Because little is known about the effects of individual flavorants in electronic cigarette (e-cig) fluids on human platelet aggregation, we tested for the direct effects of 15 common e-cig flavorants on adenosine diphosphate (ADP)-induced human platelet aggregation ex vivo. To better understand a potential mechanism of action of flavorants, we quantified 2 phases of aggregation. Human platelet-ric ...
... Essential oils (EOs) have drawn growing attention due to an increased risk of chemical contamination upon the application of synthetic fungicides to post-harvest fruits. This experiment investigated the antifungal activity of seven EOs at different concentrations of 0.5, 1, 2, 4, 6, 8, and 10 μL mL⁻¹ against the fungus Botrytis cinerea in two methods of liquid and vapor phase. Besides the chemical ...
... Plant volatiles, constitutive or induced, are perceived by insect pests to locate the host plant and also by natural enemies to locate the host insect. These plant volatiles can be utilized to develop attractive or repellant lures for pest management. Studies were carried out to identify the plant volatiles which are induced in pigeonpea, Cajanus cajan (L.) Huth due to the herbivory of blister bee ...
... Sagebrush (Artemisia spp.) are dominant wild plants in large areas of the U.S., Canada and Mexico, and include several species and subspecies. The hypothesis was that there are significant differences in essential oil (EO) content, composition, and biological activity of sagebrush within the Bighorn Mountains, U.S. The EO yield in fresh herbage varied from 0.15 to 1.69% for all species, including ...

... Essential oils (EOs) produced by plants in the Lamiaceae family may provide new insecticidal molecules. Novel control compounds are needed to control Drosophila suzukii (Matsumura), a severe economic invasive pest of thin-skinned fruit crops. Thus, we characterized the main compounds of EOs from three rosemary Rosmarinus officinalis ecotypes (ECOs) and evaluated their toxicity to D. suzukii adults ...

Abstract:
... The genus Hedychium (Zingiberaceae), popularly known as ginger lily is widely distributed in China, India, and Southeast Asia. Hedychium species are widely used in fragrance, paper, ornamental, cosmetics, medicine, and food. The extracts and essential oils of Hedychium have been reported to have multiple bioactivities, such as antioxidant, antimicrobial, cytotoxicity, anti acetylcholinesterase, an ...
... The hydrodistilled essential oils from eighteen samples of Salvia rosmarinus Spenn. collected in six localities of Elba Island (Tuscany, Italy) during three different seasonal periods were analyzed by GC-MS for the first time. Fifty-five components were identified, representing 96.8–99.6% of the total chemical composition. All the tested essential oils were characterized by a high content of monot ...
... In peneide shrimp, diseases caused by Vibrio species are the source of serious economic losses worldwide. Essential oils from Lamiaceae species are sources of bioactives for aquaculture, with potential antimicrobial and antioxidant activity. The aim was to investigate the chemical composition, antimicrobial activity and antioxidant effects of essential oils from five species of Lamiaceae against V ...
... Several Salvia species are among the most valuable aromatic herbs used for industrial and pharmaceutical applications. Hence, under greenhouse trial conditions, the effects of chitosan treatment (0, 100, and 200 mg L⁻¹) and water deficiency stress on the morphological, physiological, and biochemical features of two Salvia species were examined. Significant changes were seen in chlorophyll a, root ...
... This study delineates the effects of incorporation of six selected essential oils into the extra virgin olive oil (EVOO) on its volatile profile, sensory attributes, oxidative stability, fatty acid composition, and their nutritional quality. Results indicate that headspace bouquets of flavored EVOO consisted mainly on the main components of the aromatizing essential oils being carvacrol, 1,8‐cineo ...
... Lemon balm, mint, and basil were used to determine whether light modification (plants grown under pearl shade nets with 40 % shaded index or in un-shaded open field) could improve the quantity and quality of essential oils (EOs) and antioxidant activity. The yield of EOs of lemon balm, mint and sweet basil obtained after 120 min of hydrodistillation was 0.18, 2.00, and 1.12 mL/100 g, respectively. ...
... The repellent properties of volatile organic compounds (VOCs) emitted by several companion plant species (CPs) were tested on the rosy apple aphid, Dysaphis plantaginea (Passerini) (Hemiptera: Aphididae), in a new dynamic tubular olfactometer connected to a dynamic plant chamber. This device allows a rapid and direct measurement of the repellency of whole plants on an aphid population. The VOC pro ...
... Allspice (Pimenta dioica L.) has been used since time immemorial for its culinary and medicinal qualities. Its unique characteristics are flavor conglomerates of cloves, nutmeg and cinnamon. Eugenol (60–90% in the berries, >90% in the leaves) is the key component followed by 1,8-cineole, α-humulene, β-caryophyllene and cadinene derivatives of pimenta essential oil that imparts health and wellness. ...
... Imidacloprid (IMI) is a widely used neonicotinoid insecticide that has toxic effects on nontarget organisms. 1,8-Cineole (eucalyptol) is purified from essential oils in several aromatic plants and can prevent xenobiotic toxicity. The kidney is a major organ for xenobiotic elimination and thus has high risk of exposure. The purpose of this research was to clarify the effect of IMI exposure on autop ...
... Diisobutyl phthalate (DiBP), one of the commonly used plasticizers in industry, is an endocrine disruptor and environmental contaminant that can persist in water and threaten the health of aquatic creatures. Eucalyptol (Euc), a monoterpenoid extracted from plants, has been proved to have anti-inflammatory, antioxidant, and detoxification properties. However, the protective mechanism of Euc against ...
