Antibacterial activity, chemical composition, and cytotoxicity of leaf's essential oil from Brazilian pepper tree (Schinus terebinthifolius, Raddi)

Abstract

The antibacterial potential of leaf's essential oil (EO) from Brazilian pepper tree (Schinus terebinthifolius Raddi) against staphylococcal isolates from dogs with otitis externa was evaluated. The minimum inhibitory concentration of EO ranged from 78.1 to 1,250 g/mL. The oil was analyzed by GC and GC/MS and cytotoxicity tests were carried out with laboratory animals. The veterinary use of essential oils depends on clinical

Schinus terebinthifolius Raddi ( Aroeira) leaves oil attenuates inflammatory responses in cutaneous wound healing in mice

“…The oil was stored in amber glass container, tightly closed kept in freezer, until the experiment, at a temperature of -20°C. The study of the leaves oil had its chemical profile reported by Silva et al 16 , which identified thirty-three components, representing 95.5% of the oil. Among the majority of this oil compounds are p-Cymen-7-ol (22.5%), 9-epi-(E)-cariophyllene (10.1%), carvone (7.5%) and Verbenone (7.4%).…”

USE OF HYDROALCOHOLIC EXTRACT OF Schinus terebinthifolius Raddi IN PRE- AND POST-MILKING ANTISEPSIS OF THE TEAT IN DAIRY COWS

“…(1) We can state that the leaves of Schinus terebinthifolius Raddi can be used for antisepsis in milking because the incidence of NIMI was similar for both treatments. Silva, (21) in an in vitro study, reported the antibacterial action of the essential oil from leaves of this plant against Staphylococcus spp. coagulase positive isolated from external otitis in dogs.…”

“…On the other hand, after repeated milking, the teatend tissue shows changes that appear as a crown around the teat orifice, such changes may result from mechanical forces exerted by the vacuum during milking. (11) Silva (21) performed toxicological tests of the essential oil from the leaves of Schinus terebnthifolius Raddi in laboratory animals and observed no changes.…”

Mast cell concentration and skin wound contraction in rats treated with Brazilian pepper essential oil (Schinus terebinthifolius Raddi)

“…Regarding in vitro use, Silva et al 19 observed favourable effects during the treatment of canine otitis with Schinus terebenthifolius Raddi essential oil.…”
