Although extracts and consumed foods from Physalis species contain sucrose esters from their glandular trichomes, there is no experimental data available on their toxicological effects. As peruvioses A and B isolated from Physalis peruviana L. calyces have proved to be effective anti-inflammatory and immunomodulatory compounds, this work aimed to investigate their sub-acute toxicity study and genotoxicity. For this, CD-1(ICR) mice were treated intraperitoneally with peruvioses at doses of 2.5, 5, and 10mg/kg/day for 28 consecutive days, to simulate therapeutic and over-therapeutic dosage levels. At the end of the treatment, animals were sacrificed and their organs weighted, and blood and tissue samples were collected. Toxicological endpoints included clinical signs; food consumption; body and organ weights; hematological and biochemical parameters; as well as macroscopic and microscopic examination of tissues. The results showed no significant differences between treated animals and control group at macroscopic, histological, molecular, and biochemical levels. In addition, a combination of mammalian erythrocyte micronucleus test, comet assay in peripheral blood cells, and Ames test, did not reveal genotoxic effects induced by peruvioses. Taken together, our data suggests that peruvioses A and B can be safely employed to treat inflammatory diseases.
