| description | A chemical analysis was performed to determine the major chemical components of five pinespecies in the municipality of Morelia, Michoacán. The pine species studied were: Pinus leiophylla, P.michoacana var. cornuta, P. montezumae, P. oocarpa and P. teocote. The pH value, ash, ash analysis,extractives, holocellulose, lignin and tannins content was determined for each pine species. The resultswere in the range of 4,0 to 4,4 for pH, 0,3% ash in all species (calcium and potassium in higher concentration),17,9% to 25,4% for soda solubility, 7,6% to 8,2% total extractives, 68,1% to 74,7% for holocellulose,24% to 28,5% for lignin and 0,07% to 0,12% for tannins. Through the applied extraction thewood solubility followed the sequence: water > ciclohexan > aceton > methanol. Analysis of variance ofthe data showed that pH, soda solubility, holocellulose, lignin and tannins did vary among pine species(P < 0,05). |

Se realizó un análisis para determinar los principales componentes químicos de la madera decinco especies de pino procedentes del municipio de Morelia, Michoacán. Las especies estudiadasfueron Pinus leiophylla, P. michoacana var. cornuta, P. montezumae, P. oocarpa y P. teocote. En esteestudio se determinó en la madera de cada especie el pH, las cenizas, el análisis de las cenizas, lassustancias extraíbles, la holocelulosa, la lignina y los taninos. Los resultados encontrados fueron: pHde 4,0 a 4,4; 0,3% de cenizas, con mayor concentración de calcio, potasio y magnesio, 17,9% a 25,4%de solubilidad en sosa; 7,6% a 8,2% de extraíbles totales, en la extracción secuencial, la mayor solubilidadse obtuvo con agua caliente, seguido en proporciones similares con ciclohexano, acetona y metanol;68,1% a 74,7% de holocelulosa, 24,0% a 28,5% de lignina y 0,07% a 0,12% para taninos. Lasolubilidad de la madera para las extracciones siguió la secuencia agua > ciclohexano > acetona >metanol. El pH, la solubilidad a la sosa, la holocelulosa y la lignina presentaron una variación estadísticasignificativa (P < 0,05) entre especies.
