VOLATILES FROM STRAWBERRIES. II. COMBINED MASS SPECTROMETRY AND GAS CHROMATOGRAPHY ON COMPLEX MIXTURES.

W. H. McFadden; Roy Teranishi; J. Corse; Dale R. Black; T. R. Mon

Abstract The technique of combined mass spectrometry and gas chromatography has been applied to the analysis of a complex oil of strawberry volatiles. Capillary gas chromatography indicated over 150 components. Most of the major components have been identified. These include alcohols, esters, acetals, aldehydes, furfural, methyl furfural, aromatic aldehydes, ketones, and esters, a few terpenes, and a few aromatic hydrocarbons. The strength of this technique is shown by the determination of several compounds in one sharp chromatographic peak. On the other hand certain prominent species could not bbe identified by the low resolution (resolution about 200) mass spectral data obtained.
