The present work was performed to evaluate the levels of phytochemical constituents and the antioxidant and antibacterial properties of marine red seaweed () and seagrass (). Quantitative phytochemical analysis, antioxidant activity and antimicrobial activity against five potential pathogenic bacteria was investigated. In each case, we found the presence of flavonoids, tannins, phenolic compounds, glycosides, steroids, carbohydrates and ashes. Alkaloids were only found in , though they were not found in . The antimicrobial properties of both and chloroform extracts were found to be antagonistically effective against the Gram-positive bacteria and the Gram-negative bacteria , and . GC-MS analysis revealed the presence of 94 bioactive compounds in and 104 bioactive compounds in , including phenol, decane, dodecane, hexadecane, vanillin, heptadecane, diphenylamine, benzophenone, octadecanoic acid, dotriaconate, benzene, phytol, butanoic acid and 2-hydroxyl-ethyl ether, which all played important roles in antioxidant and antibacterial activities. Thus, in view of the results, both and could be considered to be sources of ingredients with appreciable nutritional and medicinal value.
本研究旨在评估海洋红藻（）和海草（）的植物化学成分水平以及抗氧化和抗菌特性。对五种潜在病原菌进行了定量植物化学分析、抗氧化活性和抗菌活性研究。在每种情况下，我们都发现了黄酮类化合物、单宁、酚类化合物、糖苷、类固醇、碳水化合物和灰分的存在。生物碱仅在中发现，而在中未发现。发现和的氯仿提取物对革兰氏阳性菌和革兰氏阴性菌、和具有拮抗作用。气相色谱-质谱分析显示中存在94种生物活性化合物，中存在104种生物活性化合物，包括苯酚、癸烷、十二烷、十六烷、香草醛、十七烷、二苯胺、二苯甲酮、十八烷酸、三十三烷酸、苯、叶绿醇、丁酸和2-羟基乙基醚，它们在抗氧化和抗菌活性中都发挥着重要作用。因此，鉴于这些结果，和都可被视为具有可观营养和药用价值的成分来源。
