“…53,54 Notable compounds like β-pinene, cis -β-elemene, α-pinene, geranyl acetate, geranial, neral, and geraniol were identified as major constituents of the D. benenica EOs, and are well-known for their antimicrobial properties. 54–56 Indeed, β-pinene and α-pinene, 2 monoterpenes, have exhibited antimicrobial activity against bacterial and fungal strains, including drug-resistant ones. 57 EO from Syzygium szemaoense , primarily consisting of cis -β-elemene, has demonstrated noteworthy antimicrobial properties against bacteria and fungi.…”

In recent years, essential oils (EOs) have gained popularity for their potential as natural antimicrobial agents and mosquito larvae control. This study aimed to explore the chemical composition of EOs extracted from the leaves and rhizomes of Distichochlamys benenica Q.B. Nguyen & Škorničk, and to evaluate their mosquito larvicidal and antimicrobial activities. The EOs were obtained using hydrodistillation and subjected to gas chromatography (GC) and GC-mass spectrometry to determine their chemical constituents. The main components identified in the leaf EO were β-pinene (47.7%), cis-β-elemene (8.5%), and α-pinene (7.8%), while the rhizome EO mainly consisted of geranyl acetate (25.7%), geranial (23.3%), neral (16.6%), and geraniol (8.4%). The mosquito larvicidal activity of the EOs was evaluated using larvae of Aedes aegypti and Culex quinquefasciatus during 24 and 48 h of treatment. The results demonstrated that these EOs effectively inhibited the mosquito larvae, with LC50 values ranging from 31.15 to 71.53 μg/mL and LC90 values ranging from 46.28 to 148.66 μg/mL. Additionally, the minimum inhibitory concentration (MIC) and half-maximal inhibitory concentration (IC50) values were used to evaluate the antimicrobial efficacy of EOs. Both EOs exhibited potent antimicrobial effects against Enterococcus faecalis ATCC 299212, Staphylococcus aureus ATCC 25923, Bacillus cereus ATCC 14579, Pseudomonas aeruginosa ATCC 27853, and Candida albicans ATCC 10231, with MIC values ranging from 16 to 64 μg/mL and IC50 values ranging from 4.67 to 45.67 μg/mL. Overall, the mosquito larvicidal and antimicrobial activities of D. benenica EOs highlight their potential as natural alternatives for combating mosquito-borne diseases and microbial infections.

For the first time, the component composition of the low-molecular-weight metabolome of perfoliate pondweed (Potamogeton perfoliatus L., family Potamogetonaceae), which grows in the Astrakhan region (lower zone of the Volga river delta), has been investigated. Low molecular weight organic compounds (LMWOCs) in the composition of essential oil were obtained from dried plants by steam hydrodistillation using the Clevenger apparatus. The qualitative and quantitative compositions of the LMWOCs were investigated using gas chromatography-mass spectrometry (GC/MS complex TRACE ISQ (Thermo Scientific) with a quadrupole mass analyzer). The low molecular weight metabolome of P. perfoliatus contained 164 components, of which 151 were identified. Major LMWOCs were carboxylic acids – tetradecanoic (69.7%) and hexadecanoic (10.1%), as well as phytol (3.4%) and phyton (1.4%), characterized by diverse biological activities. The antioxidant activity of an aqueous-alcoholic extract of P. perfoliatus was investigated by a photometric method based on the reaction of DPPH (2,2-diphenyl-1-picrylhydrazyl) dissolved in ethanol with an antioxidant sample. It has been shown that P. perfoliatus extract has more pronounced antioxidant properties than the tested drugs (ascorbic acid and emoxipine). P. perfoliatus from the lower zone of the Volga River delta can be considered as a naturally renewable resource for obtaining raw materials for creating effective composites of new generation algicides to combat cyanobacterial "bloom", as well as for obtaining valuable natural forms of LMWOCs of plant origin for various types of application in pharmacology, medicine, cosmetology, food industry, and other industries.
