Academic Editors: Valeria Patricia Sülsen and Albertina Moglioni Received: 3 April 2019; Accepted: 22 April 2019; Published: 24 April 2019 Abstract: Essential oils (EOs) have gained increasing attention due to their pharmacological effectiveness, and they also constitute some of the most popular natural products. In this study, we present the chemical characterization of the EO from Phania matricarioides and the in vitro activity/selectivity against a wide panel of bacteria, fungi and parasitic protozoa. Forty-five compounds were identified in the studied EO, of which lavandulyl acetate (40.1%) and thymyl isobutyrate (13.9%) were the major components. The EO did not inhibit bacterial or fungal growth at the maximum concentration tested (64 µg/mL), although it displayed activity on all evaluated protozoa (IC50 values ranging from 2.2 to 56.6 µg/mL). In parallel, the EO demonstrated a noteworthy cytotoxic activity against peritoneal macrophages (CC50 values of 28.0 µg/mL). The most sensitive microorganism was Trypanosoma cruzi, which had a superior activity (IC50 = 2.2 µg/mL) and selectivity (SI = 13) in respect to other parasitic protozoa and the reference drug (p < 0.05). Further in vivo studies are needed to evaluate the potential use of this EO and the main compounds as antitrypanosomal agents. To our knowledge, this is the first report of chemical characterization and antimicrobial assessment of the EO from P. matricarioides. Keywords: Phania matricarioides; essential oil; antimicrobial screening; cytotoxicity; Trypanosoma cruzi 1. Introduction Indiscriminate and irrational use of antimicrobial agents has created an unprecedented challenge for human civilization due to the microbes’ development of antimicrobial resistance. Complementary and alternative medicines (CAMs) are used by 60–80% of developing countries, as they are one of the most prevalent sources of medicine worldwide. In recent years, research on plant-based drugs has increased tremendously, and there is some hope seen in certain medicinal plants that have immense potential to combat bacterial, fungal, protozoal and viral diseases with Molecules 2019, 24, 1615; doi:10.3390/molecules24081615 www.mdpi.com/journal/molecules Molecules 2019, 24, x FOR PEER REVIEW 2 of 11 plant-based drugs has increased tremendously, and there is some hope seen in certain medicinal Moleculesplants that2019 ,have24, 1615 immense potential to combat bacterial, fungal, protozoal and viral diseases 2with of 11 safety.
