Petroleum ether soluble part (fraction γ<SUB>1</SUB>) and petroleum ether insolu-ble, chloroform soluble part (fraction γ<SUB>2</SUB> ) of pyridine extract of Nakayama lignite were analyzed by <SUP>13</SUP>C-and <SUP>1</SUP>H-NMR spectra.The average molecular structure parameters of the fractions γ<SUB>1</SUB> and γ<SUB>2</SUB> were calculated from the results of quantitative <SUP>13</SUP>C-NMR spectra obtained by the gated decoupling with the relaxation reagent, <SUP>1</SUP>H-NMR spectra, elementary analysis and average molecular weight.<BR>The average molecular structure of aromatic rings in the fraction γ<SUB>1</SUB> consists of ben-zene ring and quinone ring, and that of the fraction γ<SUB>2</SUB> consists of one benzene ring and aromatic rings such as naphthalene.The nonbridge aromatic ring carbons of 50-60 percent in the frac-tions γ<SUB>1</SUB> and γ<SUB>2</SUB> are substituted by alkyl groups.
