The fragmentation mechanisms leading to the major ions in the mass spectra of the trimethylsilyl derivatives of zingerone, the gingerols, shogaols, gingediols, gingerdiones and hexahydrocurcumins from ginger (Zingiber offieinale Roscoe) were studied with the aid of deuterium labelling and high resolution mass measurements.

Mass spectra of 69 alcohols from methanol to undecanol have been studied in order to find correlations of fragmentation patterns with molecular structure.On the basis of spectra, primary alcohols Bave been subclassified into (1) straight-chain and branched on or beyond the 7-carbon atom, and (2) branched on the j3-carbon atom.
