[Poster].h[electronic resource]  aIn: International Mass Spectrometry Conference, 22., August 26-31,  FLORENCE, ITALYc2018  aMaytenus ilicifolia is an important folk medicinal plant, largely found in Paraguay, Uruguay, Argentina, and Brazil. Contributions to human health have been reported [1-3]. A purified fraction from the ethanol extract of Maytenus ilicifolia leaves antiparasitic activity against gastrointestinal nematodes (GIN) of cattle. The aim of the present study was to perform a preliminary structural characterization of this bioactive fraction by LC-ESI-IT-MSn, and to test the in vitro anthelmintic activity against cattle GIN.  aOVINOS  aPARASITOS  aGASTROINTESTINAL NEMATODES  aSHEEP1 aDE SOUZA, G.1 aMEDEROS, A.1 aOLIVARO, C.
