Abstract:The search for suitable substitute for dwindling timber species has led to the study of technical properties of important non-timber forest products, especially bamboo. In Ghana, Bambusa vulgaris is the predominant bamboo species. There is limited knowledge about its chemical composition to enhance its use in paper making and also preservation treatment. The chemical and phytochemical properties of B. vulgaris from three major bamboo growing sites in Ghana were studied. Results revealed that the range of acetone extractives was between 1.00 and 2.4 per cent, whilst ethanol extractives range between 2.47 and 6.50 per cent. The klason lignin content ranged between 20.9 and 30.13 per cent. whilst the holocellulose values were between 69.01 and 72.34. Alpha cellulose ranged from 58.971 to 61.54 per cent. Analysis of results at P<0.05 revealed the components were not significant with site and height, except for the extractives (0,02-0.03). Post hoc test using Tukey Honestly Difference was significant for mean values between the bamboo sites: Akim Oda and Assin Fosu. Further, preliminary phytochemical screening also shows the absence of alkaloids, an important decay resistant indicator and the presence of anthraquinone
