“Aroeira” (Myracrodruon urundeuva) methanol extract: the relationship between chemical compounds and cellular effects
2016
AbstractContext: “Aroeira” [Myracrodruon urundeuva Allemao (Anacardiaceae)] is a tree whose leaves have been studied for therapeutic purposes in medicine and dentistry.Objective: The study chemically identifies the leaf extract of aroeira and determines its effect on human gingival fibroblasts.Materials and methods: An 80% methanol leave extract was obtained by maceration and chemically identified through flow-injection analysis–electrospray ionization–ion trap–tandem mass spectrometry (FIA–ESI–IT–MSn). Cytotoxicity of the aroeira’s methanol extract was evaluated in lineage of fibroblasts. Adherent cells were treated with different concentrations of aroeira’s methanol extract in the medium: 0.1, 1, 10, 100 and 1000 μg/mL. Control cells were cultivated in the medium only. Analyses were done at 24, 48, 72 and 96 h of culture by neutral red assay; and at 24, 48 and 96 h by crystal violet assay.Results: FIA–ESI–IT–MS analysis determined the presence of compounds, for the first time in the species: quercetin-O...
