Orange orchards are typical Mediterranean crops and a major feature of the heritage of the Mediterranean basin, where they play an important environmental and economic role. Their high availability, low price, and potential industrial application make the development of new and valuable uses of the orange's biomass of high interest. This research was focused: (i) on recognition and mapping of orange cultivation in the Basilicata region; (ii) on the evaluation of the antioxidant capacity of extracts; (iii) on identification of extractives' traits. To achieve these objectives, the anti‐oxidative properties and chemical compounds of the extracts from orange orchard biomass were analyzed. Different extraction techniques were applied, including maceration, ultrasound‐assisted extraction, accelerated solvent extraction, and autoclaving. Results demonstrated the potential antioxidant activity of the bark and wood of orange‐tree biomass, which has not been investigated before. The relative antioxidant capacity index showed that bark extracts were more effective than wood ones, and accelerated solvent extraction was the most effective process for recovering antioxidants. Chemical characterization by liquid chromatography–mass spectrometry (LC–MS) showed the presence of different natural compounds, including caffeic acid, alkaloids, and flavonoids. The development of innovative applications that use biomass derivatives could lead to their possible use in the market as a commodity for the chemical or cosmetic industries, giving new added value to the current use of biomass from agricultural practices. Through multi‐criteria analysis it was possible to recognize the sustainability of these cropping models and their ecological function, using them for the preservation of environmental resources, environmental quality, and quality of life. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

通过不同提取技术获得的桔树（Citrus sinensis L.）生物质提取物的化学分析和抗氧化性能

橙色果园是地中海地区的典型农作物，是地中海盆地遗产的主要特征，在其中发挥着重要的环境和经济作用。它们的高可用性，低价格以及潜在的工业应用使得人们对橙子生物质的新的有价值的用途的开发产生了浓厚的兴趣。这项研究的重点是：（i）在巴斯利卡塔地区的橙色栽培的识别和制图；（ii）评估提取物的抗氧化能力；（iii）鉴定提取物的特征。为了实现这些目标，分析了橘园生物质提取物的抗氧化特性和化学成分。应用了各种提取技术，包括浸渍，超声辅助提取，加速溶剂提取和高压灭菌。结果表明橙树生物质的树皮和木材具有潜在的抗氧化活性，以前尚未进行过研究。相对抗氧化能力指数表明，树皮提取物比木材提取物更有效，加速溶剂提取是回收抗氧化剂的最有效方法。液相色谱-质谱（LC-MS）进行化学表征显示，存在不同的天然化合物，包括咖啡酸，生物碱和类黄酮。使用生物质衍生物的创新应用的开发可能会导致其可能在市场上用作化学或化妆品工业的商品，从而为农业实践中目前使用的生物质提供新的附加价值。通过多标准分析，有可能认识到这些种植模式及其生态功能的可持续性，并将其用于保护环境资源，环境质量和生活质量。©2020年化学工业协会和John Wiley＆Sons，Ltd
