Abstract

Abstract: This work aimed to analyze the chemical composition of the essential oils from Psidium laruotteanum Cambess. (Marangaba-peluda), Psidium salutare (Kunth) O. Berg (Marangaba-vermelha) and Psidium sobralianum Landrum & Proença (Araçá-de-veado), and to investigate their antibacterial and antioxidant activities. Twenty-six chemical compounds were identified, with a predominance of hydrocarbon sesquiterpenes (38.46%). The essential oils presented different compounds, with the majorities being Viridiflorol (27.89%), α-caryophyllene (27.62%) and Isocaryophyllene (10.16%) for P. laruotteanum ; 1, 8-Cineole (57.07%) and α-phellandrene (14.62%) for P. salutare and α-pinene (11.78%), Viridiflorol (11.64%), δ-amorphene (9.93%) and γ-eudesmol (9.44%) for P. sobralianum . The essential oil of P. laruotteanum showed the best antibacterial results, inhibiting the growth of E. coli at concentration 96 μg/mL, and demonstrating synergistic effect when associated with amikacin on S. aureus, with p < 0.001. The dominance of Caryophyllene derivatives may be responsible for the activity. P. salutare and P. sobralianum, were only able to inhibit bacterial growth at higher concentrations, between 341.33 μg/mL and ≥1024 μg/mL. Regarding antioxidant activity, the three species were able to inhibit DPPH in a concentration-dependent manner, with the best result for P. sobralianum oil with IC50 of 5.99 mg/mL.
