摘要: PR toxin is a secondary metabolite of the fungus Penicillium roqueforti. It lethal to rats, mice, and cats. Usually, amount in culture medium decreases from its maximum on day 15 zero within 3 4 days. We found that two were metabolites produced this while production was decreasing. isolated purified compounds pure colorless crystalline form. On basis elemental analysis mass, 1H 13C nuclear magnetic resonance, infrared, UV spectroscopies, identified as PR-imine (C17H21O5N) PR-amide (C17H21O6N). The structures both (C17H20O6) closely related, peak appeared earlier than those PR-amide. Moreover, transformed when incubated with given day. Thus, we propose degraded into P.
