Background and objectives: The aerial parts of Artemisia marschalliana Sprengel as an indigenous species of genus Artemisia in the East Azerbaijan province of Iran, was subjected to phytochemical analysis, as well asanti-proliferative, free-radical-scavenging and anti-malarialactivities. Methods: The chemical composition of the essential oil o...

valproic acid (vpa) is one of the mostly used antiepileptic drugs that may have some side effects so, it is highly recommended to evaluate its serum concentrations. the aim of this study was to develop a simple, fast and economic method using gas-chromatography equipped with flame ionization detector (gc/fid) and vpa analysis. to do this, 200 µl of serum was mixed with an aliquot of caproic aci...

the our main goal of the present research is evaluating the performance of mno2 nanoparticles-agx zeolite composite as a novel adsorbent catalyst for the decontamination reactions of two most known sulfur mustard simulants; 2-chloroethyl phenyl sulfide (2-ceps), 2-chloroethyl ethyl sulfide (2-cees) at room temperature and monitoring by gas chromatography flame ionization detector (gc-fid) and g...

Cassia singueana (Delile) Lock from the family Fabaceae is a well-known medicinal plant that grows abundantly in Nigeria and other African countries, and has long been used in the treatment of various ailments including malaria and other infectious diseases. The present study aimed at  assessing the composition, and bioactivity of the essential oil of the flowers of C. singueana collected from ...

Matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS) has been applied for the first time to the analysis of the sucrose esters from the surface of Nicotiana L. leaves. The profiles obtained for the model plant N. tabacum were similar to those from the gas chromatography-flame ionization detector (GC-FID) analysis. The most reproducible results were obtaine...
