Summary: This study aimed to determine if there are significant differences in essential oil yield, composition, and biological activity of sagebrush within the Bighorn Mountains, U.S. The results showed significant variability in the essential oil profile, antioxidant capacity, and chemical composition between different species and subspecies of sagebrush. While no significant antimicrobial, antimalarial, or antileishmanial activity was found, some accessions yielded essential oil with significant concentrations of specific compounds that could meet specific industry needs.

Summary: The objective of this study was to evaluate the production, contents, and essential oil (EO) components of sage as a function of the diurnal variation. The results showed that harvesting between 4:00 and 6:00 p.m. revealed the highest EO percentage, while harvesting between 04:00 and 06:00 a.m. indicated the minimum EO percentage. The study also identified the major EO compounds and their variations based on different harvesting times.

Summary: This study investigated the anti-proliferative and anti-migratory effects of Thuja homeopathic mother tincture (MT) and its bioactive component on cervical cancer cells. The results demonstrated that Thuja possessed significant anti-cancer potential and induced cell death through apoptosis and autophagy pathways. The bioactive component thujone also showed strong anti-cancer effects and had good drug competitiveness. These findings suggest the potential therapeutic efficacy of Thuja in treating HPV-infected cervical cancer.

Summary: Plant micropropagation is suggested as a promising solution for improving medicinal plants and commercial production of phytochemicals. Tree Wormwood has been identified as a potential source for chamazulene production, but the presence of beta-thujone poses limitations. This study aims to develop cultivation protocols of tree wormwood and study the effects of plant growth regulators on volatile metabolites production and biosynthesis of chamazulene. Biotechnological production of essential oils showed significantly increased yield, while combinations of PGRs and culture conditions exhibited promising results in inducing chamazulene biosynthesis.

Summary: This study investigated the insecticidal activity of essential oils (EOs) from plants of the Lamiaceae family against Fall Armyworm (FAW). The EOs from Hyptis marrubioides and Ocimum basilicum showed toxicity to FAW, with multiple active substances identified. Furthermore, these EOs were found to be harmless to the parasitoid Trichogramma pretiosum, suggesting their potential use in integrated FAW pest management programs.

Summary: Trachymene incisa subsp. incisa is an Australian endemic taxon with variations in leaf trichomes abundance and length. Analysis of essential oil composition shows significant differences in sesquiterpene hydrocarbons between the particularly hairy variant and the typical glabrous one, leading to identification of three different chemotypes based on main compounds.

Summary: The study determined the chemical compounds and antifungal effects of Artemisia persica Boiss essential oil on six toxigenic fungal strains. The essential oil showed acceptable antifungal activity against Aspergillus strains, particularly Aspergillus ochraceus and Aspergillus parasiticus. It can be utilized for preventing fungal contaminations in food crops.

Summary: This review article provides an overview of Lavandula X intermedia (lavandin, LI) in terms of biology, chemistry, biological effects, and applications. Lavandin has received limited attention compared to Lavandula angustifolia (LA), which is considered superior and extensively researched. The article aims to provide a comprehensive review of LI and evaluate its perceived inferior status. Lavandin oil shares similar chemical composition with LA but has a higher content of terpenes, resulting in camphor notes that are less desirable in perfumery. However, lavandin has advantages such as higher essential oil yield and reduced production cost, making it a preferred lavender crop for cultivation.
