Methyl esters of acyclic terpenic acids were isolated from the roots of Cyperaceae plant, and analyzed by gas chromato-graphy-mass spectrometry. The characteristic ion at m/e 114 was found in the all of their mass spectra. The structure of this ion is identified as CH2=C(CH3)-CH=C(OCH3)OH+on the basis of the mass spectra of the derivatives and deuterium labelling studies. The characteristic ion at m/e 100 was found in the mass spectra of nonbranched α, β-unsaturated fatty acid methyl esters. These ions were useful to clarify the structure of the methyl esters of acyclic acids and α, β-unsaturated fatty acids.
