This study reports chemical composition of the essential oils and in vitro antioxidant, antimicrobial and cytotoxic activity of the volatile fraction, extracted using simulations steam distillation-solvent extraction (SDE) method, and methanolic extract from the stems and young leaves of Pterocarya fraxinifolia from Gilan, west-north of Iran for the first time. The extraction yield of volatile ...

Approximately 11% and 25% of annual Canadian oil spill accidents are gasoline and diesel spills, respectively. Gasoline and diesel spills are a challenge to conventional environmental forensic techniques because refinery processes remove most of the higher molecular weight biomarkers. This study presents a tiered environmental forensics strategy that includes such information as site operationa...

fungi release wide spectrum of volatile organic compounds (vocs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...

In a study to determine the stability of the main volatile constituents of Nigella sativa seeds stored under several conditions, eight storage conditions were established, based on the ecological abiotic effects of air, heat, and light. Six replicates each were prepared and analyzed with Headspace-Gas Chromatography-Mass Spectrometry (HS-GC-MS) for three time points at the initial (1st day (0))...

The aim of this research was to determine the chemical composition and nematicidal activity of essential oil of Agastache rugosa flowering aerial parts against the root knot nematode, Meloidogyne incognita, and to isolate and identify any nematicidal constituents from the essential oil. The essential oil of A. rugosa aerial parts was obtained by hydrodistillation and analyzed by GC-FID and GC-M...

Rose water is one of the most important products obtained from Rosa genus (Rosaceae). Although Iran is one of the main producers of rose water, limited research has been done on it. A simple distillation and a Clevenger-type apparatus were used to obtain rose water and rose oil. All the volatile concentrates were investigated for their chemical composition by gas chromatography (GC) and gas chr...

Background & Aim: Peppermint (Mentha piperita L.) oil is one of the most popular and widely used as an essential oil. The aim of this study was to identify of the chemical components of peppermint cultivated in Isfahan climatic conditions. Experimental: The aerial parts of the plants were collected from a filed in Meymeh, Isfahan province in 2012. The essential oil was extracted by a ...
