Profile of abundance of Mc-FCCs during ripening of bananas. The relative amounts of three main Mc-FCCs in peels of ripening bananas are depicted as a function of the time of storage at room temperature, beginning with the day of their acquisition (day 0, at ripening stage (rs)=5) and analyzed on the following four days (senescence-associated dark spots typically appear on days 3 and 4); FCC fractions were extracted from 3–5 banana peels at the indicated days; for quantitative analysis, the peak areas of the three FCCs in the fluorescence traces of HPL-chromatograms were determined individually; the averaged data given here was obtained by dividing the total area by the number of determinations.
