METABOLITE PROFILES OF COMMON STEMPHYLIUM SPECIES

Thirty-three isolates of Stemphylium spp. have been analysed for their metabolite profiles. Five metabolites, stemphylin, stemphyloxin II, s temphyperylenol, stemphol and a stemphol related compound, have been d etected by high-performance liquid chromatography and thin-layer chrom atography and identified by their chromatographic and spectroscopic da ta (R(f) values, reflectance spectrum, retention index and ultraviolet spectrum). These metabolites have been used for the chemotaxonomical characterization of Stemphylium botryosum, S. herbarum, S. alfalfae, S . majusculum, S. sarciniforme, S. vesicarium, Pleospora herbarum and P . tarda.
