          Abstract

          Se realizó un análisis químico para determinar los principales componentes presentes en la madera (albura y duramen) y corteza de Haematoxylon brasiletto Karsten (palo de Brasil). En este estudio se determinó el contenido de cenizas y se hizo el análisis de las cenizas, las sustancias extraíbles, la holocelulosa y la lignina. Se encontró que los componentes químicos variaron como sigue: cenizas de 2,88% a 18,20%, extraíbles totales de 9,84% a 29,70%, holocelulosa de 44,82% a 66,20% y lignina de 25,37% a 31,70%. El análisis de varianza de los resultados, indicó que la cantidad de componentes químicos es diferente estadísticamente (P<0,01) entre los tres tipos de material, a excepción de los extraíbles solubles en ciclohexano y la lignina.

          Translated abstract

          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.
