Abstract

The biosynthesis of octane-1,3-diol and 3-hydroxy-octyl-β-D- glucopyranoside was investigated by administering [1-14C]hexanoic acid, [1- 14C]octanoic acid and [U-14C]linoleic acid into intact ripe apple fruits cv. Peau de Chien. After a storage period of 2 months at 4, the metabolites were isolated by solid phase extraction and analysed by HPLC and TLC. The fatty acids were converted to octane-1,3-diol with incorporation rates of 3.9, 3.4 and 16.2% and to 3-hydroxy-octyl-β-D-glucopyranoside with transformation rates of 0.9, 0.4 and 3.0% for hexanoic, octanoic and linoleic acid, respectively. No other major metabolites were detected. Enzymatic hydrolysis of the solid residues released additional amounts of [14C] octane-1,3-diol.
