For their pungency and tanginess, ginger rhizomes (Zingiber officinale) are often used in cooking. Ginger has long been used in traditional medicine and home remedies to treat pain and inflammation. This research tests Z. officinale (EOZ) essential oils' chemical composition, insecticidal, and antioxidant properties in vitro and in silico. EOZ yielded 0.69% of root mass with 23 chemicals. The main chemicals in EOZ were α-zingiberene (23.850%), Geranial (14.160%), and (E,E)-α-farnesene (9.980%). EOZ demonstrated noteworthy antioxidant activity in all tests, with an IC50 of 9.53 ± 0.41 mg/mL in the DPPH test and an EC50 of 87.46 ± 3.19 mg/mL in the FRAP system. The results indicate that EOZ has strong efficacy against C. maculatus, even at low concentrations (1.00 μL/100 g). Note that EOZ killed 20 ± 0% and 13.33 ± 4.44% of adult C. maculatus in inhalation and contact tests, respectively. High concentration (20.00 μL/100 g) resulted in 100% adult mortality in inhalation tests and 96.67 ± 4.44% mortality in contact testing. We then used molecular docking to identify EO major component binding modes by targeting insecticidal and antioxidant protein structures 1R20 and 1R4U. This research helps create insecticides and antioxidants from common ginger essential oil.
