ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Croton argyrophyllus Kunth., commonly known as "marmeleiro" or "cassetinga," is widely distributed in the Brazilian Northeast region. Its leaves and flowers are used in traditional medicine as tranquilizers to treat flu and headaches. AIM OF THE STUDY: This study was conducted to determine the chemical composition and toxicological safety of essential oil from C. argyrophyllus leaves using in vitro and in vivo models. MATERIALS AND METHODS: The chemical composition of the essential oil was determined using a gas chromatograph coupled to a mass spectrometer. Cytotoxicity was tested in the HeLa, HT-29, and MCF-7 cell lines derived from human cells (Homo sapiens) and Vero cell lines derived from monkeys (Cercopithecus aethiops) using the MTT method. Acute toxicity, genotoxicity. Mutagenicity tests were performed in Swiss mice (Mus musculus), which were administered essential oil orally in a single dose of 2000 mg/kg by gavage. RESULTS: The main components of the essential oil were p-mentha-2-en-1-ol, α-terpineol, ß-caryophyllene, and ß-elemene. The essential oil exhibited more than 90% cytotoxicity in all cell lines tested. No deaths or behavioral, hematological, or biochemical changes were observed in mice, revealing no acute toxicity. In genotoxic and mutagenic analyses, there was no increase in micronuclei in polychromatic erythrocytes or in the damage and index in the comet assay. CONCLUSIONS: The essential oil was cytotoxic towards the tested cell lines but did not exert toxic effects or promote DNA damage when administered orally at a single dose of 2000 mg/kg in mice.
