The focus of the present study was to investigate the chemical composition of essential oil of Salvia hydrangea DC. ex Benth. growing wild in Kiasar-Hezarjrib, Iran. In addition, effects of altitude and some soil properties on the essential oil quality and quantity of S. hydrangea was identified. The samples collected from two altitudes (1100 and 2000 m) in blossoming period, were analyzed by h...

Rosmarinus officinalis is one of the most important medicinal and aromatic plants around the world. Essential oil as a weapon against biotic and abiotic stresses plays an important role in essential oil bearing plants. In this study the essential oil content and constituent of plants containing bacterium-gall on the shoots and crown was compared with non-contaminated plants. Essential ...

Background & Aim: Eucalyptus L'Her. [an aromatic genera of the family (Myrtaceae)] is native to Australia and other tropical species is planted worldwide. The purpose of this study is to extract and identify the essential oils components of four species of Eucalyptus L'Her. cultivated in botanical garden of Kashan, Central Iran. Experimental: Leaves of E. largiflorens</em...

yarrow (achillea spp.) belonging to the family of asteraceae with useful properties, such as anti-diaphoretic, anti-hemorrhagic, anti-inflammation, anti-biotic, anti-fungal, anti-bacterial, carminative and anti-oxidant effects. the present investigation assessed the morphological diversity of achillea aucheri, which is indigenous plant from damavand mountain of iran. the samples were collected ...

The aim of this study is to develop a microemulsion product from a plant essential oil having the highest anti-tyrosinase activity. The in vitro anti-tyrosinase activity of six essential oils extracted from six edible plants was compared. The oil of Cymbopogon citratus demonstrated the highest activity which was significantly nontoxic to normal human cells. The GC-MS data indicated that gerania...

we studied the antioxidant activities of the essential oils of zataria multiflora boiss. (zeo) and bunium persicum (boiss.) b. fedtsch (beo) in mixed form on linseed oil using (dpph•), ­(­abts•+), h2o2 scavenging, and reducing power assays. after calculation of ic50 for zeo and beo separately, interactions of the essential oils were investigated at the form of mixture and the results were given...

Aedes aegypti and Anopheles gambiae are two mosquito species that represent significant threats to global public health as vectors of Dengue virus and malaria parasites, respectively. Although mosquito populations have been effectively controlled through the use of synthetic insecticides, the emergence of widespread insecticide-resistance in wild mosquito populations is a strong motivation to e...

Background & Aim: Essential oils are isolated from different sections of plants such as flowers, seeds, leaves, stems and roots. Essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. Experimental: Essential oil are obtained by several isolation methods, such as hydrodistillation (HD...

Using GC-MS the volatile composition of Jasonia glutinosa D. C., was studied by comparing two different methods for the isolation of a volatile fraction: distillation from the fresh plant in order to obtain the essential oil, and direct thermal desorption (DTD). Compared with essential oil extraction the main advantages of the DTD technique are the smaller sample amount required, and the increa...
