dc.description.abstract | © 2014 American Chemical Society. Nonfluorescent chlorophyll catabolites (NCCs) and nonfluorescent dioxobilane chlorophyll catabolites (NDCCs) are the terminal compounds of the chlorophyll degradation pathway that may display beneficial properties to human health related to their antioxidant properties, which were recently shown. A profile of NCCs/NDCC of the loquat fruit Eriobotrya japonica Lindl. is described. From the 13 known different NCC structures described to date, three have been identified in loquats. Two new structures not defined so far were characterized in loquat fruits: Ej-NCC2, which corresponds to the methyl ester at C132 of Bn-NCC1 and in very low amount Ej-NDCC1, the only NDCC found in loquats. Keto-enol tautomerism at the C131 position in NCCs is described for the first time as a regular process in chlorophyll catabolism, probably through a nonspecific mechanism since almost all the chlorophyll catabolites structures detected in fruits of loquat present keto and enol tautomers. The results obtained have been possible through a high-performance liquid chromatography coupled with electrospray ionization ion trap and quadropole time-of-flight mass spectrometry fitted with a powerful postprocessing software. | - |
