The study aimed to extract and characterize natural fibers from (Vent.) Boiss. plants and assess the impact of alkali treatment on the physicochemical and antioxidant properties of these fibers. Fibers were extracted from dried aerial parts by grinding with an average yield of 18.1%. Physicochemical and FTIR analysis revealed that the hemicellulose was mostly lost during alkali treatment. Results of the X-ray diffraction and thermogravimetric analysis indicated that the crystallinity and thermal stability of fibers were considerably increased after alkali treatment. In antioxidant activity assessment studies, raw fibers of showed significantly higher radical scavenging and reducing power potentials compared to the alkali-treated samples, indicating that the majority of antioxidant components such as lignin and other polyphenols were lost from fibers during alkali treatment. In conclusion, the promising antioxidant activity of raw can be utilized in developing functional materials, particularly for cosmetic and wound healing applications.
该研究旨在从（Vent.）Boiss.植物中提取并表征天然纤维，并评估碱处理对这些纤维的物理化学和抗氧化性能的影响。通过研磨从干燥的地上部分提取纤维，平均产率为18.1%。物理化学和傅里叶变换红外光谱（FTIR）分析表明，半纤维素在碱处理过程中大部分损失。X射线衍射和热重分析结果表明，碱处理后该植物纤维的结晶度和热稳定性显著提高。在抗氧化活性评估研究中，与碱处理样品相比，该植物的原生纤维表现出显著更高的自由基清除能力和还原电位，这表明在碱处理过程中，该植物纤维中的大部分抗氧化成分如木质素和其他多酚类物质流失。总之，该植物原生纤维有前景的抗氧化活性可用于开发功能材料，特别是用于化妆品和伤口愈合应用。
