چکیده
This research aimed to analyze the change in chemical composition of betung bamboo (Dendrocalamus asper) strands after alkali immersion treatment under various times. The culms were converted into with target length, width, and thickness 70, 25, 0.5 mm, respectively. Strands immersion-treated 1% NaOH solution for 1, 2, 3 h. Preparation powder component analysis refers Technical Association Pulp Paper Industry (TAPPI) standard T 264 cm-07 regarding preparation wood test samples analysis. Structural non-structural strand components such as holocellulose, alpha-cellulose, hemicellulose, klason lignin, extractives analyzed. results showed that decreased hemicellulose content from 21.55% before 20.30% h immersion. Thus, it changed holocellulose alpha-cellulose composition. Alkali also extractive substances dissolved cold water, hot NaOH, ethanol-benzene solution. decrease molecular weight would be beneficial bamboo-oriented board manufacture improve adhesion, dimensional stability, mechanical properties, durability against biological agents attack. Keywords: times, treatment, bamboo, components, pre-treatment

متن کاملThe Effects of 4-Hydroxybenzoic Acid Identified from Bamboo (Dendrocalamus asper) Shoots on Kv1.4 Channel.
Background Bamboo shoot has been used as a treatment for epilepsy in traditional Chinese medicine for generations to treat neuronal disorders such as convulsive, dizziness and headaches. 4-hydroxybenzoic acid (4-hba) is a non-flavonoid phenol found abundantly in Dendrocalamus asper shoots (bamboo), fruits (strawberries and apples) and flowers. Kv1.4 is a rapidly inactivating Shaker-related memb...
متن کاملChanges in Chemical Composition and Microstructure of Bamboo after Gamma Ray Irradiation
Changes in bamboo composition and microstructure following 60Co gamma (γ) ray irradiation were investigated by solid state 13C crosspolarization (CP) magic-angle spinning (MAS) spectroscopic nuclear magnetic resonance spectrometry (NMR) and a field emission scanning electron microscope (FESEM). The results indicated that irradiation doses lower than 100 KGy resulted in the degradation of hemice...
