Current Chromatography - Volume 7, Issue 1, 2020

Green separation science involves extraction, pre-concentration and chromatographic analysis aiming at minimizing environmental impact by reducing energy and reagent usage and reducing or eliminating waste generation. However, the enrichment of trace analytes and/or the analysis of complex matrices most frequently require several steps before analysis, such as extraction, pre-concentration, clean up and preparat Read More

Background: Eugenol is the main constituent of clove essential oil. Past studies have found that clove oil has diverse uses in the pharmaceutical field due to its antioxidant, antibacterial and anesthetic properties. Objective: This work compares the performance of different extraction methods and factors and identifies the effect of the treatments on oil yields and eugenol content. Materials and Methods: Maceration, Hydro distill Read More

Background: Carotenoids are natural plant pigments and precursors of vitamin A, which provide a health benefit, protect against chronic degenerative diseases, and contribute to immune functions. Utilization and identification of foods with a high content of carotenoids received greater attention nowadays. Objective: The present study was aimed at evaluating total carotenoids content (TCC) and carotene compo Read More

Background: The cost-effective and environmentally benign solvent of hydrophobic deep eutectic (DES) was prepared for the removal of Cu (II) from aqueous solution. Hydrophobic DES has been gaining increasing attention from researchers for the replacement of hazardous solvent consumption in liquid-liquid extraction (LLE). Objectives: To synthesize the hydrophobic DES and optimize the parameters for ligandless L Read More

Background: Polyphenolic compounds are known to provide health benefits and protect against degenerative chronic diseases. Utilization and identification of foods with a high content of these compounds are gaining greater attention nowadays. Objective: The present study reports the total phenolic content (TPC), polyphenolic composition and antioxidant activity (DPPH, FRAP and TEAC) of 10 commonly consumed leafy Read More

Background: The application of enantioselective capillary electrophoresis approach for the assessment of the enantiomeric purity of chiral molecules is receiving increased attention. Abscisic acid is one of the chiral sesquiterpenic plant growth regulators that regulate various ecological and physiological roles in higher plants. Enantiomeric determination of ABA is of great concern because of the different biological activit Read More

Background: Cationic surfactants (CSs) such as quaternary ammonium compounds are used as fabric softeners, anti-bacterial agents, and human hair cosmetics. Accurate determination of CSs in environmental water samples is very difficult because of their very low concentration and strong adsorptivity to not only glassware but also to plasticware due to strong hydrophobic and electrostatic attractions. Linear alkylbenzene su Read More
