Abstract
Six mycotoxins, aflatoxins (AFB1, AFB2, AFG1, AFG2), cyclopiazonic acid (CA) and kojic acid (KA) which produced by Aspergillus flavus group species were analyzed by GC without chemical derivatization. The GC system contains fused silica capillary column (DB-5, 0.25mm i.d.×10m) and capillary on-column injector. Either FID or MS could be used as a detector. The analysis was highly reproducible and the detection limit of these mycotoxins by GC-FID were 1 ng for AFB1 and AFB2, 2 ng for AFG1 and AFG2, 0.5 ng for CA and 1 ng for KA.
