Endocrine disrupting chemicals are chemicals that interfere with any aspect of the endocrine system. Several natural and synthetic chemicals including pesticides have been identified as endocrine disruptors, which potentially inhibit the reproductive activity of the hormonal system. The pervasive occurrence with trace level concentrations and extensive variety are the reported characteristics of these chemicals. In this study, a dispersive liquid-liquid microextraction method coupled with GC-MS ...

The minor ginsenosides with less polarity from Panax notoginseng leaves may have more potent biological activities. Four minor saponins, i.e. gypenoside XVII, ginsenoside Rd2, notoginsenoside Fe and notoginsenoside Fd, were successfully separated from Panax notoginseng leaves after biotransformation by one-step counter-current chromatography using the biphasic solvent system consisting of n-butanol-ethyl acetate-water (1:4:5, v/v/v). 30 mg of the refined extract of Panax notoginseng leaves produ...

A simple method for the analysis of thirteen synthetic musk compounds and six ultraviolet filters in soil samples was developed using a modified dispersive solid-phase methodology known as "Quick, Easy, Cheap, Effective, Rugged and Safe", followed by gas chromatography - triple quadrupole mass spectrometry (GC-MS/MS). The methodology was validated assessing linearity ranges, detection limits, precision, and accuracy. The method detection limit ranged between 0.01 and 10.00 ng g-1 dry weight and ...

Comprehensive two dimensional GC has been utilized for analyzing complex mixtures of hydrocarbons of diesel feeds. Here, we evaluated 19 diesel feeds for their Paraffinic, Naphthenic and Aromatic group compositions dictating their flammability properties. Compositional ranges of feeds were as follows; Paraffins: 9.6-57.8%, Naphthenes: 7.9 - 38.5% & Aromatics: 10.5 - 82.3%. Diesel's flammability performance is estimated by thermodynamic conditions and rates of radical formation of hydrocarbon typ...

Separation of ethane-ethylene mixtures was evaluated using two zeolitic imidazolate frameworks, which are only different from the assemble metal, as stationary phase from Inverse Gas Chromatography data. The chromatographic profiles exhibited peaks adequately resolved. Separation is attributed to the pore sizes of the adsorbents which discern between ethane and ethylene molecule shapes and closed kinetic diameters. The adsorption heats were estimated for each probe molecule from the slopes of th...

Stability indicating reverse-phase HPLC method for simultaneous estimation of dolutegravir sodium and lamivudine encapsulated in the nanoliposomal formulation was developed. The chromatographic parameters namely, organic phase ratio, flow rate, and sample injection volume were selected as independent factors and were optimized by multivariate Box-Behnken design. Responses analyzed were retention time, peak area and resolution. The optimized chromatographic method with Hypersil BDS C8 CN column a...

Cyclodextrins and their derivatives have been used for chiral HPLC selectors, while they are costly to use as mobile phase additives in HPLC. Here, we report application of phenyl column coated permanently with methylated β-cyclodextrin for chiral HPLC. A 0.1% (v/v) phosphoric acid solution containing 1 M NaCl and 0.5% (w/v) methylated β-cyclodextrin was subjected to a phenyl column at a flow rate of 0.5 mL/min at 30 °C for 2 h. Using the precoating phenyl column, all the enantiomers of the four...

In this study, a hydrophobic interaction electrokinetic chromatography method has been developed for simultaneous separation and determination of three diterpenoids in Euphorbiae Lathyris L.: Euphorbia factor L1 , Euphorbia factor L2 and Euphorbia factor L3 . After optimization of separation conditions, the electrolyte solution was 5.0 mM ammonium acetate buffer containing 30 mM sodium dodecyl sulfate in a 60% (v/v) methanol (pH 6.86), 25 kV of electric field across the capillary was applied at ...

Pesticides are excessively used in agriculture to improve the quality of crops by eliminating the negative effects of pests. Among the different groups of pesticides, triazine pesticides are a group of compounds that contain a substituted C3 H3 N3 heterocyclic ring, and they are widely used. Triazine pesticides can be dangerous for humans as well as for the aquatic environment due to their high toxicity and endocrine disrupting effect. However, the concentration of these chemical compounds in wa...

γ-Glutamylpeptides have been identified as potential biomarkers for a number of diseases including cancer, diabetes, and liver disease. In this study, we developed and validated a novel quantitative analytical strategy for measuring γ-glutamylisoleucine, γ-glutamylthreonine, and γ-glutamylvaline, all of which have been previously reported as potential biomarkers for prostate cancer, in HeLa cells using UHPLC-MS/MS. A BEH C18 column was used as the stationary phase. Mobile phase A was 99:1 water:...
