Jean-Pierre Mufusama,Jean-Pierre Mufusama,Karine Ndjoko Ioset,Karine Ndjoko Ioset,Doris Feineis,Ludwig Hoellein,Ulrike Holzgrabe,Gerhard Bringmann +7 more
TL;DR: The study shows the necessity to equip developing countries with modern techniques such as HPLC, which, if combined with affordable techniques like TLC, could provide a pertinent analytical strategy to combat drug counterfeiting and poor manufacturing.
Reference EntryDOI
Quantitative NMR Spectroscopy in Pharmaceutical R&D
TL;DR: In this paper, the acquisition and processing parameters have to be set carefully for quantification purposes, and special attention has to be paid to the complete T1 relaxation, which can be achieved by either internal or external standards.
Journal ArticleDOI
Improving anti-trypanosomal activity of alkamides isolated from Achillea fragrantissima.
Joseph Skaf,Omar Hamarsheh,Michael Berninger,Srikkanth Balasubramanian,Tobias A. Oelschlaeger,Ulrike Holzgrabe +5 more
TL;DR: In previous studies the aerial parts of Achillea fragrantissima were found to have substantial antileishmanial and antitrypanosomal activity and a bioassay-guided fractionation of a dichloromethane extract yielded the isolation of the essential anti-trypanosome compounds of the plant.
Journal ArticleDOI
Analysis of the molecular size distribution of polyethylene glycols by CE-UV versus HPLC with evaporative light scattering detection.
Daniela Brinz,Ulrike Holzgrabe +1 more
TL;DR: An HPLC method with evaporative light scattering detection has been established and was successfully applied to the analysis of underivatized PEG 400, 1000 and 1500, successfully comparing the capillary zone electrophoresis results.
