health-promoting compounds, is presented in this work. A comprehensive characterization
of P. peruviana calyx extracts, obtained by an optimized pressurized liquid extraction (PLE)
procedure, is developed applying first an ultra-high-performance liquid chromatography
coupled to quadrupole time-of-flight tandem mass spectrometry (UPLC-ESI-q-TOF-MS/MS)
method in positive and negative electrospray ionization (ESI) mode. A total of fifty-six …
