Fractionation of raw and methylated fulvic acids from lignite by thin-layer chromatography

Raw and methylated fulvic acids from lignite were subjected to thin-layer chromatography on silica gel, using the simplex method to optimize the eluant composition. The chromatograms did not show definite spots, but a continuous profile that could be resolved with a densitometer. Preparative TLC was...
