摘要:
为研究黑木相思树皮的化学成分，评价树皮潜在的商业价值，从而推进黑木相思人工林的多功能经营，根据国家标准对黑木相思树皮的pH值、抽出物含量、纤维素、半纤维素、木质素等化学成分进行测定，并通过气相色谱质谱联用仪分析了其苯醇抽提物的化学组成。结果表明：黑木相思树皮的pH值为5.41，冷水抽出物、热水抽出物、1%NaOH抽出物含量分别为23.81%，31.24%，68.51%；综纤维素、α-纤维素、半纤维素、酸不溶木质素和酸溶木质素含量分别为59.31%，27.60%，31.71%，18.29%和4.10%；灰分含量为1.69%，苯醇抽提物含量为3.92%；通过GC-MS共鉴定出17种化合物，主要化合物为1,3-二乙氧基-1,1,3,3-四甲基二硅氧烷（23.38%）、八甲基环四硅氧烷（19.44%）、二甲基二乙氧基硅烷（12.94%）、硫酸二乙酯（10.08%）和十甲基环五硅氧烷（8.01%）。黑木相思树皮可作为燃料、造纸原料使用，还可用于制作乙醇，其抽出物可用于胶黏剂、化妆品、医药等领域，具有广泛的应用前景。
Abstract:
To understand the chemical composition of Acacia melanoxylon bark, evaluate its potential commercial value, promote acacia plantations multi-functional business, according to the national standard, pH value, extract content, chemical components such as cellulose, hemicellulose, and lignin were determined, and by gas chromatography - mass spectrometry (GC-MS) the chemical composition of benzyl alcohol extract was analysed.The results indicated that the pH value of A. melanoxylon bark was 5.41. The extraction yields were as follows: cold water extract (23.81%), hot water extract (31.24%), and 1% NaOH extract (68.51%). The bark contained holo cellulose (59.31%), alpha-cellulose (27.60%), hemicellulose (31.71%), acid-insoluble lignin (18.29%), and acid-soluble lignin (4.10%). The ash content was 1.69%, and the benzyl alcohol extract content was 3.92%. GC-MS identified 17 compounds in the bark, with main compounds was 1,3-diethoxy-1,1,3,3-tetramethyldisiloxane（23.38%）, Octamethylcyclotetrasiloxane（19.44%）, Diethoxydimethylsilane（12.94%）, Diethyl sulfate（10.08%） and Decamethylcyclopentasiloxane（8.01%）. A. melanoxylon bark has potential applications as a fuel, raw material for papermaking, and in ethanol production. Additionally, the extracts can be utilized in adhesives, cosmetics, pharmaceuticals, and other industries, demonstrating broad application prospects.
