Synopsis:Wood (tree) has been used for structural material of house and furniture, for raw material of paper and rayon and for drugs including anti-aids and anti-cancer from ancient. Wood is even promised for our future materials since it has reproducibility by tree plantation and creation of relaxing environment for human. These features depend on both wood chemical and anatomical traits and the characterization of wood is demanded. However, wood is consisted of a few hundreds of compounds including cross-linked polymers and has nanometer order structure (oriented cellulose microfibrills) with meter order one (vessels for water conduction from root to top of the tree). These make the characterization complicated and lengthy. In this review, the characterization of wood as a natural complex material was described for the analysis by near infrared FT-Raman spectroscopy as a rapid, non-destructive and quantitative analytical method with our experience including the instrumental improvement for quantification.
