Wood samples from four forest species were studied in terms of their structural chemical composition, basic chemical procedures and agreements with their ASTX technical standards. Tests were performed for each species from samples of kiln dried sawdust (dry anhydrous) prior to extraction with neutral solvents of the so-called extractable components. Average records of the four species were obtained with three replicates per species, such as cellulose, pinhole, lignin and centimeters. The values obtained from the four species are compared with each other and with species from which wood is obtained pulp industrially. There were significant differences in the content of cellulose contained in four species studied, registering values (66.7%) of the species Cupina Cineria, compared to the rest of species. Acalypha macrostachya, cecropia pilystachya and ochroma pyramidale. To complete the study, tests with xx cm specimens were carried out. Of the four species with the objective of determining the basic density and anhydrous density. Obtaining values of basic density from gf / cm (pyramidal Ochroma) to 0.592 g / cm3 (cupania cineria). The results obtained from the structural chemical composition, will allow us to know the fibrous potential of the studied species and give them greater use as in the paper industry. The research gives us percentage values of extractives ranging from 12 to 2.6% in alcohol and from 3.0 to 2.9% of distilled water, cellulose (44.4 - 56.7)%, Ligine (8.2 - 10.10%), ashes (0.9 - 1.20%) a Basic density (0.143 - 0.592 g / cm3). Ranges that are within the values realized by other investigations in hardwoods
