This work describes the evaluation of the in vitro cytotoxic activity and bioactivity guided fractionation of the extracts in hexane and CH2Cl2 of Porcelia macrocarpa seeds. In order to do this, extracts in hexane and CH2Cl2 were prepared and submitted to evaluation of the cytotoxic potential against B16F10Nex2 cell line (murine melanoma). As the CH2Cl2 extract displayed activity (cell viability 45±3% to 50 ?g/mL and 34±2% to 25 ?g/mL) it was fractionated on silica gel, resulting in a mixture of two acetylenic acetogenins which were purified using HPLC procedures. Analysis of 1H NMR spectra and 13C, as well as MS allowed the identification of 2-(eicos-11-yn-19-enyl)-3-hydroxy-4-methyl-?-lactone (I) and 2-(eicos-11-ynyl)-3-hydroxy-4-metil-? ...
