Die blaue Lumineszenz reifender Bananen

Abstract: Wie wäre es mit einer blauen Banane? Reifende Bananen zeigen unter UV‐Licht eine intensive blaue Lumineszenz. Die Quelle dieser Lumineszenz sind fluoreszierende Chlorophyll‐Kataboliten, die sich während des Reifeprozesses in der Bananenschale aufgrund einer bisher unbekannten Modifikation anreichern, die die weitere natürliche Umwandlung in nichtfluoreszierende Chlorophyll‐Kataboliten spezifisch hemmt.

“…[21,22] The naturally accumulating hm FCCs induce (the peels of) ripening bananas to fluoresce blue when excited by UV light. These luminescent products of chlorophyll breakdown may, thus, serve as a specific communication with the exterior world.…”

“…Eine Überraschung brachte die Analyse der gelben Schalen reifer Bananen (Musa acuminata, Cavendish‐Sorte), in welchen sich polare FCCs als Chl‐Abbauprodukte anreichern (Abbildung 7) 15. FCCs galten als kurzlebige Zwischenprodukte im Chl‐Abbau, die in den schwach sauren Vakuolen schnell zu den stabileren NCCs isomerisieren 4,9.…”

“…Persistent hmFCCs are sources of remarkable "fluorescence" signals [10] and effective sensitizers of the endogenous, light-induced formation of singlet oxygen ( 1 O 2 ), [11] and may have further biological roles in plants. [12] The recent discovery of yellow Chl catabolites (YCCs) and pink chlorophyll catabolites (PiCCs) (see Scheme 2) in senescent leaves of the Katsura tree (Cercidiphyllum japonicum) [13] and of other deciduous plants [14] indicated further oxidative transformations of NCCs, which are noted antioxidants. [15] However, a pathway for the suggested endogenous formation of YCCs and PiCCs has remained elusive.…”
