 Title    Metabolism of Ferulic Acid Sucrose Esters in Anthers of Tulipa cv. Apeldoorn: I. The Accumulation of Esters and Free Sugars  
 Abstract    The authors of Tulipa cv. Apeldoorn accumulate a large amount of ferulic acid sucrose esters. In addition to the well-known diferuloyl-(DFS) and triferuloyl sucrose esters (TFS), a new phenylpropanoid characterized as a monoester of ferulic acid and sucrose is described. Like TFS and DFS, this ester exhibits an accumulation maximum in the early stages of pollen development. Numerous free sugars have been extracted from Tulipa anthers. Three of them were identified as sucrose, glucose and fructose. Sucrose as the main component is accumulated in extremely high amounts during specific developmental stages (= 20% of the dry weight). After separation of the anthers into an anther wall fraction (AWF) and pollentapetum (PTF), each fraction shows a different accumulation kinetic of the free sugars and the ferulic acid esters. A correlation could be observed between the occurrence of the esters and sucrose in the pollen-tapetum fraction during the anther development.
