RUTIAGA-QUINONES, J. G.; PEDRAZA-BUCIO, F. E. y LOPEZ-ALBARRAN, P.. Main chemical components of Dalbergia granadillo Pittier and Platymiscium lasiocarpum Sandw wood. Rev. Chapingo ser. cienc. for. ambient [online]. 2010, vol.16, n.2, pp.179-186. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2010.04.023.
A chemical analysis of the wood (heartwood, transition zone and sapwood) of two tropical species (Dalbergia granadillo and Platymiscium lasiocarpum) was conducted according to ASTM standards. The chemical components determined were: ash, extractives (ethanol-benzene, hot water and water at ambient temperature), lignin and holocellulose. The amounts of chemical compounds found in the wood samples ranged as follows: ash (0.62 to 1.84 %), total solubility (10.19 to 33.35 %), lignin (25.24 to 27.24 %) and holocellulose (49.24 to 55.25 %). The statistical analysis of variance of the results indicated that the amount of chemical components is statistically different (P<0.05) between the two species and the three types of wood.
