The possibility to utilize the antibacterial and antibiofilm potential of essential oils (EOs) in dentistry is recognized best seen design EO-based mouthwashes. up-to-date results, obtained with most commonly used formulation being consisted thymol, eucalyptol, menthol, methyl salicylate (Listerine), proved its efficacy against plaque gingival inflammation. However, novel alcohol-free products ...

INTRODUCTION A myriad of volatile organic compounds (VOCs) released by terrestrial vegetation plays an important role in environmental sciences. A thorough chemical identification of these species at the molecular level is essential in various fields, ranging from atmospheric chemistry to ecology of forest ecosystems. In particular, the recognition of VOCs profiles in a context of plant-insect ...

Composition of the essential oil obtained from dried flowering aerial parts of Teucrium scordium L. (Labiatae) was analyzed by GC and GC/MS. Fifty-six components were identified in the essential oil of T. scordium. The major constituents of the oil were beta-caryophyllene (22.8%), (E)-beta-farnesene (10.4%), caryophyllene oxide (8.6%), 1,8-cineole (6.1%) and beta-eudesmol (5.1%).

The first step in the conversion of the isoprenoid intermediate, farnesyl diphosphate (FDP), to sesquiterpene phytoalexins in cotton (Gossypium barbadense) plants is catalyzed by delta-cadinene (CDN) synthase. CDN is the precursor of desoxyhemigossypol and hemigossypol defense sesquiterpenes. In this paper we have studied the mechanism for the cyclization of FDP and the putative intermediate, n...

Introduction Insect oviposition can enhance plant defenses and decrease quality in response to future feeding damage by hatched larvae. Induced resistance triggered egg deposition its negative effect on insect herbivore performance is known for several annual plants but has been much less studied woody perennials, such as species of the Salicaceae. Here we willow Salix babylonica specialist saw...

The molecular and biochemical events underlying the onset of superficial scald in two pear cultivars with different susceptibility (‘Blanquilla’ ‘Conference’) was investigated fruit untreated treated lovastatin, 1-MCP or ethylene. ‘Conference’ pears were characterized by higher content flavonols linolenic acid (18:3), metabolites related to chilling injury resistance. In this cultivar, expressi...

Plants produce and emit a large variety of volatiles that have multiple defense-related functions in response to abiotic or biotic stresses. In comparison with studies on plant volatile–herbivore interactions, little research has been carried out volatile–microbe interactions. the present paper, tea volatile–Colletotrichum camelliae interactions were studied. The results emitted following infec...
