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.
