TEAK is one of the most valuable timber widely used in the world. It is prized for its colour, aesthetic and natural durability. A variability has been observed in wood properties with consequences for forest managers and end-users. Determining some attributes for earlier characterization of wood quality may be useful. Wood colour is an important criterion of wood quality and depends on the chemical components of wood (HoN and MINEMURA, 2001). We assessed the use of colorimetry to determine the content of phenolics in the wood.
