title: Stemphyltoxin III from Alternaria alternata.
abstract: Stemphyltoxin III, (6aR*, 6bS*, 7R*, 8R*)-3,6a, 10-trihydroxy-4,9-dioxo-4,6a,6b,7,8,9-hexahydro-7,8-epoxyperylene, a known metabolite of Stemphylium botryosum var. lactucum, has been identified as a mutagenic metabolite of Alternaria alternata by spectroscopic studies. The 13C-nmr spectral data, which were not reported previously, are presented.
