Chemical composition and antimicrobial activity of essential oils from six lavender (Lavandula angustifolia Mill.) cultivars

Sıla Barut Gök,

Abstract: Microbial spoilage is a common source of food spoilage, which occurs due to the action of microorganisms, which include moulds, yeasts, and bacteria (Amit et al. 2017). Preservation of food materials from degradation during production, storage and marketing is an important issue in the food industry (Tenore et al. 2011). Chemical food additives and preservatives are mostly considered safe, but several of them have negative and potentially life-threatening side effects (Gyawali and

This study investigates the antiepileptic potential of the methanolic extract of Vitex negundo leaves in seizure models induced in mice using lithium-pilocarpine, maximal electroshock (MES), strychnine, picrotoxin, and pentylenetetrazol. The extract demonstrated a protective effect against seizures induced by MES and enhanced the efficacy of standard anticonvulsant drugs against chemically-induced seizures. The results suggest that the flavonoids present in the methanolic extract may exert their antiepileptic effects by modulating GABAergic pathways and blocking sodium (Na⁺) channels in a dose-dependent manner. These findings highlight the potential of Vitex negundo methanolic extract as a promising therapeutic candidate for epilepsy treatment. Keywords: Vitex negundo, methanolic extract, maximal electroshock (MES), antiepileptic, animal models, GABAergic pathway

This study investigated the phytochemical characteristics, antibacterial activity, and synergistic potential of essential oils derived from Romanian lavender. Gas Chromatography–Mass Spectrometry (GC/MS) analysis revealed that linalool is the main compound in all lavender essential oils, with concentrations ranging from 29.410% to 35.769%. Linalyl acetate was found in similar concentrations to linalool. Other significant compounds included 1,8-cineole (8.50%), lavandulyl acetate (5.38%), trans-β-ocimene (6.90%), and camphor (7.7%). A 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) test was used to assess antioxidant capacity, with substantial free-radical-scavenging activity shown in the IC50 values determined. The antibacterial efficacy of the oils was higher against Gram-positive bacteria than Gram-negative bacteria, with variations in minimum inhibitory concentrations (MICs), the extent of inhibition, and evolution patterns. The study also explored the oils’ ability to enhance the efficacy of ampicillin, revealing synergistic interactions expressed as fractional inhibitory concentration indices. In silico protein–ligand docking studies used twenty-one compounds identified by GC-MS with bacterial protein targets, showing notable binding interactions with SasG (−6.3 kcal/mol to −4.6 kcal/mol) and KAS III (−6.2 kcal/mol to −4.9 kcal/mol). Overall, the results indicate that Romanian lavender essential oils possess potent antioxidant and antibacterial properties, and their synergistic interaction with ampicillin has potential for enhancing antibiotic therapies.
