Large peaks of TMSi protons derived from hydroxyl groups appeared in high magnetic shielded ranges, and enabled to determine hydroxyl protons which were generally difficult to analyse by NMR. Some chemical properties such as distribution of molecular size and chemical analysis of three kinds of MWL's were also examined. The molecular wight (Mn) of the MWL's of Metasequoia, beech and bamboo were 2610, 2700 and 1740, respectively.
