Abstract

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.
