Weed control in sustainable agriculture requires new bioherbicidal molecules to replace synthetic herbicides that have damaged the environment and generated resistance in weeds. This study was conducted to investigate the chemical composition of Eucalyptus globulus essential oil and to explore its bioherbicidal potential on the germination and radicle growth inhibition. The phytotoxic effects of E. globulus essential oil (1, 10 and 20 μL mL-1) were tested in comparison to those of the synthetic herbicide Glyphosate (1, 10 and 20 μL mL-1) in bioassays of germination and radicle growth of Lactuca sativa and the resistant weeds Avena fatua and Amaranthus hybridus. Gas Chromatography with Flame Ionization Detector and Gas Chromatography-Mass Spectroscopy analysis showed that major monoterpenes comprised 1,8-Cineole (86.94%), α-pinene (7.71%), d-limonene (2.65%), and p-cymene (1.48%). The seed germination and radicle length exhibited different degrees of inhibition in response to the concentration of E. globulus essential oil. At some concentrations, both the Glyphosate herbicide and the E. globulus essential oil demonstrated the same phytotoxicity against the resistant weeds A. fatua and A. hybridus. Essential oil bioactivity Lethal Concentration (LC50) in the majority of cases was lowest for A. hybridus, followed by A. fatua and L. sativa. Based on the results, it can be concluded that E. globulus essential oil possesses phytotoxic potential and could be explored as a bioherbicide for resistant weeds management programs.

Essential oil was obtained in a yield 1.1%, w/w, by steam distillation of Elionurus tristis leaves from Madagascar. The chemical composition was analyzed qualitatively and quantitatively by GC-MS and GC-FID, respectively. To the best of our knowledge, this is the first chemical analysis of this essential oil. Seventy-three compounds were identified, corresponding to 94.9% of the total essential oil. The principal compounds were sesquiterpenes and the more represented were β-gurjunene (18.4%), neoclovene (15.8%) and nootkatone (10.4%). Through a comparative study, we observed a large variability between the components of E. tristis essential oil and those from others species of the same genus. Evaluation of the antioxidant (ABTS and DPPH assays) and anti-tuberculosis activities of the essential oil showed weak antioxidant potency but an interesting anti-tuberculosis activity with a MIC of 32 mg/L. This activity prompted us to evaluate individually the major components for the treatment of tuberculosis.

Artabotrys species which belongs to Annonaceae family are pleasant smelling and it is attributed to the presence of mono and sesquiterpenoids present in the essential oil of the plant. The objective of the present work is to review the chemical composition of the essential oils reported from twenty different Artabotrys species from various parts of the world. In the various Artabotrys species, the major compounds are monoterpene and sesquiterpene hydrocarbons and oxygenated sesquiterpenes.  The frequently and most commonly identified constituents are β-caryophyllene, caryophyllene oxide, 3-Carene, cyperene, cyperenone and 1,5-epoxy-salvial4(14)-ene.  Other constituents seems to be more specific to the respective Artabotrys species.

Insecticidal activity of essential oil extracted fromMorinda lucidawas tested on pulse beetleCallosobruchus maculatus, which is a pest that causes serious damage to several pulses. The insecticidal activity was compared with two pesticides, Phostoxin and Primo-ban-20. 120 mixed sex adultC. maculatuswere introduced, along with 30 g of cowpeas. Four concentrations (0.40, 0.20, 0.10, and 0.05 μg/mL) of theM. lucidaessential oil, Phostoxin, and Primo-ban-20 were tested. Essential oil chemical composition was analyzed by GC-MS.M. lucidaessential oil showed a high toxicological effect, producing 100% mortality after 72 hours at a dose of 0.20 μg/mL.M. lucidaessential oil had a potent insecticidal activity (LC90= 0.629 μg/mL) compared to both pesticides, Phostoxin (LC90= 0.652 μg/mL) and Primo-ban-20 (LC90= 0.726 μg/mL), at 24 h. The main compounds of the essential oil were the oxygenated monoterpenoids, 1,8-cineole (43.4%), andα-terpinyl acetate (14.5%), and the monoterpene hydrocarbons, mostly sabinene (8.2%) andβ-pinene (4.0%). Results clearly indicate thatM. lucidaessential oil can be used as an effective alternative for pulse beetleC. maculatuscontrol, and it could be tested against other pulse beetles affecting Asia and Africa and throughout the world, thereby reducing use of synthetic pesticides.
