【 摘 要 】

The purpose of this research is to determine the changes of chemical components content in andong bamboo (Gigantochloa pseudoarundinacea) and yellow bamboo (Bambusa Vulgaris var. striata) due to steam treatment and rinsing with water or sodium hydroxide solution. Samples was taken from culm without bark and node part of the bamboo. The treatments of sample were steam at 126 ?C and 0.14 MPa for 1 hour, steam and rinsing with water, and, steam and rinsing with 1% NaOH, respectively. Air-dried samples were, then, subjected to mill in order to get 40-60 mesh particle size, which was used for chemical components analyses. The results showed that steam and rinsing with water or 1% NaOH solution treatment reduced hemicellulose and extractive contents (dissolved in cold water, hot water, 1% NaOH solution, and ethanol-benzene), whereas alpha-cellulose and lignin were relatively stable. Steam and rinsing treatment generally increased the pH value of bamboo sample. The chemical component change of the bamboo due to the treatments would affect the quality of finish product manufactured especially on its physical and mechanical properties.
