Componentes químicos de la madera de cinco especies de pino del municipio de Morelia, Michoacán

Abstract: 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 cen… Show more

“…These satisfy this parameter and concur with figures reported in previous studies, which indicate a range of 0.28-1.25%. In fact, these values surpass those determined elsewhere [51,[55][56][57][58]. For the case of the wood used in our work, the results for ash content satisfy the established standard.…”

“…The ranges registered both for branches as twigs of the species studied included the highest value published by Bernabé et al [56] for pines, in wood of Pinus leiophylla (28.5%) and by Rutiaga [57] for the heartwood of Pinus pseudostrobus (27.6%).…”

“…It is important to note that heavy metals were not found in the studied samples. The high concentration of inorganic substances (Table 2) Alkali solubility ranged from 48.9 to 55.9 wt.%, which is higher than those reported for wood species (Bernabé-Santiago et al 2013). It is known that hot alkali solution extracts low-molecular-weight carbohydrates consisting mainly of hemicellulose and degraded cellulose and this treatment can influence the natural durability of lignocellulosic materials (TAPPI T212 om-98 2000).…”
