Abstract

Abstract The result of this study is the chemical characterization of sapwood (SW) and heartwood (HW) of Fraxinus angustifolia native to Algeria. Lipophilic and hydrophilic extractives were isolated by means of an accelerated solvent extractor (ASE) using hexane and the acetone/water mixture respectively. The acid hydrolysis and methanolysis methods were used to determine cellulose and hemicelluloses contents. The Tappi Standards T 222 and UM 250 allowed Klason and acid-soluble lignin quantification respectively. Alkaline hydrolysis of wood samples followed by HPLC analysis was performed to determine the acetyl groups. The method detailed in TAPPI T 211 (2002) for determining the ash content was used. It was found that the SW and HW of Fraxinus A. had almost similar amounts of the main components, averaging 40.00 wt% cellulose, 28.00 wt% hemicelluloses within 18.00 wt% of xylan, 22.00 wt% lignin, 3% extractives and 0.83 wt% ash. However, the HW contained more triglycerides (0.08 wt%) than the SW (0.02 wt%). On the other hand, mannitol was the most predominant hydrophilic extractive in SW (1.60 wt%) than in HW (1.02 wt%). These findings are useful for practitioners in the paper, biofuel, cosmetics, food, pharmaceutical and chemical industries for the assessment of Fraxinus A. wood chemical treatment parameters.

阿尔及利亚狭叶Fraxinus angustifolia边材和心材的化学特性
摘要本研究对原产于阿尔及利亚的狭叶Fraxinus angustifolia边材(SW)和心材(HW)进行了化学表征。通过分别使用己烷和丙酮/水混合物的加速溶剂提取器(ASE)分离亲脂性和亲水性提取物。采用酸水解法和甲醇解法测定了纤维素和半纤维素的含量。Tappi标准T 222和UM 250分别允许Klason和酸溶性木质素定量。对木材样品进行碱性水解,然后进行HPLC分析以确定乙酰基。采用TAPPI T 211(2002)中详述的方法测定灰分。结果表明,Fraxinus A.的SW和HW的主要成分含量几乎相似,平均为40.00 纤维素重量百分比,28.00 18.00以内的半纤维素重量百分比 木聚糖的wt%,22.00 重量%木质素、3%提取物和0.83 灰分重量百分比。然而,HW含有更多的甘油三酯(0.08 wt%)比SW(0.02 wt%)。另一方面,甘露醇是SW中最主要的亲水性提取物(1.60 wt%)比HW(1.02 wt%)。这些发现对论文、生物燃料、化妆品、食品、制药和化工行业的从业者评估Fraxinus A.木材的化学处理参数是有用的。

期刊介绍: The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
