjugate of rutin was found in low levels through fruit growth and ripening. High levels of p-coumaric acid glucoside were detected in the pulp only as the fruit matured with no rapid decline in levels during ripening. The decline of chlorogenic acid and rutin levels during fruit ripening paralleled the decline in indole-3-acetic acid levels measured previously in the pericarp tissues of these two varieties of tomato fruit during maturation. These phenolics are among those that have been suggested as regulants of auxin metabolism
