Endophytic bacteria play a crucial role in plant life and are also drawing much attention for their capacity to produce bioactive compounds of relevant biotechnological interest. Here we present the characterisation of the cultivable endophytic bacteria of Lavandula angustifolia Mill.-a species used since antiquity for its therapeutic properties-since the production of bioactive metabolites fro...

Essential oils extracted from flower petals of palmarosa (Cymbopogon martini), evening primrose (Primula rosea), lavender (Lavandula angustifolia) and tuberose (Polianthus tuberosa) were tested for their antibacterial activities against gram-positive and gram-negative bacteria. Different concentrations of each essential oil ranging from 10-100% were tested. Both gram-positive and gram-negative ...

OBJECTIVES Monoterpenes can positively or negatively affect human health depending on their concentrations. To assess the atmospheric risk for greenhouse workers, monoterpene concentrations and personal exposure in herb-growing greenhouses were measured. METHODS Monoterpene concentrations in a commercial greenhouse, where rosemary (Rosmarinus officinalis L.) and lavender (Lavandula angustifol...

objective(s):neurodegenerative alzheimer’s disease (ad) is associated with profound deficits in synaptic transmission and synaptic plasticity. long-term potentiation (ltp), an experimental form of synaptic plasticity, is intensively examined in hippocampus. in this study we evaluated the effect of aqueous extract of lavender (lavandula angustifolia) on induction of ltp in the ca1 area of hippoc...

male infertility evaluation is important to recognize an origin and provide treatment if the etiology is correctable. the aim of the present study was to investigate the protective role of lavandula angustifolia in impaired spermatogenesis caused by cadmium chloride in male rats. 36 male wistar rats were allocated in 6 groups. cadmium chloride was injected for 3 consecutive days (0.5 mg/kg) in ...

The aim of the study was comparing the chemical composition of the essential oils from five varieties of lavender (Lavandula angustifolia L.), and its biological activity against two pathogenic bacteria, Staphylococcus aureus and Pseudomonas aeruginosa. In the comparison we included the following varieties: 'Munstead', 'Munstead Strain', 'Lavender Lady', 'Ellegance Purple' and 'Blue River'. Sel...

The influence of shrubs used as nurse plants was tested on the growth of Cupressus atlantica, on microbial activity and on arbuscular mycorrhizal (AM) soil potential in a Mediterranean environment. An experimental plantation was conducted combining uninoculated, arbuscular mycorrhized Cypress seedlings and an association between Lavandula stoechas planted close to newly planted C. atlantica see...

The microbiological contamination of raw plant materials is common and may be adequately reduced by radiation processing. This study evaluated the effects of gamma- and e-beam ionizing radiations (25 kGy) on three plants used as food or as medicinal products (Thymus vulgaris L., Eucalyptus radiata D.C., and Lavandula angustifolia Mill.) as well as their effects on extracted or commercial essent...

ABSTRACT: Chemical composition of Lavandula angustifolia was studied by solvent free microwave extraction (SFME) and hydrodistillation (HD) methods. 1, 8-cineole (42.7% and 37.9%), Camphor (26.1% and 21.3%) and Borneol (31.2% and 21.6%) were the major compounds that obtained by SFME and hydrodistillation, respectively. The antibacterial activity of extracted oils was investigated against Gram-p...
