Table 1_Harnessing marine plant extracts for sustainable agriculture, livestock management, industrial use, and biomedical applications.docx

Marine plants are emerging as versatile resources for bioactive compounds with antioxidant, antibacterial, anti-inflammatory, and anticancer properties. Beyond their therapeutic potential, marine extracts offer agronomic and industrial value as biostimulants, natural pigments, biodegradable packaging materials, and green corrosion inhibitors, and serve as reducing agents in the synthesis of biomedical nanoparticles. This review integrates evidence from 256 studies (2011–2025), revealing rapid growth in the field over the past two years. The findings highlight the capacity of marine extracts to enhance crop and livestock productivity, yield stable natural dyes, create smart polysaccharide-based films, and protect metals via phenolic and sulfated polysaccharide fractions. Nanoparticles synthesized from these extracts exhibit improved biological performance. By linking agricultural, industrial, and biomedical perspectives, this work underscores the multifaceted potential of marine plant extracts and outlines future priorities in molecular characterization, strain development, and scalable green processing.

海洋植物正逐渐成为兼具抗氧化、抗菌、抗炎及抗癌活性的生物活性化合物的多功能优质资源。除治疗应用潜力外，海洋提取物还可作为生物刺激剂、天然色素、可生物降解包装材料与绿色缓蚀剂，兼具农业与工业应用价值，同时可在生物医学纳米颗粒的合成过程中充当还原剂。本综述整合了2011年至2025年间的256项研究成果，揭示了该领域在近两年来的快速发展态势。研究结果显示，海洋提取物可通过酚类及硫酸化多糖组分，实现作物与畜禽生产力提升、稳定天然染料制备、智能多糖基薄膜开发及金属防护等目标。由此类提取物合成的纳米颗粒展现出更优良的生物学性能。本研究通过整合农业、工业与生物医学多维度视角，阐明了海洋植物提取物的多领域应用潜力，并明确了分子表征、菌株选育及规模化绿色加工等未来研究的重点方向。
