46_45/2007Cover Picture: Colorless Tetrapyrrolic Chlorophyll Catabolites Found in Ripening Fruit Are Effective Antioxidants (Angew. Chem. Int. Ed. 45/2007)

The ripening of fruit ...... is accompanied by a loss of green color (degreening) and by the typical appearance of appealing colors. In their Communication on page 8699 ff., B. Kräutler and co-workers describe the identification of chlorophyll catabolites in ripening fruit and degreened leaves from fruit trees. The availability of chlorophyll catabolites in plant-derived food and also their antioxidant activity call for attention to be paid as to their possible physiological relevance to humans and animals.
