Comparison between Different Components of Some Available Hardwood and Softwood in Bangladesh
Journal Title: IOSR Journal of Biotechnology and Biochemistry (IOSR-JBB - Year 2018, Vol 4, Issue 1
Abstract
This research was conducted to examine comparison between hardwood and softwood components. Cellulose, hemicellulose and lignin are major constituents for both hardwood and softwood. Depending on these constituents wood’s application varies. In this study we examined 10 important wood samples (5 are hardwoods & 5 are softwoods) which are mostly available in Bangladesh. The wood samples were tested in some standard chemical methods, whose samples were dewaxed and depectinised, then the lignin content was measured (mainly using H2SO4). After the removal of the lignin, two other mains components α-cellulose and hemicelluloses were measured. The average components values are 40-50% cellulose, 15-40% hemicelluloses and 18-25% lignin for hardwoods. On the other hand, the average components values are 40-45% cellulose, 24- 37% hemicellulose and 25-30% lignin for softwoods.According to their lingo-cellulosic contents they can convert into various useful products. Also by these constituents of hardwood and softwood they may be useful for same or different purposes.
