Abstract

Abstract This study aims to investigate the sugar components which play an important role in the process of heartwood formation in young Swietania mahagoni. The methanol-water (70/30, v/v) extract was analyzed by GC-MS to determine sugar constituents. The content of methanol-water extract ranged from 3.7 to 7.8% based on dried wood. After a 4-5 year duration of heartwood formation in the sapwood, monosaccharide and alditol fractions doubly increased. This was followed by almost five times the content of cyclitols. In a radial variation, the content of major monosaccharides including fructose, glucose, mannose and xylose decreased from sapwood to heartwood, while arabinose, galactose, and sucrose in the age 5 years were only found in the sapwood. Meanwhile, the main content of cyclitols and alditols (arabitol) significantly decreased from sapwood to heartwood. The main monosaccharides and disaccharides represented by sucrose played a key role in the process of heartwood formation. Further studies are required to investigate the phenolic and lipophilic components as both are involved in heartwood formation. In addition, similar studies on alditol and cyclitol regarding their role in tropical wood are necessary.

甜枣幼树心材形成相关糖组分分析Jacq树

摘要本研究的目的是研究在幼年大花Swietania mahagoni心材形成过程中起重要作用的糖成分。通过GC-MS分析甲醇-水（70/30，v/v）提取物以测定糖成分。基于干燥木材，甲醇-水提取物的含量在3.7%-7.8%之间。4-5之后边材、单糖和醛糖醇组分心材形成的年持续时间增加了一倍。紧随其后的是环内酯含量的几乎五倍。从边材到心材，主要单糖（包括果糖、葡萄糖、甘露糖和木糖）的含量呈径向变化，而阿拉伯糖、半乳糖和蔗糖的含量在5岁时下降岁月只在边材中发现。同时，从边材到心材，环内酯和醛内酯（阿拉伯醇）的主要含量显著降低。以蔗糖为代表的主要单糖和双糖在心材的形成过程中起着关键作用。需要进一步的研究来研究酚类和亲脂性成分，因为它们都参与了心材的形成。此外，有必要对醛糖醇和环醇在热带木材中的作用进行类似的研究。

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.
