“…However, there are no literature reports in which this test was performed on the EOs of E. alba , E. eugenioides , E. fasciculosa and E. stoatei . Only the paper of Cahaya and coworkers [ 76 ] reported the antioxidant activity of an EO of E. robusta , with a weaker activity in comparison to that of our sample.…”

Eucalyptus species have been widely employed in the projects of reforestation in Tunisia. Although their ecological functions are controversial, these plants are indeed important to counteract soil erosion, and represent a fast-growing source of fuelwood and charcoal wood. In the present study, we considered five Eucalyptus species, namely Eucalyptus alba, E. eugenioides, E. fasciculosa, E. robusta, and E. stoatei cultivated in the Tunisian Arboreta. The aim was to carry out the micromorphological and anatomical characterization of the leaves, the extraction and phytochemical profile of the essential oils (EOs), and the evaluation of their biological properties. Four of the EOs showed the prevalence of eucalyptol (1,8-cineole) varying from 64.4 to 95.9%, whereas a-pinene predominated in E. alba EO (54.1%). These EOs showed in vitro antioxidant activity, and reduced the oxidative cellular stress as shown by their activity on reactive oxygen species (ROS) production, and modulation of the expression of antioxidant enzymes, such as glutamate-cysteine ligase (GCL) and heme oxygenase-1 (Hmox-1). Moreover, the EOs inhibited the production of nitric oxide (NO), showing anti-inflammatory activity. The data collected suggest that these EOs may be considered a promising therapeutic strategy for inflammation-based diseases and may represent an additional value for the economy of Tunisia.

The application of biopesticides is one of the safest alternatives to realize organic agriculture that does not cause harmful impacts to both consumers and the environment. This activity aims to apply biopesticides in eradicating fruit flies (Bactrocera sp.) on Sweet Orange (Citrus X Sinensis) plants. The partner location is the Bukit Rumah Sendi Farmers Group in Karo Regency. Eucalyptus grandis leaves were extracted using steam distillation then the concentration of 1,8 Sineol was determined using GCMS and the concentration was 52%. Eucalyptus oil was mixed with kerosene and detergent then determined the LC50 value in fruit flies and observed for 24, 48, 72, and 96 hours and produced an LC50 value of 35%. This shows that biopesticides are quite effective in eradicating fruit flies.
