Recent EU directives have encouraged member states to follow circular economy guidelines on waste reuse, especially for waste originating from wood agro‐forest biomass. Delineating the antioxidant and chemical activity of biomass is a starting point to find new ways to utilize such materials. Here, an 8‐year‐old apricot (Prunus armeniaca L.) tree stand located in southern Italy was evaluated. First, dendrometric parameters (total volume, diameter, and height of trunk below the branches) and physical‐mechanical properties (density, total, tangential and radial shrinkage, moisture content, and compression strength) of timber collected from five experimental plots was evaluated. Bark and wood from apricot pruning were then subjected to different extraction techniques, in vitro antioxidant assays, and gas chromatographic studies to determine their antioxidant activity and their phytochemical composition. Bark had the highest antioxidant activity compared to wood. Several antioxidant compounds (e.g., scopoletin and naringenin) were detected in the samples, explaining the measured antioxidant activity. In conclusion, this study demonstrates the potential of using apricot extracts in nutraceutical, cosmeceutical, and industrial fields. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

果园生物量残渣:杏树的化学成分,生物学活性和木材特性

欧盟最近的指令鼓励成员国遵循关于废物再利用的循环经济准则,特别是对于源自木材农林生物质的废物。描绘生物质的抗氧化剂和化学活性是寻找利用这种材料的新方法的起点。在这里,对位于意大利南部的8岁杏(Prunus armeniaca L.)树木进行了评估。首先,评估了从五个试验区收集的木材的树木密度参数(总体积,直径和树干以下的树干高度)和物理机械性能(密度,总含量,切向和径向收缩率,水分含量和抗压强度)。然后对杏修剪的树皮和木材进行体外不同的提取技术抗氧化剂测定和气相色谱研究,以确定其抗氧化剂活性及其植物化学组成。与木材相比,树皮具有最高的抗氧化活性。在样品中检测到了几种抗氧化剂化合物(例如大麦草碱和柚皮素),解释了所测得的抗氧化剂活性。总之,这项研究证明了在保健食品,药妆和工业领域中使用杏提取物的潜力。©2021化学工业协会和John Wiley&Sons,Ltd
