Measurement of endogenous formaldehyde in the early developmental stages of European Turkey oak (Quercus cerris L.)

Abstract

Formaldehyde (as its dimedone adduct, formaldemethone) has been identified in the extracts of parts of European Turkey oak (Quercus cerris L.) by high performance liquid chromatography and from matrix assisted laser desorption/ionization mass spectrometric data. It has been established that the level of measurable formaldehyde is increased in the acorns by soaking. In the early developmental stages of European Turkey oak, the level of formaldehyde is particularly high throughout in the endosperm tissue and is increased gradually in the root tissues. © 1998 John Wiley & Sons, Ltd.
