AVILA-CALDERON, Luz Elena A.  and  RUTIAGA-QUINONES, José Guadalupe. Chemical components of the wood and bark of Haematoxylum brasiletto Karsten (Leguminosae). Madera bosques [online]. 2014, vol.20, n.2, pp.153-158. ISSN 2448-7597.

A chemical analysis was performed on the sapwood, heartwood and bark of Haematoxylon brasiletto Karsten (palo de brasil) to identify its main chemical components. Ash, ash analysis, extractives, holocellulose and lignin content were determined. The results ranged of 2,88% to 18,20% for ash, 9,84% to 29,70% total extractives, 44,82% to 66,20% for holocellulose and 25,37% to 31,70% for lignin. The variance analysis of the results indicated that the amount of chemical components is statistically different (P<0,01) between types of wood and bark except cyclohexane extractives and lignin.

Keywords : ash; extractives; holocellulose; lignin; palo de Brasil.
