Abstract

The mixture of steroid metabolites of the phytopathogenic fungusV. dahliae have been studied by high- and low-resolution mass spectrometry, metastable defocusing, and the direct analysis of daughter ions (DADI). On the basis of the analysis of the spectral results obtained for the mixtures themselves and for the products of their tosylation the presence in the samples studied of mixtures of β-sitosterol, stigmasterol, and cholesterol has been established. Probable structures have been proposed for the components of the mixture with m/z values of the molecular ions of 426, 424, and 412.
