Suppression de la production d'oxygène singulet sensibilisé à la riboflavine par l'acide l-ascorbique, l'acide 3-O-éthyl-l-ascorbique et le Trolox.

La riboflavine (RF), une vitamine B2 soluble dans l’eau, est un photosensibilisateur endogène d’oxygène singulet dans la peau et les yeux. Les profils temporels de la phosphorescence dans le proche infrarouge de l'oxygène singulet généré par RF ont été mesurés en l'absence et en présence d'acide l-ascorbique (AA, vitamine C), d'acide 3-O-éthyl-l-ascorbique (3-EtAA) et Trolox (TX, un analogue soluble dans l'eau de la vitamine E) dans un tampon phosphate (pH 6,8). Ces substances suppriment la génération d'oxygène singulet photosensibilisé par RF. Par exemple, le rendement quantique de la génération d'oxygène singulet est réduit d'un tiers en ajoutant 0,4 mmoldm (-3) AA ou TX (la concentration en oxygène dissous dans de l'eau saturée en air est de 0,27 mmoldm (-3)). AA et TX sont des suppresseurs plus efficaces de la génération d'oxygène singulet photosensibilisée par RF que le 3-EtAA. Les constantes de vitesse bimoléculaires pour l'extinction des états singulet et triplet excités de RF par AA, 3-EtAA et TX ont été déterminées par des mesures de fluorescence et d'absorption transitoire. Ces mesures suggèrent que la suppression observée est due à la désactivation des états singulet et triplet excités de RF par AA, 3-EtAA et TX. Les constantes de vitesse bimoléculaires pour l'extinction de l'oxygène singulet par AA, 3-EtAA et TX ont été déterminées comme étant 1,8x10 (8), 0,27x10 (8) et 4,4x10 (8) mol (-1) dm (3) s ( -1), respectivement.
