Manufacture of wood-cement boards VII: cement-hardening inhibitory compounds of hannoki (Japanese alder,Alnus japonica Steud.)

Abstract

To identify the cement-hardening inhibitory components of hannoki (Japanese alder,Alnus japonica Steud.), methanol extractives were fractionated by successive organic solvent extraction and column chromatography. Chromatographie analysis and inhibitory indices of the solvent-soluble fractions suggested that glucose and sucrose seem to be the main cement-hardening inhibitory components of Japanese alder. As these compounds are metabolized in vivo even after cutting, the particles after withering are desirable as raw material for wood-cement board.
