title: Isolation of secondary metabolites of Aspergillus ochraceus by HPLC.
abstract: A method is described for the isolation and purification of ochratoxin A, ochratoxin B, ochratoxin ß mellein, 4-hydroxymellein and penicillic acid produced byAspergillus ochraceus in a synthetic liquid medium. Ochratoxin α, which was not found in the culture medium, was obtained by acid hydrolysis of ochratoxin A. A high pressure liquid Chromatograph equipped with Lichrosorb 100 and Lichrosorb RP-18 columns and UV and/or Refractive Index detectors was used.
