| description | In this study, the main wood chemical composition of Ceiba pentandra, Hevea brasiliensis and Ochroma pyramidale was determined with the aim of providing knowledge on wood chemistry of tropical species and information to explore possible chemical applications. For this, the contents of ash, ethanol-benzene extracts, ethanol extracts, lignin, holocellulose, cellulose and hemicelluloses were quantified in the stem at three height levels (bottom, middle, and top). Results of the chemical analysis showed that concentrations of the determined constituents varied within the stem of the individual wood species and also among species. The average amount of chemical compounds among the species was 0,44% - 1,64% for ash; 1,42% - 3,42% for ethanol-benzene extracts; 1,88% - 5,07% for ethanol extracts; 3,83% - 8,46% for total extracts; 19,71% - 26,83% for lignin, 77,73% - 83,52% for holocellulose; 39,67% - 47,63% for α-cellulose and 33,79% - 42,85% for hemicelluloses. According to the obtained contents of lignin, α-cellulose and hemicelluloses, the wood of these species could be used in pulping and bioconversion processes. |

En este estudio se determinó la composición química principal de madera de Ceiba pentandra, Hevea brasiliensis y Ochroma pyramidale con el objetivo de proporcionar conocimientos sobre química de la madera de especies tropicales e información para explorar posibles aplicaciones químicas. Para esto, se cuantificaron los contenidos de cenizas, extractos de etanol-benceno, extractos de etanol, lignina, holocelulosa, α-celulosa y hemicelulosas en el fuste a tres niveles de altura (inferior, medio y superior). Los resultados del análisis químico mostraron que las concentraciones de los constituyentes determinados variaron dentro del fuste de las especies leñosas individuales y también entre las especies. La cantidad promedio de los compuestos químicos entre las especies fue de 0,44% a 1,64% para las cenizas; 1,42% a 3,42% para los extractos en etanol-benceno; 1,88% a 5,07% para los extractos en etanol; 3,83% a 8,46% para los extractos totales; de 19,71% a 26,83% para lignina, 77,73% - 83,52% para holocelulosa; 39,67% - 47,63% α-celulosa y 33,79% a 42,85% para hemicelulosas. De acuerdo con los contenidos obtenidos de lignina, α-celulosa y hemicelulosas, la madera de estas especies podría ser utilizada en los procesos de pulpeo y de bioconversión.
