The δ-lactone of ocarboxyphenyl-glyceric acid was used as the model substance of peat humic acid.   As a result,the carboxyl groups in peat humic acid were converted to the primary amide,the lactam con6gurations vvere formed from the a-lactone,and part of the aromatic hydroxy groups were converted to the amine. Continual existence of other N-containing groups such as ammonium, nitrile,amidine,imino group and iso-indol configuration was not found.   A schematic representation of the above reaction is shown in figure 3.}, pages = {131--138}, title = {泥炭フミン酸とアンモニアとの反応}, volume = {6}, year = {1975} }
