J. Planar Chromatogr. 6. 476-480 (1993). TLC of fumonisin B1 and B2 on silica (prewashed) with 1-butanol - acetic acid - water 20:10:10 to a distance of 8 cm (first development); after careful drying, the bottom edge was cut off 1 cm below the Rf of FB1, the plate was then developed to the top of the plate (6 cm) in the same direction with chloroform - methanol - acetic acid 55:36:8:1. Visualization by spraying with 5.5% p-anisaldehyde and heating at 110 °C for 10 min. Quantification by densitometry in the absorbance mode. Detection limit 51.1 ng for standards. 100 ng for extracts; limit of quantification 100 mg/kg without purification and 5 ppm after purification.

Analytical Chem. 68, 3885-3891 (1996). Investigation of the use of a scientifically operated charge-coupled device (CCD) for the detection and quantification of aflatoxins on a HPTLC plate. A nebulizer-based sample application system was utilized to transfer the sample quantitatively onto the HPTLC plate without disturbing the sorbent layer. Fluorescence excitation of the aflatoxins was accomplished with an ultraviolet transilluminator, which caused the analytes of interest to emit in the blue-green portion of the visible spectrum. The dynamic range, sensitivity, accuracy, and precision of the system were evaluated. Detection limits of the aflatoxins were determined to be in the low picogram range.

J. Planar Chromatogr. 12, 383-387 (1999). OPLC of aflatoxins B1, B2, G1 and G2 on TLC and HPTLC silica gel with chloroform - ethyl acetate - tetrahydrofuran 10:15:1. Quantitative determination by densitometry at 365 resp. 436 nm.

Proc. Intern. Symp. on Planar Separations Plan. Chrom. 319-327 (2003). OPLC of aflatoxins B1, B2, G1, G2 on silica gel, prewashed with methanol - acetone 1:9, with chloroform - acetone 22:3. Bioautography after drying by dipping in culture media containing Pseudomonas savastanoi pv. phaseolicola bacteria cells and incubation for 18 h at 100% rel. humidity at 28°C. For visualization bioautograms were stained with an aqueous solution of MTT (in 100 mL water 80 mg MTT and 100 mg Triton X-100 solution).
