This study provides a detailed characterization of the invasive algae Rugulopteryx okamurae, highlighting its nutritional composition, mineral content, and potential bioactive compounds. This biomass contains 14.18 % protein, 21.29 % lipids (with a high omega-3 content), fibre (31.32 %), and significant amounts of minerals like calcium, sodium, potassium, sulphur, and iron. Phenolic compounds (0.74 %) and volatile compounds, such as retinol, were also identified. Peptidome analysis revealed 626 unique peptides, with 21 low molecular weight peptides showing potential activity against angiotensin converting enzyme and dipeptidyl peptidase IV when assessed using in silico tools and using molecular docking. Additionally, the antioxidant capacity of the alga was demonstrated with a significant free radical inhibition (EC: 2.09 mg/mL). Overall, this study provides initial evidence on the nutritional potential of R. okamurae, which may have potential for future applications in food and biotechnology fields.
本研究对入侵藻类冈村凹顶藻进行了详细表征，重点介绍了其营养成分、矿物质含量和潜在的生物活性化合物。这种生物质含有14.18%的蛋白质、21.29%的脂质（富含omega-3）、纤维（31.32%）以及大量的矿物质，如钙、钠、钾、硫和铁。还鉴定出了酚类化合物（0.74%）和挥发性化合物，如视黄醇。肽组分析揭示了626种独特的肽，其中21种低分子量肽在使用计算机工具和分子对接进行评估时，显示出对血管紧张素转换酶和二肽基肽酶IV的潜在活性。此外，该藻类具有显著的自由基抑制能力（EC：2.09mg/mL），证明了其抗氧化能力。总体而言，本研究为冈村凹顶藻的营养潜力提供了初步证据，其在食品和生物技术领域可能具有未来应用潜力。
