Gas chromatography mass spectrometry based profiling of alkyl coumarates and ferulates in two species of cattail (Typha domingensis P., and Typha latifolia L.)

摘要: Abstract Several long-chain n-alkyl coumarates and ferulates were identified in cattails (Typha domingensis Typha latifolia) from the Florida Everglades. Characterization of these compounds was achieved based on interpretation mass spectra obtained by GCMS as their trimethylsilyl ether derivatives, comparison with published available standards. Both p-coumarates roots leaves both species, featuring unique distribution patterns differences between leaf root biomass. For have higher concentrations a much greater diversity but different side chain carbon numbers ranging C14 to C28. only contained traces p-coumarates, while types present latifolia material. These chemicals not found other dominant wetland vegetation, which suggests potential for application phytochemical tracers fresh cattail-derived organic matter Everglades ecosystem.
