摘要

对11年生银合欢茎皮的酸度、溶解度和化学性质进行了研究。将树皮从树干上剥下来，在自来水中温和清洗以去除污垢，然后在实验室室温(24 + 3°C)下风干2-3周。将树皮剁碎成粗粉，粉碎后通过BS 250μm筛网筛。风干几天后，对样品进行化学分析(灰分含量和pH值;在1%NaOH中的溶解度，热水和冷水的溶解度;萃取物，纤维素和木质素含量)。结果表明，白头马茎皮酸性最小(pH值为6.04)，灰分含量最高(15.76%)。树皮成分在1% NaOH中的溶解度(41.36%)高于热水(14.45%)和冷水(11.06%)。全纤维素和半纤维素含量分别为132.85%和103.66%。其中木质素含量最高(38.4%)，其次为纤维素(29.19%)和浸出物(8.39%)。本研究表明，白头翁树皮具有较低的酸性。树皮的高溶解度是潜在的碳水化合物资源，而树皮的化学成分可能会影响热解过程中的快速燃烧。

ACIDITY, SOLUBILITY AND CHEMICAL UTILIZATION OF LOCAL LEUCAENA LEUCOCEPHALA STEM BARK

Acidity, solubility and chemical properties of eleven years old of Leucaena leucocephala stem bark were investigated. The bark was peeled from the stem of tree and gentle washed in tap water to remove dirt before air-dried in the laboratory at room temperature (24 + 3°C) for 2-3 weeks. The bark was minced into coarse powder and grind to pass BS 250μm mesh sieve. After air-dried for several days, the samples were conducted to chemical analyses (ash content and pH value; solubility in 1%NaOH, hot and cold water solubility; extractive, cellulose and lignin content) based on ASTM standard methods. The results show that L. leucocephala stem bark considered as least acidic (pH value 6.04) and high ash content (15.76%). The solubility of bark components was higher in 1% NaOH (41.36%) compared to hot water (14.45%) and cold water (11.06%). Holocellulose and hemicellulose was 132.85% and 103.66%, respectively. Lignin was the major composition in L. leucocephala stem bark (38.4%) followed by cellulose (29.19%) and extractive (8.39%). This study indicated that the bark of L. leucocephala had less acidity. The high solubility of the bark potential as a carbohydrate resource, while the chemical component of the bark might influence rapid combustion during pyrolysis.
