Acacia hybrid from plantation was divided into bark, sapwood and
heartwood. Each portion undergone Soxhlet extraction according to
ASTM D1108-96, D1107-96 and D1110-84 using different polarity
solvents; hexane, methanol and hot water. The crude extract of each
portion was analyzed to determine its chemical components of wood
extractives from the extraction solvents. Wood extractives covered
in this study were low molecular weight compounds; fatty acids,
sterols, glycerides and steryl ester. Gas chromatography analysis
was carried out for crude extract of hexane and methanol due to
these volatile solvents. Crude extract of hot water was analyzed by
High Performance Liquid Chromatography due to its non-volatility.
Results shown that total extractives analyzed by Gas chromatography
for methanol extract in heartwood was highest, 1.45 mg/g, followed
by bark and sapwood of 1.39 mg/g and 0.89 mg/g respectively. For
hot water extract, heartwood was found to have the most in total
extractives, 1.83 mg/g, followed by bark 1.26 mg/g and sapwood,
0.82 mg/g.
