We reported the  in vitro  anti-HIV-1 activity, cytotoxicity, cytokines expression and chemical profile of  Anadenanthera colubrina . Cytotoxicity was evaluated on TZM-bl, HL2/3 cells and macrophages. Anti-HIV-1 activity was determined by Luciferase assay (TZM-bl cells) and by HIV-p24 quantification (macrophages) assessed by ELISA. TZM-bl and HL2/3 cells were used to determine cell-cell fusion inhibition. Cytokines expression was assessed by ELISA. Chemical composition was determined by Gas Chromatography Coupled to Mass Spectrometry. At 66.6 µg/mL, the extract maintained the cell viability above 90%. At 33.28 µg/mL, the extract reduced 82.8% of HIV-1 infection (TZM-bl cells) and HIV-p24 expression (macrophages). The extract inhibited approximately 70% of TZM-bl and HL2/3 cells fusion. Extract did’t induce inflammatory response. Phytochemical analysis showed presence of flavonoid, phenolic acids, fatty acids and sugars. This is the first  s tudy presenting the anti-HIV effect of  A. colubrina , showing low cytotoxicity and no inflammatory stimuli, important requirements for a microbicide development.
