“…However, the fluorometric method is sample-consuming and lacks selectivity, while chromatography requires sample pretreatment, long analysis times and high costs, preventing them from being applied in routine analysis [5]. Electrochemical methods, with the advantages of rapidity and costeffectiveness, have been widely employed for the detection of highly electroactive dopamine.…”

A sensitive and selective electrochemical method for the determination of dopamine using a combined electropolymerized permselective film of polytyramine and polypyrrole‐1‐propionic acid on a glassy carbon (GC) electrode was developed. The formation of a “layer‐by‐layer” film has allowed for selective detection of dopamine in the presence of 3,4‐dihydroxyphenylalanine (L‐DOPA), DOPAC, ascorbic acid, uric acid, epinephrine and norepinephrine. The modified electrodes exhibited a detection limit of 100 nM with linearity ranging from 5×10−6 to 5×10−5 M. No cleaning step was required during the course of repeated measurement.

“…The steamed ginseng has a stiff texture, which not only protects the effective ingredients but also produces new constituents (Kim et al 2000). Major ginsenosides of red ginseng saponin extract include less polar red ginseng-unique saponins Rg3, Rk1 and Rg5 in a HPLC analysis (Kim et al 2008 As supplementation with red ginseng is believed to improve health, numerous studies have been conducted to validate its beneficial effects. They demonstrate that red ginseng has anti-inflammatory (Jung et al 2012), antidiabetic , anticancer and arthritis-ameliorating effects (Jhun et al 2014).…”

Two new dammarane-type triterpene sapogenins were isolated from the Chinese red ginseng. The new sapogenins were named as 24,26-dihydroxy-panaxdiol (1) and 24-hydroxy-panaxdiol (2). Their structures were elucidated by the combined analysis of NMR and mass spectrometry as 20(S),25(R)-epoxydammarane-3β,12β,24β,26-tetraol (1) and 20(S),25-epoxydammarane-3β,12β,24α-triol (2). The complete signal assignments of the two compounds were carried out by 2D NMR spectral and NOE differential spectroscopy analysis.

“…It plays an important role in the function of central nervous, renal, hormonal and cardiovascular systems. Low levels of DA are related to neurological disorders such as schizophrenia, Parkinson’s disease and to HIV infection 2. Therefore, physiological determination of dopamine with high sensitivity and selectivity is great clinical significance.…”

This work presents the fabrication of Nafion (Nf) or Nafion/Multiwalled Carbon Nanotubes (Nf/MWCNTs) modified gold microarray (Au‐µA) and macro‐(Au‐M)electrode biosensors. The surface morphologies of the above electrodes were examined using SEM. The catalytic properties of the above electrodes towards dopamine were tested using square wave voltammetric technique. The Nf/MWCNT/Au‐µA electrode exhibited a wide range (0.1–1000 nM) of linearity among the other electrodes. The LOD of Nf/MWCNT/Au‐µA electrode was 50 pM for dopamine in the presence of 5000 µM ascorbic acid. Therefore, the Nf/MWCNT/Au‐µA biosensor was applied for the determination of dopamine in human serum.
