Abstract

Abstract The European Deforestation Regulation 2023/1115 (EUDR) prohibits trading of wood and wood products obtained from illegal logging on the EU market. While the identification of solid wood via anatomy, chemistry and genetics has already been established, there is a lack of identification methods for pulp and paper that complement anatomy. This publication presents a newly developed chemotaxonomic method for identifying mixed tropical hardwood (MTH) species in pulp and paper products based on their extractives analyzed with thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The measured data was processed and compared to identify marker substances and was then merged into a fingerprint database for identifying MTH species in paper of unknown composition. As database references, fully bleached kraft pulps were produced from 38 anatomically identified wood samples and then cryo-ball milled and extracted successively with n -hexane and acetone. The results show that the remaining wood extractives generated from bleached pulps are specific enough to find chemical relevant marker substances to detect MTH species. As chemical composition and anatomy are independent characteristics of wood, this paper makes a completely independent method available, which potentially improves the screening for Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) protected species.

纸上热带树种的鉴定:一种基于提取物的化学分类新方法

欧洲森林砍伐条例2023/1115 (EUDR)禁止在欧盟市场上进行非法采伐木材和木制品的交易。虽然已经建立了通过解剖学、化学和遗传学鉴定实木的方法，但缺乏对纸浆和纸张的鉴定方法来补充解剖学。本文介绍了一种基于热解吸-气相色谱-质谱(TD-GC-MS)分析方法对纸浆和纸制品中混合热带硬木(MTH)树种进行化学分类的新方法。对测量数据进行处理和比对，识别标记物质，然后合并到指纹库中，用于鉴定未知成分纸张中的MTH物种。作为数据库参考，从38个解剖鉴定的木材样品中制备出完全漂白的硫酸盐纸浆，然后用正己烷和丙酮依次进行冷球研磨和提取。结果表明，漂白纸浆产生的剩余木材萃取物具有足够的特异性，可以找到与MTH物种相关的化学标记物质。由于木材的化学成分和解剖结构是木材的独立特征，本文提供了一种完全独立的方法，有可能提高《濒危野生动植物种国际贸易公约》(CITES)保护物种的筛选。

期刊介绍： Holzforschung is an international scholarly journal that publishes cutting-edge research on the biology, chemistry, physics and technology of wood and wood components. High quality papers about biotechnology and tree genetics are also welcome. Rated year after year as one of the top scientific journals in the category of Pulp and Paper (ISI Journal Citation Index), Holzforschung represents innovative, high quality basic and applied research. The German title reflects the journal''s origins in a long scientific tradition, but all articles are published in English to stimulate and promote cooperation between experts all over the world. Ahead-of-print publishing ensures fastest possible knowledge transfer.
