    Description

    A comparative study was done on Liquidambar Orientalis Mill heartwood extractive samples. These extractives were collected from wood decay specimens. The objective of the study was to determine the chemical composition of the extractives remaining after exposure to brown rot fungi Tyromyces Palustris and white rot fungi Trametes Vericolor. All samples were extracted according to TAPPI Standard T-204. Samples were put through two different solvent systems and characterized by analytical techniques for any changes in chemical and morphological properties. The extracted chemicals collected were control 13%, T. versicolor 18% and T. palustris 69%. The polar composition remains higher than the nonpolar composition as is usually observed in hardwoods.
