Abstract:
Context: Aedes albopictus is a vector of dangerous diseases such as dengue and Zika, requires effective repellents. Objectives: This study investigates the potential of Syzygium aromaticum essential oils as an antioxidant agent and their efficacy in repelling against A. albopictus. Methods: Hydro distillation and GC and GCMS, DPPH, FRAP. In vivo test used Azman Kamal rats. Results: The essential oils of S. aromaticum comprised of eugenol (79.12%), -caryophyllene (11.60%) and (Z)-Isoeugenol acetate (5.56%) as their major constituents. It also has a high antioxidant effect, with the DPPH test showed 80% inhibition and the FRAP test displayed a value of 300 μmol Fe2+ per mg of extract. In addition, the mosquito-repellent test showed that S. aromaticum EO has a 100% mosquito-repellent effect. Conclusion: S. aromaticum was found to be an effective antioxidant repellent against A. albopictus mosquitoes.
