The essential oils obtained by hydrodistillation (Clevenger apparatus) from aerial parts of Astragalus gombiformis were analysed by gas chromatography coupled with mass spectrometry (GC/MS). This study showed that the A. gombiformis essential oils are complex mixtures of important natural compounds, which varied qualitatively and quantitatively between cultivated and wild plants and between phe...

background: summer savory (satureja hortensis l.) is one of the most important medicinal and spice plants cultivated in many parts of the world. objective: a greenhouse experiment was conducted to study the effects of feso4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in s. hortensis. methods: feso4 in four levels (0, 3, 4 ...

background and objectives : the aim of this study was to evaluate the chemical composition and antimicrobial activity of satureja hortensis and trachyspermum copticum essential oils against different kinds of microorganisms in vitro. material and methods : the antimicrobial activity was evaluated by micro broth dilution assay and analysis of essential oils chemical composition by gc and gc/ms a...

the chemical composition of the essential oil obtained from the aerial parts of laurus nobilis l. has been examined by gas chromatography (gc) and gc- mass spectrometery (ms). the main components of the oil were identified. 1,8-cineole was the major component in the oil together with b-terpinyl acetate, terpinene-4-ol, a-pinene, b-pinene, p-cymene, linalool and terpinene-4-ylacetate. the essent...

The use of chemical pesticides to protect agricultural products is a global concern because their adverse effects on the environment and public health. To avoid dangers synthetic herbicides, research has turned natural alternatives. This study was conducted evaluate allelopathic effect essential oil (EO) extracted from Origanum syriacum, onites, majorana. In addition, composition elucidated by ...

This investigation aims to assess the chemical composition and antioxidant properties of Origanum vulgare var. aureum L. essential oil (OEO). The was obtained with a 0.34% (v/w dried weight) yield investigated by gas chromatography-mass spectrometry (GC–MS) analysis. main compounds OEO were found be gamma-terpinene (22.96%), para-cymene (14.72%), germacrene (11.64%), beta-trans-ocimene (9.81%),...

In this study, Melaleuca alternifolia (Maiden and Betche) Cheel (tea tree) oil C. sinensis (L.) Osbeck (orange) was procured, their chemical compositions were characterized by gas chromatography coupled with mass spectrometry, co-injection using authentic samples. The oils rich in monoterpene hydrocarbons making up 84.5% of 48.9% M. oils. High amounts oxygenated monoterpenoids also identified (...

Redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is a native of Southeast Asia recently established in coastal forests of Georgia, SC and Florida. It vectors a wilt fungus, Raffaelea sp., lethal to redbay trees, Persea borbonia L. Spreng, and certain other Lauraceae. No practical monitoring system exists for this beetle so we conducted studies to identify host attractants and develop lures...
