桉树树皮化学成分分析

摘要

[ Objective ] The chemical composition of eucalyptus plantation bark was determined and analyzed by using the Chinese wood chemical composition analysis national standards. [Method] Content of holocellulose, cellulose, lignin, ash, extractive of eucalyptus bark was determined ,and compared with other four kinds of plants. [ Result] The chemical compositions content of the eucalyptus plantation bark respectively were, bolocellulose 79. 35% , cellulose 46. 81 % , lignin 19. 69% , 1 % NaOH extraction content 19. 83% , cold water extraction content 5. 30% ,hot water extraction content 8.11% .benzene alcohol extraction content 2.63% ,ash content 2. 82%. [ Conclusion] Content of holocel-lulose, cellulose, ash, extractive were comparatively rich in eucalyptus bark, lignin was lower in eucalyptus bark.%[目的]采用我国木材化学成分分析国家标准,对人工林桉树树皮的化学成分进行了测定和分析.[方法]测定桉树树皮的综纤维素、纤维素、木质素、灰分、抽提物含量,并与其他4种植物进行比较.[结果]人工林桉树树皮化学成分含量分别为,综纤维素79.35％,纤维素46.81％,木质素19.69％,1％ NaOH抽提物19.83％,冷水抽提物5.30％,热水抽提物8.11％,苯醇抽提物2.63％,灰分2.82％.[结论]桉树树皮综纤维素、纤维素、灰分、抽提物含量较高,木质素含量较低.
