Chlorinated bis(bibenzyls) of the bazzanine type were detected in crude bryophyte plant extracts of Bazzania trilobata from different locations using laser desorption/ionization time-of-flight (LDI-TOF) mass spectrometry without addition of an additional chemical matrix. The degree of chlorination c
The search for novel pharmacological tools in spider venoms involves the need for precise and reproducible species identification methods. As an addition to morphological analysis, we have developed venom fingerprinting by reversed-phase chromatography and matrix-assisted laser desorption/ionization
Crude ethanol extracts of leaves of Croton (Euphorbiaceae) species (C. hemiargyreus var. gymnodiscus, C. hemiargyreus var. hemiargyreus and C. echinocarpus) were analysed using on-column injection high temperature gas chromatography coupled with mass spectrometry. Several isoquinoline alkaloids were
Multi-stage mass spectrometry (MSn) (up to n = 6) using a combination of electrospray ionization with a quadrupole ion trap was applied to the gas-phase isolation and direct structure elucidation of a complicated surfactant molecule in a crude product extract.
