artemether/dichloromethane

A rapid, selective, sensitive and reproducible HPLC with reductive electrochemical detection for quantitative determination of artemether (ART) and its plasma metabolite, dihydroartemisinin (DHA: alpha and beta isomers) in plasma is described. The procedure involved the extraction of ART, DHA and

A sensitive and selective reversed-phase high-performance liquid chromatographic method for the determination of artemether and its major metabolite dihydroartemisinin in plasma has been developed. It involves extraction of plasma with dichloromethane, solid-phase separation of the two analytes and

TLC scanning technique was found to have good specificity for studying the absorption and distribution of artemether in rats. Plasma or tissue homogenates 0.2-1.0 ml were placed in glass extraction tubes and water was added to make 1.0 ml. Each sample was extracted 3 times with 4 ml mixed organic

Artemisinin is extracted from Artemisia annua, a shrub also known as sweet wormwood that was used in traditional medicine in Asia for more than 1500 years. Recent studies in numerous malarious zones have demonstrated the effectiveness of artemisinin and have reported no evidence of the resistance

β-artemether (ARM) is a widely used anti-malarial drug isolated from the Chinese antimalarial plant, Artemisia annua. The solvent effects on crystal habits and dissolution of ARM were thoroughly investigated and discussed herein. The ARM was recrystallized in nine different solvents of varied
