AbstractΓThree new metabolites, anthrasteroids, have been isolated from the mycelia of a hybrid strain, KO 0231, prepared by cell fusion technique using Penicillium citreo-viride IFO 6200 and 4692. Their structures were determined based on their spectral data. Furthermore, these natural products wer
Two new metabolites, citreo-y-pyrone and citreothiopyrane A, with interesting biological activity have been isolated from the mycelia of hybrid strains KO 0201 and 0211 derived from Penicillium citreo-viride B. IFO 6200 and 4692. Their structures have been elucidated based on their spectral data. In
