Abstract

Using gas chromatography/mass spectrometry we have observed six peaksin the single ion chromatograph at mit 674 of the alkaline extract ofbarley straw cell walls. The breakdown pattern of these ions suggeststhat they could all be isomers of 5,5'-bis-dehydroferulic acid. Sinceonly the 5, 5' linkage is reported to be present in plants this tentatively suggests that these compounds exhibit stable orientational isomerism about this bond. Plausible breakdown mechanisms are presented which allow for the complete assignment of structure to all the isomers. These mechanisms suggest that the two pairs of breakdown ions at m/z 556 and 467, and 265 and 193 are representative of trans and cis double bonds, respectively.
