    Currently, many studies are being conducted on different medicinal plant species, as a large part of the population in various communities relies on traditional medicine to address health problems. The objective of this study was to determine the chemical constituents present in the hydroalcoholic extract of Calceolaria rhaccodes Krazl “calceolaria” (commonly known as Venus slipper, little shoe, capachito, virgin’s shoe, or calceolaria) and to evaluate its antioxidant activity. The species was collected in March 2013 in the district of Ayavi, Huaytara province, Huancavelica, at 3600 m a.s.l. Fresh flowers were macerated in hydroalcoholic solution, and phytochemical analysis revealed the presence of flavonoids, alkaloids, tannins, quinones, carbohydrates, and reducing sugars. Thin-layer chromatography (TLC) was performed with the solvent system BuOH:CH₃COOH:H₂O (4:1:5 v/v/v). Antioxidant activity was evaluated using the DPPH method. The results confirmed that the hydroalcoholic extract of Calceolaria rhaccodes flowers contains important bioactive secondary metabolites and presents antioxidant activity, highlighting its potential as a source of natural therapeutic agents.
