ABSTRACTÂ
The selection of bamboo species for various applications in the chemical and biochemical related industry is related to the chemical composition. This research was carried out to study the major chemical compositions of bamboo culms grown around Assosa town in Ethiopia. Lowland bamboo (Oxytenanthera abyssinica) samples were harvested, sorted, dried, milled using Wiley Mill, sieved and all chemical characteristics were determined in accordance with the standards outlined in ASTM except Kurchner-Hoffer and Alkali extraction method for cellulose and hemicellose determination, respectively. From the study it showed that the average results of the main chemical composition (Cellulose, Hemicelluloses and Lignin) were 52.06, 16.90 and 22.47%, respectively. The Ash content of Oxytenanthera abyssinica was 5.30% while the extractives content (Hot-water & Alcohol-toluene solubility) was 6.80 and 5.60%, respectively.
