Mass spectrometry (MS) is widely used for the structural elucidation of compounds in a vast variety of scientific research. Unfortunately, many methods that aim to predict mass spectra cannot often elucidate the complete ...

Polyphenole sind Sekundärmetaboliten und meist Minorkomponenten von Pflanzen und spielen eine Rolle unter anderem als UV- und Fraßschutz, Schutz vor Pilzbefall und als Allelochemikalien. Die Lebensmittelqualität und ......
Optimized Analysis of Flavonoids by HPLC-MS
Polyphenols are secondary metabolites found usually as minor constituents in plants and serve as allelo-chemicals and as a protection against ultraviolet ......

The first part of this thesis focuses on the mechanistic studies of an intermolecular cyclization reaction between an α,β-unsaturated aldehyde and an electron deficient primary alkyne to a cyclopentene carbaldehyde. Based ......

Studies aimed at understanding the molecular basis of the desiccation tolerance in angiosperms have mainly focused on the South African plant Craterostigma plantagineum. C. plantagineum belongs to the Linderniaceae family, ...

The first part of this thesis focuses on mechanistic studies of two L-proline catalyzed reactions with electrospray ionization mass spectrometry. The second part describes mass spectrometric analyses of fossils, dinosaur ...
