--- Objective: To determine the antioxidant and citotoxic activity of the physalins and flavonoids Physalis peruviana L leaves. Design: Experimental. Setting: Faculty of Pharmacy and Biochemistry and Faculty of Biology, San Marcos Major National University; Laboratory of Research and Development “Abraham Vaisberg Wolach”, Cayetano Heredia Peruvian University. Materiales: Physalins and flavonoids of Physalis peruviana L leaves; embryos Tetrapygus niger; human tumoral cells lines H-460, HuTu80, DU145, MCF-7, M-14, HT-29, K562 and 3T3 fibroblasts. Interventions: Antioxidant activity was determined with DPPH radical scavenging method and cytotoxic activity was observed by black sea urchin bioassay and tumoral cells lines. Main outcome measures: Antioxidant and cytotoxic activities. Results: we found the percentages of radical-scavenging DPPH were 95,0% and 26,6% for physalins and flavonoids respectively; physalins and flavonoids showed cytotoxic activity starting from concentration of 10 ppm on black sea urchin bioassay; we found the percentage of cellular growth for every dilution in ever cellular line, the inhibiting concentration of average growth for each cellular line from physalins was 1.53, 0.54, 1.75, 0.63, 0.45, 0.48, 0.28 y 0.57 µg/mL, the inhibiting concentration with flavonoids was 62.24, 22.35, 86.77, 45.08, 25.32, 25.01, 21.68 y 15.93 µg/mL for H-460, HuTu80, DU145, MCF-7, M-14, HT-29, K562 and 3T3, respectively; the physalins and flavonoids selectivity index were between 0.16 to 17.32 and 345.27 to 1382.02, respectively. Conclusions: The Physalis peruviana leaves physalins showed lower antioxidant activity than flavonoids on DPPH radical scavenging method; the physalins showed greater citotoxic activity tan flavonoids on black sea urchin bioassay and cell lines in vitro. Key words: Physalins, flavonoids, Physalis peruviana L., antioxidant activity, citotoxic activity.
