    A phytochemical and toxicological study of the hydroalcoholic extract of fresh leaves of Tanacetum vulgare L. (“Palma real”) was carried out. The species was collected in the district of Tamburco, Province of Abancay, Department of Apurímac. A hydroalcoholic extraction of the fresh leaves was performed. Through solubility tests and phytochemical analysis, it was determined that the extract is soluble in polar solvents and contains primary metabolites such as carbohydrates and free amino groups, as well as secondary metabolites including alkaloids, steroids, flavonoids, and phenolic compounds. Alkaloids were extracted using an alkaline medium; a fraction (F1) was identified by thin-layer chromatography, employing a MeOH-CHCl₃ solvent system (1:1.5 v/v), and subsequently isolated by preparative chromatography. A possible chemical structure was identified through ultraviolet-visible and infrared spectroscopic analyses, revealing amino, carbonyl, and aromatic groups. For the toxicological study, the Betancourt method was applied, using an acute toxicity model with a limit dose of 2000 mg/kg in Mus musculus Balb/C-53 mice. Histopathological sections of perfused organs showed damage to the liver and kidney. Very mild toxicity was observed in the stomach, while the lung preserved its histopathological structure.
