    The plant species Schkuhria pinnata (Lanm.) Kuntze ex Thell, “Canchalagua,” from the city of Ayacucho, was obtained at the Wholesale Market “La Parada,” district of La Victoria – Lima, and was subsequently taxonomically classified at the Natural History Museum of the Universidad de San Marcos. The sample was cleaned and dried at the Research Center of the Universidad Norbert Wiener, where the parts of the plant—stem, root, leaves, and flowers—were separated. Hydroalcoholic extracts of each part were prepared, and the phytoconstituents present were identified, such as flavonoids, reducing sugars, phenolic compounds, and carbohydrates. For the microbiological test, the Disk Diffusion method was used with blood agar medium and the Propionibacterium acnes strain (ATCC® 11827). Standard antibiotics Q.P.: Doxycycline, Levofloxacin, Azithromycin, and Penicillin were employed. Disks impregnated with 10 µL of the hydroalcoholic extracts were added and compared with the standard antibiotic disks on the plates, showing that the hydroalcoholic extract of the leaves presented the largest inhibition halo diameter.
