Direct analysis of Peucedanum palustre samples by desorption atmospheric pressure photoionization-mass spectrometry

•DAPPI-MS could identify the main coumarin products in dried P. palustre.•DAPPI-MS required no sample preparation or chromatographic separation.•The analysis of plant samples by DAPPI-MS takes only seconds.•Different ions and ionization routes were observed with toluene and acetone dopants.•Similar compounds were detected from P. palustre samples with DAPPI-MS and LC–MS.
