Quantitative and structural analysis of amides and lignans in Zanthoxylum armatum by UPLC-DAD-ESI-QTOF–MS/MS.

Highlights: [•] Rapid and simultaneous quantification of lignans and amides is achieved by UPLC-DAD. [•] Different plant parts (leaves, bark, seeds) showed significant variation. [•] Tandem UPLC-DAD-ESI–MS/MS led to characterization of sixteen compounds. [•] Structural analysis by MS/MS and UV spectra is also discussed. [Copyright &y& Elsevier]
