 "The leaves turn a variety of pinks and yellows in autumn, and sometimes have a distinctive caramel scent when in fresh autumn colours." [[https://en.wikipedia.org/wiki/Cercidiphyllum_japonicum]]
+"Maltol and sugars in the leaves of Cercidiphyllum japonicum were examined and the presence of maltol (1.8-2.3%), fructose (2.6%), glucose (3.0%), and sorbitol (1.1%) was confirmed. The high amount of sugars was correlated to the amount of maltol all the year. This correlation is interesting from biosynthetic point of view, since it has been expected that maltol is synthesized from a sugar." \\

 "[[https://en.wikipedia.org/wiki/Maltol|Maltol]] concentrations in leaves of Cercidiphyllum japonicum were quantitatively monitored during a 1 year period and were found to peak in senescent leaves. An immediately preceding peak of a bound form of maltol was isolated and identified as maltol glucoside using HPLC, HRGC, and coupled HRGC-MS." \\
