AbstractIn this paper we applied thermally assisted hydrolysis and methylation to a soil humic acid (HA) and their polyacrylamide gel electrophoresis (PAGE) fractions. The data indicates that PAGE fractionation of HA produces selectively enriched humic fractions in terms of major structural components (e.g. fatty acids, lignin units, etc.). Lignin components were mainly found in fraction b (medium electrophoretic mobility) of HA. Plant fatty acids were mainly distributed in fraction a (no electrophoretic mobility), and microbial lipids were distributed in all fractions, but the higher relative amounts appeared primarily associated with fractions b and c+d (high electrophoretic mobility).
