PRESENCE OF HYDROXYCINNAMIC ACIDS AMIDES IN CHRYSANTHEMUM (CHRYSANTHEMUM X MORIFOLIUM RAMAT)

The study of the amides of hydroxycinnamic acids had never been done in chrysanthemum (Chrysanthemum X morifolium Ramat). Those molecules, apparently widely distributed in the vegetal kingdom, seem to play a non-neglectible role in various physiological processes such as reaction to infection, flowering… In chrysanthemum, a method of bidimensional paper chromatography suggest that they are present in the flowers (particularly "neutral" types) in larger amounts in the inflorescences with bisexual flowers than in those with only unisexual ligulate flowers.

The determination of those compounds with help of other methods of analyse, the qualitative and quantitative following of their evolution in the plant and their possible role(s) should have to be pursued.
