The chemical composition of essential oil of Cyperus rotundus L. grown in Iran was studied by hydrodistillation and GC and GC-MS. Analysis of the chemical composition of the oil showed the predominance of sesquiterpene compounds, with the presence of monoterpenes. Twenty-two compounds were identified from oil of C. rotundus, of which cyperene (37.9...

In this study we investigated the electrocatalytic oxidation of anti-inflammatory drug (paracetamol) on Nickel and Nickel–copper alloy modified glassy carbon electrodes (GC/Ni and GC/NiCu) in alkaline solution. These electrodes prepared by galvanostatic method and different electrochemical techniques such as cyclic voltammetry and chronoamperometry...

The essential oils obtained by hydrodistillation of aerial part of Cyperus difformis L., and Cyperus arenarius Retz grown in Iran were analyzed by GC-MS. Analysis oils showed the predominance of sesquiterpenes compounds in addition to monoterpenes. Twenty-three components of C. arenarius and Twentynine components of C. difformis representing 87.8 %...

The essential oils obtained by hydrodistillation of aerial part of S. littoralis and S. wardianus grown in Iran were analyzed by GC/MS. Twenty seven components of S. littoralis and S. wardianus representing 85.5% and 86% of the oils were identified respectively. The major components in both oils were cyperene and cyperotundone, representing 18.7% a...

Semiconducting lead sulfide film was deposited on Stainless Steel (SS) electrode by cyclic voltammetry (CV) at room temperature. Electrochemical impedance spectroscopy (EIS) and cyclic voltammetry were used to investigate the electrochemical properties of PbS film in Na2SO4 solution. The voltammetric results showed that oxidative dissolution of PbS...

... The essential oil is the main active ingredient of CR, which is mainly studied by gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) (Aghassi et al., 2013). At present, nearly 100 volatile oil components of CR have been identified. ...
... This sedge protects soil from wind erosion and is grazed by animals. Furthermore, C. arenarius is economically important as a source of essential-oil components, Cyperene and cyperotundone (Feizbakhsh et al., 2012). Because salinity and plant density can be a major determinant of C. arenaulis in its natural habitat, this research was designed to find out the ability of C. arenarius to tolerate sea-water salinity under various levels of intraspecific competition. ...
... The modification has also been applied in an attempt to reduce poor voltammetric responses caused by sluggish electrode kinetics and electrode fouling encountered at bare electrode which decrease sensitivity and reproducibility (Bouabi et al. 2016). Modifiers such as multiwalled carbon nanotube-cetyltrimethyl ammonium (Gowda et al. 2015), chitosan (Bouabi et al. 2016), graphene (Kang et al. 2010), carbon nano-tube composite film (Li et al. 2006), magnesium diboride microparticles (Zidan et al. 2011a(Zidan et al. , 2011b, nafion/TiO 2 -graphene (Fan et al. 2011), bismuth oxide nanoparticles (Zidan et al. 2011a(Zidan et al. , 2011b, nickel and nickel-copper alloy (Feizbakhsh et al. 2012), graphene oxide (Zidan et al. 2014), multiwalled carbon nanotubes and dopamine nanospheres functionalized with gold nanoparticles (Liu et al. 2014), nickel oxide nanoparticles and carbon black (Deroco et al. 2014), cuprous oxide nanoparticles-graphene (Yang et al. 2015), graphene (Fernandez et al. 2015), single-walled carbon nanotube/ nickel nanocomposite (Ngai et al. 2015), cadmium selenide microspheres (Yin et al. 2012), and poly(glycine) (Kuskur et al. 2015) have offered great success for the decrease in overpotential and increase of sensitivity during oxidation of paracetamol. Even though the aforementioned modifiers have proved to be effective, a search for new combinations should still continue so that better sensitivity, selectivity, and good stability are achieved during electrochemical detection. ...
... de, only a few members including C. fedia, C. kobomugi, C. pumila, C. humilis, C. pendula, and C. distachya have been previously investigated for their phytochemical constituents. This is unfortunate because Carex plants are characterized by the production of stilbene derivatives and other bioactive polyphenols including lignans and flavonoids [3]. Feizbakhsh et al (2012) identified essential oils composition of C. pseudofoetida aerial parts from Iran [4]. Manhart (1986) reported foliar flavonoids of the North American members of the Carex section Laxiflorae [5]. Four metabolites, named carexanes I-L, have been isolated from the roots of C. distachya Desf, an herbaceous plant living in the Mediterranean ...
... The CVs and the photoelectrochemical measurements of the prepared electrodes have been collected at the bias voltages of þ0.8 V (SCE) and À0.3 V (SCE), that are respectively above and below the flat band potential of the OLEA-coated PbS NCs (0.057 V), as estimated from the Mott Schottky plot reported in Fig. S7, according to ref. 42. Such a plot shows a linear trend, intercepting the potentials axis at the flat band potential of 0.057 V, with a negative slope, according to the typical p-type behavior of the PbS NC semiconductor [42]. ...
