[Minor alkaloids from the fungus Penicillium roquefortii Thom 1906].

New spatial of clavine alkaloids, distinguished by low chromatographical mobility, have been isolated from the collection and mutant strain of Penicillium roquefortii, in addition to alkaloids roquefortine, 3,12-dihydroroquefortine, isofumigaclavines A and B, festuclavine, and chanoclavine-I, characteristic of this fungal species. In has been shown that the collection strain produces isomers of agroclavine and epoxyagroclavine, and the mutant strain produces isomers of fumigaclavines A and B, festuclavine, and chanoclavine.
