Purpose: To carry out gas chromatography-mass spectrometry (GC-MS) analysis of the phytochemical content root essential oil Saussurea lappa Clarke Asteraceae (Costus, SLEO), and to evaluate its physicochemical, antimicrobial cytoxic properties.
 Methods: The was extracted from plant’s roots by steam distillation using a Clevenger system. Various physicochemical parameters for including ref...

Tagetes minuta L. belongs to Asteracea family it is an annual species native of South American, although it has become widespread throughout the world. This species is especially well adapted to disturbed habitats. Tagetes minuta oil found a good market in perfumery and flavour industry. Many studies on Tagetes minuta have reported that the composition of exteracted volatile components varied a...

Abstract Anethum graveolens L. (Dill) is an aromatic, medicinal, and food plant that widely known in the world. This paper presents results of study essential oil A. graveolens, which was cultivated Stavropol region (Russia, North Caucasus) to restore its growth. Herb variety “Scythian”, collected different fields limited company “Cossack agriculture “Staropavlovskoe”. The obtained by Clevenger...

A suitable model for predicting the product quality of vacuum gas oil (VGO) catalytic hydrocracking is developed. Data were obtained using an experimental catalytic hydrocracking reactor loaded with the Ni-Mo/Al2O3-SiO2 catalyst. A set of experimental runs was conducted under various operating temperatures from 380 to 450 ℃. Three distribution models were used t...

Background & Aim: Secondary metabolites with bioactive and functional properties in essence of aromatic plants can be useful for improvement of quality and persistence of food as natural preservative.  The aim of this study was to evaluate the in vitro antibacterial of essential oils of some of the medicinal plants collected from Chaharmahal va Bakhtiari Province, Iran. Experimental: ...

Bioethanol is among the most promising of biofuels because it has an energy content similar to gasoline while generating lower pollutant emissions than gasoline. But, in order to be used as an automotive fuel mixed with gasoline, ethanol must have less than 0.5 wt % of water. To achieve required ethanol purity, in light of the fact that the ethanol water mixture forms an azeotrope, unconvention...

In this work, we obtain and compare the control properties of thermally coupled reactive distillation sequences and thermally coupled extractive distillation sequences with those of conventional reactive and extractive distillation configurations. All sequences have been designed using a multiobjective genetic algorithm with restrictions. The theoretical control properties of those schemes were...

the possibility of applying membrane distillation to support the fermentation process was investigated. the capillary polypropylene membranes were assembled in the membrane modules. the studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. the performance o...
