The chemical components of the oil palm trunks fibers before
and after water treatments were investigated. Preparations of
extractive free samples were conducted according to TAPPI 264 cm-
97 (TAPPI, 1997) with a modification ofthe solvent ethanol-toluene
ratio of 2:1. Holocellulose content was done based on the method
of Wise, Murphy, and D’Addieco (1946). The cellulose content was
extracted from the percentage of holocellulose with 17.5% sodium
hydroxide. Lignin content of the samples was analyzed according
to TAPPI 222 om-02 (TAPPI, 2002). Total starch content was carried
out using a total starch kit manufactured by Megazyme International
Ltd, Bray, Ireland. Measurement was conducted in triplicate,
and the recorded data were found to be reproducible.
