| Abstract: | In order to construct the rattan property database and improve the level of high value addition processing and utilization of rattan, the paper measures, determines and analyzes the main chemical components of Plectocomia himalayana. The results show that the average contents of holocellulose, acid-insoluble lignin, α-cellulose, hemicellulose, benzene-alcohol soluble extractives, hot water soluble extractives, cold water soluble extractives, 1%NaOH soluble extractives and ash content are 67.98%, 16.72%, 43.91%, 24.38%, 9.78%, 18.85%, 15.02%, 38.60% and 1.46%, respectively. In the diameter direction, the content of holocellulose, α-cellulose, acid-insoluble lignin and ash in different parts is ranked by cortex > middle layer > core, while the contents of hemicellulose and different extractives are just reversed. in radial direction. In the axial direction, the maximum contents of holocellulose, α-cellulose, acid-insoluble lignin and ash are in the middle of cane, while the maximum contents of hemicellulose and extractives are in the tip of cane. While the minimum contents of acid-insoluble lignin and α-cellulose are in the tip of cane, the minimum contents of holocellulose, hemicellulose and ash are in the base of cane, the minimum contents of benzene-alcohol soluble extractives, cold water soluble extractives and 1%NaOH soluble extractives are in 2 m above the base of cane, and the minimum content of hot water extractives is in the middle of cane. |
