In recent years the growing concern about environmental changes and how we are using the natural resources have triggered a search for natural products as alternatives to synthetic pesticides. The stink bugs produce a wide variety of chemical compounds (semiochemicals) that show potential to manage these insects. The stink bugs Chinavia impicticornis (Stål), C. ubica (Rolston), Dichelops melaca...

Mushrooms are believed to have a great potential for production of bioactive metabolites e. g. terpenes, a group of interesting compounds with diverse chemical properties such as antitumour and antibacterial activity. Cop6 is a terpene cyclase isolated from the mushroom Coprinus cinereus that catalyzes the cyclization of farnesyl diphosphate (FPP) to mainly αcuprenene. In this study gas chromat...

Compositions of true lavender (Lavandula angustifolia) and spike lavender (Lavandula latifolia) essential oils, cultivated and extracted in the Southeast of Spain, were determined by gas chromatography coupled with mass spectrometry detection, obtaining both relative (peak area) and absolute (using standard curves) concentrations. Linalool (37-54 %), linalyl acetate (21-36 %) and (E)-β-caryophy...

INTRODUCTION Dorema glabrum is an endangered species that grow in Transcaucasia and North West of Iran. The plant has extensive uses e.g. as an herbal remedy or food additive in these regions. The chemical composition of hydrodistilled oil of D. glabrum growing in Iran was analyzed by GC-MS for the first time. METHODS The essential oil of air-dried roots was obtained by hydrodistillation usin...

The Myrtaceae plants are cultivated for their edible fruits and folk medicinal uses. Likewise, leaves, flowers, fruit essential oils (EOs) described to have antiproliferative, antimicrobial, antioxidant activities. This work analyzed the chemical compositions evaluated antiproliferative activities of (EO) Myrcia bella Cambess, fallax (Rich.) DC., guianensis (Aubl.) Eugenia aurata O. Berg, punic...

Abstract In fungi, little is known about connections between volatile organic compound (VOC) formation and developmental stages that are amongst others triggered by fruiting-related genes (FRGs). We analysed the volatilomes of Schizophyllum commune during different in a variety FRG-deletion strains wild-type strains. The deletion Δ tea1 , wc-2 hom2 were unable to develop fruiting bodies, fst4 f...

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 ...

Eleven Tunisian natural populations of Lavandula multifida L., from different geographic regions and bioclimates, were assessed for their variability using six polymorphic loci and 35 terpenoids. Isozymes were revealed by 13% gel electrophoresis. Volatiles were analysed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). A high genetic diversity within populations and w...
