- Composición química de la madera de Tabebuia impetiginosa (Mart. Ex DC) Standley proveniente de la comunidad rural Ocho Hermanos, Municipalidad El Carmen Rivero Torrez, Departamento de Santa Cruz David Fernando Urrelo Laura Leal Carmen Bozo Química The chemical composition of Tabebuia impetiginosa (Mart. ex DC) Standley, was characterized by applying standard analytical methodologies (TAPPI). The species also known as Tajibo Morado was coll ected in the rural community “O cho Hermanos” from the “El Carmen Rivero Torrez” count y of the Santa Cruz Department in Bolivia. Three samples of 30 cm long were extracted for each tree affording a total of n ine wood slices. The obtained results show an average of 45.22% of cellulose, 32.07% of lignine and 22.69% of hemicellulose, in the etanol - benzene extracts with 2.27%. The evaluation of the moisture contents gave an avera ge of 15.44%; the pH was 5.22. T he ashes afforded an average of 1.31% and the minerals were estimated as: phosphor 0.011%, calcium 0.22%, magnesium 0.12%, potasium 0.013%, sodium 0.060%. The nitrogen determination afforded the average value of 0.47%. F inally , the proteins were in an average of 2.96%. As a conclusion we can infer that the species Tabebuia impetiginosa (Mart. ex DC) Standley has an important potential as a source for the exploitation of wood waste, as well as for the obtaining of: pellets, briquettes, bioethanol, cattle food, carbon, adhesive and other derivatives. 2016 artículo científico 0250-5460 https://www.redalyc.org/articulo.oa?id=426347540001 es http://www.redalyc.org/revista.oa?id=4263 Revista Boliviana de Química application/pdf Universidad Mayor de San Andrés Revista Boliviana de Química (Estado Plurinacional de Bolivia) Num.3 Vol.33
