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.
