Abstract Partial resolution of aflatoxins B1, B2, G1, G2, and P1 was achieved by high-speed liquid chromatography (HSLC) on a porous layer silica adsorbent, using chloroform-isooctane as the eluting solvent and a 254 nm UV monitor for detection. The resolution was somewhat less than, although comparable with, that obtained by thin layer chromatography, using Adsorbosil-1 adsorbent and fluorodensitometric detection. The HSLC response to B1 and G1 was linear in the 400–3000 ng range, allowing application of the technique to the quantitative analysis of B1 and G1 in crude extracts of Aspergillus parasiticus cultures. The coefficients of variation (precision) were 4.2% for B1 and 23.2% for G1 in a series of 4 replicate injections. The advantages and limitations of the technique for quantitative analysis and isolation are compared with those of more conventional chromatographic methods.
