A new graphene nanocomposite modified electrode as efficient voltammetric sensor for determination of eriocitrin

Eriocitrin: A review of pharmacological effects

The present study aimed to recognize the recent literature to highlight the pharmacological impacts and highlight the therapeutic potential of the active molecule eriocitrin. Citrus limon are a good resource of the flavanone eriocitrin (eriodictyol 7-O-β-D-rutinoside). Eriocitrin has potent biological actions due to its strong antioxidant, antitumor, anti-allergic, antidiabetic and anti-inflammatory activities. Eriocitrin is more potent in suppressing oxidative stress in diabetes mellitus (DM) and other chronic diseases incurred by excessive oxidative stress. During metabolism, eriocitrin is metabolized by gut microbiota, and a chain of molecules such as eriodictyol, methy-eriodictyol, 3,4-dihydroxyhydrocinnamic acid (DHCA), and much more conjugated molecules. More in-depth studies are recommended to explore this drug for clinical trials.

The development and validation of an HPLC-MS/MS method for the determination of eriocitrin in rat plasma and its application to a pharmacokinetic study

Eriocitrin is one of the major active constituents of lemon fruit, and it possesses strong antioxidant, lipid-lowering, anticancer and anti-inflammatory activities and has long been used in food, beverages and wine.

A new voltammetry sensor platform for eriocitrin based on CoS2-MoS2-PDDA-GR nanocomposite

A novel electrochemically activated nanocomposite, CoS₂ Nanoparticles and MoS₂ Nanosheets decorated poly(diallyldimethylammonium chloride)-functionalized graphene (CoS₂-MoS₂-PDDA-GR), was successfully synthesized through a simple and low-cost method. X-ray diffraction (XRD), Transmission electron microscopy (TEM), Electrochemical impedance spectroscopy (EIS) and Cyclic voltammetry (CV) techniques were used to characterize the nanocomposites. Based on the CoS₂-MoS₂-PDDA-GR nanocomposite modified glassy carbon electrode, the electrochemical properties of eriocitrin were investigated in detail and a sensitive determinative method was established synchronously. Compared with others, this sensor exhibited larger effective surface area, more reactive site and excellent voltammetric response for eriocitrin. Under optimum conditions by DPV, the oxidation peak currents responded to eriocitrin linearly over a concentration range from 2.0 × 10^-9 to 1.0 × 10^-6 mol L^-1 with a detection limit of 6.7 × 10^-10 mol L^-1 (S/N = 3). In addition, this fabricated sensor was successfully applied to detect eriocitrin in real samples with satisfactory results.
