List of fluorescent chlorophyll catabolites (Mc-FCCs) observed in extracts from peels of ripening bananas (Musa acuminata). The common general formula A is depicted below with specification of the observed covalent modifications at positions R1, R2, and R3.
| Compound | R1 | R2 | R3 |
|---|---|---|---|
| Mc-FCC-46 | CH=CH2 | O-Glc[a] | daucic acid[b] |
| Mc-FCC-49 | CH=CH2 | O-Glc[a] | daucic acid[c] |
| Mc-FCC-53 | CH=CH2 | OH | daucic acid[b] |
| Mc-FCC-56 | CH=CH2 | OH | daucic acid[c] |
| Mc-FCC-62 | CH=CH2 | OH | OH |
| Mc-FCC-71[d] | CH=CH2 | OH | OCH3 |
[a] Glc=β-glucopyranosyl, [b] bound at 5′-OH [c] bound at 4′-OH; [d] likely to be an artifact, from methanolysis of the "persistent" FCC-daucyl-esters Mc-FCC-56 and Mc-FCC-53; see the main text for details.
