Hydrodistillation of essential oil of muña (Minthostachys mollis) and huacatay (Tagetes minuta) using ultrasound as pretreatment Essential oils (EO) are being studied against various diseases replacing drug treatments, which are intended to be used as a health solution using medicinal plants. Muña and huacatay are two plants that are investigated for their healing, antifungal, antimycotic properties against stomach and bronchial diseases, among others. The present research was carried out with the objective of extracting the essential oil of muña and huacatay by hydrodistillation, applying ultrasound (US) as a pretreatment, to try to improve the extraction process of the EOs. The muña plants were purchased from the market in the city of Tingo Maria coming from the city of Huanuco and the huacatay plants were purchased from market N°2 in the city of Tarapoto coming from the district of San Roque, Lamas. The research had a duration of 6 months. For the extraction of muña and huacatay EO, ultrasound was used as pretreatment at ultrasound power (50% and 75%) and ultrasound time (2 and 4 minutes), then the extraction process was carried out by hydrodistillation; muña was extracted at 60 minutes and huacatay at 35 minutes. Extraction yields were obtained in both essential oils, with no significant difference between the tests. In muña, the highest yield was obtained in the 2 min 50% US test (1.24 ± 0.02%), and in huacatay the highest yield was obtained in the 2 min 50% US test (0.41 ± 0.04%). The results for the Total Phenol content indicated that they were statistically different, reaching higher values with the 4 min 75% US test for muña (12.75 ± 1.40 mg EAG/ mL AE) and the Control test for huacatay (31.04 ± 0.80 mg EAG/ mL AE). Regarding the antimicrobial activity of both the muña and huacatay EO, they proved to have high inhibitory activity against the strains tested, but they did not overcome the positive controls. Eleven possible chemical compounds were found in the essential oil of muña, the major compounds being L-menthone (27.15%), isovaleraldehyde (16.76%), and isomenthone (11.03%) and in the essential oil of huacatay 10 possible compounds, the major compounds being cis-tagetone (37.06%), γ-tetradecalactone (17.39%) and Photocitral B (9.70%).
