This study aimed to evaluate the insecticidal and repellent effects of tea tree, Melaleuca alternifolia (Myrtales: Myrtaceae), and andiroba, Carapa guianensis (Sapindales: Meliaceae), essential oils on two species of fly. For in vitro studies, free-living adult flies were captured and reared in the laboratory. To evaluate the insecticidal effects of the oils, adult flies of Haematobia irritans (L.) and Musca domestica L. (both: Diptera: Muscidae) were separated by species in test cages (n = 10 per group), and subsequently tested with oils at concentrations of 1.0% and 5.0% using a negative control to validate the test. Both oils showed insecticidal activity. Tea tree oil at a concentration of 5.0% was able to kill M. domestica with 100.0% efficacy after 12 h of exposure. However, the effectiveness of andiroba oil at a concentration of 5.0% was only 67.0%. The insecticidal efficacy (100.0%) of both oils against H. irritans was observed at both concentrations for up to 4 h. The repellency effects of the oils at concentrations of 5.0% were tested in vivo on Holstein cows naturally infested by H. irritans. Both oils demonstrated repellency at 24 h, when the numbers of flies on cows treated with tea tree and andiroba oil were 61.6% and 57.7%, respectively, lower than the number of flies on control animals. It is possible to conclude that these essential oils have insecticidal and repellent effects against the species of fly used in this study.

“…Studies conducted by Boligon et al [6] demonstrated that the major constituent in the essential oil of T. catharinensis leaves was β-caryophyllene (56.9%) having anti-inflammatory, antibiotic, antioxidant, anticarcinogenic and local anesthetic activities. Here we report the identification and quantitation of phenolic compounds, for the first time, by HPLC/DAD in the crude extract and fractions of T. catharinensis stem bark.…”

In this study we evaluated the composition of the crude extract and fractions of Tabernaemontana catharinensis (Apocynaceae) by HPLC/DAD and GC/MS. We also tested the antioxidant capacity and investigated the contents of polyphenols, flavonoids, tannins and alkaloids of T. catharinensis stem bark. The extract and fractions showed inhibition against thiobarbituric acid reactive species (TBARS), in the following order: ethyl acetate (IC 50 = 4.7 ± 0.2 μg/mL) > dichloromethane (23.9 ± 1.1 μg/mL) > n-butanolic (25.2 ± 0.4 μg/mL) > crude extract (38.0 ± 0.07 μg/mL). Moreover, the DPPH assay, presented IC 50 values ranged from 5.6 ± 0.6 to 30.3 ± 1.3 μg/mL. Contents of total phenols, flavonoids, tannins and alkaloids of T. catharinensis followed the order: ethyl acetate > n-butanolic > dichloromethane fractions > crude extract. HPLC/DAD analyses indicated that gallic, chlorogenic and caffeic acids, and rutin, quercetin and kaempferol are components of the species. Taken together, the results suggest that T. catharinensis could be considered an effective agent in the prevention of diseases associated with oxidative stress.

The antioxidant capacity of the crude extract and fractions of Tabernaemontana catharinensis fruits and branches, was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the content of polyphenols, flavonoids, alkaloids and condensed tannins were determined by the spectrophotometric method. The ethyl acetate fraction of the fruits and the n-butanol fraction of the branches showed IC 50 of 181.82 µg/mL and 78.19 µg/mL, respectively. All fractions were analyzed by high performance liquid chromatography (HPLC), in the branches were quantified chlorogenic acid in the chloroform (8.96 mg/g), ethyl acetate (4.31 mg/g) and n-butanol (3.33 mg/g) fractions; caffeic acid in the ethyl acetate (5.24 mg/g) and n-butanol (1.81 mg/g); gallic acid (0.52 mg/g) in the n-butanol. In the fruits, chlorogenic acid in the chloroform (1.67 mg/g); rutin in the ethyl acetate (3.45 mg/g) and n-butanol (8.98 mg/g) fractions.The present study showed that these quantified compounds can contribute to antioxidant capacity which was higher in the branches than in the fruits.
