identified headspace constituent of Penicilliumroqueforti. Feeding experiments with 13C‐labeled mevalonolactone isotopomers demonstrated that oxidation at C12 and an isomerization of the C11C12 to a C7C11 double bond must occur independently and not via a C7‐C11‐C12 allyl radical in one step. Feeding with (11,12,13‐13C3)‐7‐epi‐neopetasone resulted in labelling of the PRtoxin, thus establishing this compound

were analyzed by gas chromatography–mass spectrometry (GC-MS) and quantified accurately by gaschromatography with a flame ionization detector (GC-FID), using an internal reference and predicted response factors. Since a significant number of components of this extract remained non-identified after the initial GC-MS analysis of the whole extract, its fractionation by chromatography on silica gel helped
