A new biflavonoid from Solanum dulcamara L. and investigation of anti-hyperglycaemic activity of its fruit extract
(Taylor & Francis Ltd, 2015)
A new biflavone, 6,2 ',3 '',5 '',4'-pentahydroxy-3,7 ''-biflavone, has been isolated from the fruits of Solanum dulcamara L., in addition to two known compounds, beta-sitosterol and stigmasterol. Their structures were ...
Voltammetric behavior of lercanidipine and anodic adsorptive stripping voltammetric method for assay in pharmaceutical dosage forms and biological fluids
(Bulgarian Acad Science, 2014)
Electrochemistry of lercanidipine (LCN) was investigated and its optimal conditions were evaluated based on the irreversible and diffusion-controlled electrochemical oxidation signal (+ 0.93 V) of a carbon paste electrode ...
Validated spectrofluorimetric method for the determination of tamsulosin in spiked human urine, pure and pharmaceutical preparations
(Wiley-Blackwell, 2014)
A novel, sensitive and selective spectrofluorimetric method was developed for the determination of tamsulosin in spiked human urine and pharmaceutical preparations. The proposed method is based on the reaction of tamsulosin ...
Influence of Se/N Codoping on the Structural, Optical, Electronic and Photocatalytic Properties of TiO2
(Mdpi Ag, 2017)
Se4+ and N3- ions were used as codopants to enhance the photocatalytic activity of TiO2 under sunlight irradiation. The Se/N codoped photocatalysts were prepared through a simple wet-impregnation method followed by heat ...

(Pergamon-Elsevier Science Ltd, 2017)
The synthesis, characterization and biological studies of three novel antimony(III) complexes (SbX3, X = Cl and Br) with N-substituted thioureas; N,N-dimethylthiourea (DMTU) and N,N-diethylthiourea (DETU) of formulae ...
Reduced graphene oxide/Titanium oxide nanocomposite synthesis via microwave-assisted method and supercapacitor behaviors
(Elsevier Science Sa, 2017)
In this paper, graphene oxide (GO) was firstly synthesized by modification of Hummers method from the literature. Secondly, reduced graphene oxide (rGO)/Titanium oxide (TiO2) nanocomposites were synthesized with different ...
Quantification of Trypsin Activity by a New Biosensing System Based on the Enzymatic Degradation and the Destructive Nature of Trypsin
(Springer, 2017)
Trypsin is an enzyme that is included in the hydrolysis class of enzymes. Trypsin catalyzes the cleavage of proteins from a serine residue and is found in the digestive system of vertebrates. The cystic fibrosis, which is ...
