    The plant species Lepechinia meyenii (Walp.) Epling (commonly known as salvia, pacha salvia, salvia de puna, kotapuriña) is a native plant that grows in the southern Andean regions of Peru (Ayacucho, Huancavelica, Cuzco, and Puno). The main objective of the present study was to conduct a phytochemical evaluation and determine the antimicrobial activity of the essential oil obtained from the aerial parts of Lepechinia meyenii (Walp.) Epling “pacha salvia.” In the methodology, a gas chromatograph coupled with a mass spectrometer (GC-MS) was employed to determine the phytochemical composition, and the agar diffusion method (Kirby-Bauer) was used to evaluate antimicrobial activity. The results showed the presence of 31 components, with the major compounds being α-pinene (21.37%), eucalyptol (1,8-cineole = 18.80%), and D-limonene (15.43%). The essential oil demonstrated antimicrobial activity against Staphylococcus aureus ATCC 6538 when compared with gentamicin 10 µg. It is concluded that the essential oil from the aerial parts of Lepechinia meyenii (Walp.) Epling “pacha salvia” contains active components with antimicrobial activity.
