✦ Synopsis

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 could be identified by the characteristic isotope patterns. These results suggest that these chlorinated compounds are not artefacts of an incidental occurrence, or of the sample preparation, but are genuine natural products produced by the liverwort or by an endosymbiotic metabolism.
