Research Abstract	This study aimed to establish an experimental methodology to analyze diversity of hydrolysates and metabolites present in the digestive systems of termites with the aid of one(^1H) and two(^1H,^<13> C) dimensional NMR(nuclear magnetic resonance) analyses. The analysis of the gut contents in the damp-wood termite Hodotermopsis sjostedti revealed the presence of diverse metabolites for the first time. In addition, possible involvements of intestinal bacteria in cellulolysis and amino acid supplement were suggested by the present study.
