Plukenetia volubilis  Linneo, or Sacha inca, is an oleaginous plant from the Euphorbiaceae family. The aim of this work was to perform a chemical and biological analysis of different leaf extracts from  P. volubilis  such as aqueous extract (AEL), methanol (MEL), ethanol (EEL), chloroform (CEL), and hexane (HEL). Thin layer chromatography analysis revealed the presence of phenolic compounds, steroids, and/or terpenoídes. Furthermore, the antioxidant activities were analyzed by  in vitro  assays and their effects on cell lineages by  in vivo  assays. The Total Antioxidant Capacity (TCA) was expressed as equivalent ascorbic acid (EEA/g) and it was observed that the extracts showed values ranging from 59.31 to 97.76 EAA/g. Furthermore, the DPPH assay values ranged from 62.8% to 88.3%. The cell viability assay showed that the extracts were able to reduce viability from cancer cells such as HeLa and A549 cells. The extracts MEL and HEL (250  µ g/mL) were able to reduce the proliferation of HeLa cells up to 54.3% and 48.5%, respectively. The flow cytometer results showed that these extracts induce cell death via the apoptosis pathway. On the other hand, the extracts HEL and AEL were able to induce cell proliferation of normal fibroblast 3T3 cells.
