A standardised LC-UV-MS micro-scale method for screening of fungal metabolites and mycotoxins in culture extracts is presented. The paper includes data for detection and dereplication of >400 fungal metabolites to facilitate detection and identification when standards are not available. The data also shows the types of components that can be analysed by positive electrospray (ESI+) mass spectrometry (MS) along with common fragments and adducts of these, as well as giving suggestions on whether UV or ESI+ -MS methods should be used. Examples of dereplication of penitrems and macro-cyclic trichothecenes, and detection of several novel compounds are shown. This was done by UV spectroscopy combined with accurate mass determination of adduct and fragment ions obtained by high-resolution orthogonal time-of-flight MS. (C) 2003 Elsevier Science B.V.
