title: Psychrophilin B and C: cyclic nitropeptides from the psychrotolerant fungus Penicillium rivulum.
abstract: Psychrophilins B (1) and C (2), two new cyclic nitropeptides, have been isolated from the psychrotolerant, new species Penicillium rivulum Frisvad. The nitropeptides were isolated by high-speed countercurrent chromatography (HSCCC) and HPLC using UV-guided fractionation of the organic extract.
