dracocephalum kotschyi (lamiaceae), as one of the remarkable aromatic plants, widely grows and also is cultivated in various temperate regions of iran. there are diverse reports about the composition of the oil of this plant representing limonene derivatives as its major compounds. there is no report on cloning of mono- or sesquiterpene synthases from this plant. in the present study, the aroma...

carbon disulfide is used predominantly in the manufacture. it has affects the nervous system. in this study, the applicability of spme as a passive sampler for determination of carbon disulphide in air was studied. effect of sampler and environmental parameters on uptake of carbon disulphide was studied as well. four fibers were tested to select the best sampler for determine carbon disulfide i...

this research is on the improvement of the procedure to determination of trace levels of antidepressant drug; fluoxetine in wastewaters. in this research a silica based sol-gel was applied for the extraction of fluoxetine from water samples. this two-phase technique is consisting of aqueous samples of fluoxetine (donor phase) and silica based nanocomposite prepared by sol-gel technique (accepto...

Phthalate esters are endocrine disrupters or mutagens. They are widely used as plasticizers and can be usually found in environmental samples, such as food, soil and polluted air. However, it is difficult to directly determine phthalate esters owing to their relatively low concentration and complex matrices. Therefore, preconcentration and separation have become increasingly important. In recen...

Honari Department of Chemistry, Faculty of Science, Islamic Azad University Shahr-E-Rey Branch, Shahr-E-Rey, Iran Department of Plant Breading and Biotechnology, Agriculture and Natural Resources Faculty, Tehran ...

Solvent extraction remains one of the fundamental sample preparation techniques in the analysis of environmental solid samples, but organic solvents are toxic and environmentally harmful, therefore one of the possible greening directions is its miniaturization. The present review covers the relevant research from the field of application of microextraction to the sample preparation of environme...

A simple, fast, inexpensive, and sensitive technique for the detection and identification of flammable or combustible liquid residues on the skin of arson suspects is presented. The use of solid phase microextraction (SPME) for the analysis of ignitable liquid residues has been demonstrated and it is shown in this work that this technique is effective in extracting these liquid residues at extr...
