title: Dehydrodimers of caffeic acid in the cell walls of suspension-cultured Mentha.
abstract: Dehydrodicaffeic acid derivatives were found in the cell walls of suspension-cultured cells of Mentha. Using gas chromatography/mass spectrometry (GC-MS) in a single ion chromatography at m/z 790 and m/z 718, eleven peaks of trimethylsilylated dehydrodimers of caffeic acid were detected in the extracts from the cell walls of suspension-cultured cells of Mentha using sodium hydroxide. The result suggests that dehydrodicaffeates are formed in the cell walls from two molecules of caffeate, probably formed through C-C, and C-O-C coupling processes.
