Summary: This study investigated the chemical composition, acetylcholinesterase inhibition, and molecular docking of the essential oil from Knema hookeriana Warb. The essential oil primarily consisted of beta-caryophyllene, germacrene D, delta-cadinene, germacrene B, and bicyclogermacrene. The essential oil exhibited acetylcholinesterase activity with an IC50 value of 70.5 μg/mL. Molecular docking studies showed that beta-caryophyllene and delta-cadinene had good binding affinities towards AChE.

Summary: The quality of essential oils of common thyme and spearmint significantly decreases during long storage and following a 25-week experimental period, affecting the antioxidant activity. The first 15-20 weeks post-harvesting are crucial for maintaining the quality of the essential oils. The percentage content is not a reliable indicator of the quality of essential oil as a crop product for the food and pharmaceutical industry.

Summary: This study compares the essential oils extracted from Mentha suaveolens Ehrh. from Italy. The results show that hydrodistillation yields a higher amount of essential oil, while the dried plant contains a higher concentration of essential oil. Gas chromatography-mass spectrometry analysis reveals that the essential oils belong to the piperitenone oxide-rich chemotype. The study also demonstrates that samples rich in piperitenone oxide exhibit higher potency against Candida albicans.

Summary: The chemical composition of essential oils of Artemisia vulgaris plants collected in Lithuania was reported, with germacrene D identified as the principal constituent. Mugwort essential oils rich in germacrene D were found to be rare and notably toxic. Other major compounds identified included 1,8-cineole, beta-pinene, sabinene, cis-thujone, beta-caryophyllene, caryophyllene oxide, alpha-humulene, and davanone.

Summary: This study evaluated the chemical composition of the essential oils (EOs) of Guatteria schomburgkiana and Xylopia frutescens and measured their herbicide activity against invasive species. The results showed that Xylopia frutescens had the highest yield and that the EOs had varying effects on different species. The study also conducted molecular docking to identify the compounds responsible for the herbicidal activity.

Summary: This study investigated the composition of essential oils from Litsea glauca and Litsea fulva in Malaysia. Gas chromatography and gas chromatography-mass spectrometry were used to fully characterize the essential oils. The results identified various components in the essential oils and indicated moderate inhibitory activity on acetylcholinesterase and butyrylcholinesterase assays. The findings suggest that the essential oils from the genus Litsea have potential applications in characterization, pharmaceutical, and therapeutic fields.

Summary: The study found that Chromolaena odorata essential oil has sedative activity in mice, with caryophyllene oxide identified as the key compound responsible for this effect. Caryophyllene oxide showed potent CNS depressant effects and effectively reduced locomotor activity in mice. Interestingly, the precursor beta-caryophyllene also exhibited sedative activity, highlighting the potential of sesquiterpene compounds for managing sleep and CNS-related disorders.

Summary: Plectranthus L 'Her is a large genus of Lamiaceae family that includes about 300 species distributed in the tropical and warm regions of the Old-World. Some species are edible and used for traditional medicinal purposes in several countries. Phytochemical investigations have revealed that species in this genus contain diterpenoids with abietane, phyllocladanes, and kaurene skeleton. This study analyzed the essential oil composition of Plectranthus ornatus, an invasive and ornamental plant with traditional medicinal uses, for the first time in Israel, using gas chromatography-mass spectrometry (GC-MS). Comparisons were made with other essential oils from P. ornatus accessions.

Summary: This study investigated the chemical compositions and cytotoxic activities of essential oils from six Baccharis species belonging to subgenus Coridifoliae. The results showed that the essential oils of most species exhibited cytotoxic effects against cancer and normal kidney cells, with B. erigeroides showing cytotoxicity specifically against LLC-PK1 cells. This article expands the current knowledge about the chemical-biological properties of Baccharis subgenus Coridifoliae and discusses the therapeutic potentials of these economically unexploited plants.

Summary: This study analyzed the chemical composition of the essential oils from aerial parts of a rare species of Nepeta collected in two locations in Sicily and found that the main constituents were β-pinene, γ-terpinene, β-caryophyllene, and germacrene D. The chemical profile of these essential oils was compared with previous studies on Nepeta taxa oils.

Summary: This study investigated the chemical composition of essential oils from feijoa leaves and stems and their potential as natural anti-aging agents. The oils showed inhibitory effects against different enzymes and exhibited valuable binding interactions. Caryophyllene oxide and alpha-zingiberene showed promising interactions with acetylcholinesterase, while linalool, tau-cadinol, and spathulenol had strong binding energy to collagenase and elastase. This study provides scientific evidence for the use of feijoa essential oils in anti-aging formulations and as an adjuvant for Alzheimer's disease prophylaxis.

Summary: The essential oils extracted from Satureja macrostema leaves in different regions of Mexico exhibited antioxidant and antibacterial activities. The main components were identified as trans-piperitone epoxide, cis-piperitone epoxide, and piperitenone oxide. The variability in the presence and abundance of these compounds in comparison with other studies can be attributed to climatic factors and plant maturity.
