   • Selon Kato da Silva B (2021)

     Extrait The aim of this study was to evaluate the Porophyllum ruderale effects on the liver in murine melanoma model B16-F10 & to determine the antioxidant potential. Although a significant antioxidant activity was verified for the two concentrations analyzed, they were not sufficient to minimize the melanoma effects toxic in the mice liver as observed by histological changes & that leads us to conclude that the hydroalcoholic extract of aerial parts of PR, in the concentrations used, possesses antioxidant properties, good performance in inhibiting the proliferation of human melanoma cells, but it has no hepatoprotective effect in the melanoma cutaneous treatment,.

   • Selon Conde-Hernandez LA (2014)

     Extrait Extracts from fresh and dried samples of Mexican pepper leaf (Piper auritum Kunth) & “papalo” (Porophyllum ruderale) were obtained using a stirring or an ultrasound extraction system with five types of solvents (water, 50:50% v/v ethanol: water, 70:30% v/v ethanol: water, 85:15% v/v ethanol:1.5 N HCl, & ethanol). Total phenolic compounds and antioxidant activity were evaluated with the phenol Folin Ciocalteu reagent and the ABTS method, respectively.

   • Selon Condé-Hernandez LA (2017)

     Extrait Essential oils (EO) of Piper auritum (“hoja santa”) & Porophyllum ruderale (“pápalo” or “pápalo quelite”), previously dried, were obtained by supercritical extraction (SCE) with CO2. P auritum oil yields were in the range 2.37 ± 0.05–3.09 ± 0.12 g oil/100 g dry material & in P ruderale the yields were 0.82 ± 0.01–1.35 ± 0.09 g oil/100 g dry material.

   • Selon Lima G (2011)

     Excerpt The present work investigated the antinociceptive & antiinflammatory activities of the Porophyllum ruderale aqueous extract (PRAE). Taken together, our results suggest that the PRAE can constitute target potential for use in thérapies of the pain & inflammation.

   • Selon Raggi L (2014)

     Excerpt Porophyllum ruderale (Asteraceae), known as “arnica paulistana”, is used for wound healing, antimicrobial and anti-inflammatory. The present work aims to compare the chemical composition of essential oils from both Porophyllum ruderale subspecies cultivated in two biogeographically different regions, Brazilian Cerrado (Mogi-Guaçu, São Paulo) and Atlantic Rain Forest (Instituto de Botânica, São Paulo) in different phenological stages.
