【 摘 要 】

The changes of the primary chemical compositions in 2- and 4-year-old Bambusa vulgaris andSchizostachyum brachycladum were investigated. The bamboo culms of known age 2- and 4-year-oldharvested from the forest reserve area in Jeli, Kelantan. The bamboo culms segregated into three portionsnamely the bottom, middle and top. They were then processed and analysed in their primary chemicalcompositions such as extractive, holocellulose, α-cellulose, hemicellulose, and lignin content. Standardoutlined by the Technical Association of the Pulp and Paper Industry (TAPPI) followed. The bottom portion of4-year-old B. vulgaris species possesses higher extractive content to compare the other portions, ages, andspecies. B. vulgaris also possessed a higher percentage of holocellulose yield with over than 90% on 2-year agecompared to the S. brachycladum species. S. brachycladum possessed a higher percentage in α-cellulose andlignin content in the two-year-old culms while hemicellulose showed slightly higher of yield in the 4-year-old.B. vulgaris and exhibited an increment in lignin and α-cellulose from 4 to 6% from 2 to 4-year-olds culms, whileS. brachycladum showed an increase of 1-15% in the holocellulose, α-cellulose and lignin. The high chemicalcontent was related to the high density that gives influence to their hardness, strength, wall thickness andcomplex cell wall structure.
