Abstract In the present investigation, antioxidant potential of the methanolic leaf extract was assessed using in vitro free radical scavenging and phosphomolybdenum assays. The (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) (ABTS•+) assay exhibited potent free radical scavenging capacity at 100 µg/mL (86.48 ± 0.8%). Antimicrobial activity of the methanolic leaf extract greatly inhibited the growth of Pseudomonas aeruginosa (9 ± 0.7 mm) and Echinodontium tinctorium (12 ± 0.9 mm) when compared to the other tested pathogens. The hemolysis (%) was calculated for anti-inflammatory activity and the results showed dose dependent effects. The lowest inhibition (53.08 ± 1.5%) was obtained for 800 μg/mL extract when compared with control aspirin (90.41 ± 1.3%) at the same concentration. Qualitative phytochemical tests confirmed the presence of triterpenoids, flavonoids, saponins, tannins, sterols, sugars and free aminoacids. Totally, 35 different phytochemical compounds were found using gas chromatography-mass spectrometry (GC-MS). Furthermore, the phenolics (70.34 ± 2.1 mg/g), flavonoids (164.28 ± 1.1 mg/g) and other metabolites were estimated quantitatively. These results demonstrated that the methanolic leaf extract of Plecospermum spinosum Trecul exhibited considerable antioxidant, and antimicrobial activities due to the presence of bioactive phytochemicals. P. spinosum may be employed for the separation of novel bioactive metabolites with potential pharmaceutical activities.

Plecospermum spinosum Trecul 的植物化学成分、抗氧化和抗菌活性

摘要 在本研究中,甲醇叶提取物的抗氧化潜力使用体外自由基清除和磷钼测定进行评估。(2,2'-叠氮基-双(3-乙基苯并噻唑啉-6-磺酸)) (ABTS•+) 检测在 100 µg/mL (86.48 ± 0.8%) 时表现出强大的自由基清除能力。与其他测试病原体相比,甲醇叶提取物的抗菌活性极大地抑制了铜绿假单胞菌 (9 ± 0.7 mm) 和 Echinodontium tinctorium (12 ± 0.9 mm) 的生长。计算抗炎活性的溶血 (%),结果显示剂量依赖性效应。与相同浓度的对照阿司匹林 (90.41 ± 1.3%) 相比,800 μg/mL 提取物的抑制作用最低 (53.08 ± 1.5%)。定性植物化学测试证实了三萜类化合物、黄酮类化合物、皂苷、单宁、甾醇、糖和游离氨基酸的存在。使用气相色谱-质谱法 (GC-MS) 总共发现了 35 种不同的植物化学化合物。此外,还对酚类物质 (70.34 ± 2.1 mg/g)、黄酮类化合物 (164.28 ± 1.1 mg/g) 和其他代谢物进行了定量评估。这些结果表明,由于存在生物活性植物化学物质,Plecospermum spinosum Trecul 的甲醇叶提取物表现出相当大的抗氧化和抗菌活性。P. spinosum 可用于分离具有潜在药物活性的新型生物活性代谢物。使用气相色谱-质谱法 (GC-MS) 发现了 35 种不同的植物化学化合物。此外,还对酚类物质 (70.34 ± 2.1 mg/g)、黄酮类化合物 (164.28 ± 1.1 mg/g) 和其他代谢物进行了定量评估。这些结果表明,由于存在生物活性植物化学物质,Plecospermum spinosum Trecul 的甲醇叶提取物表现出相当大的抗氧化和抗菌活性。P. spinosum 可用于分离具有潜在药物活性的新型生物活性代谢物。使用气相色谱-质谱法 (GC-MS) 发现了 35 种不同的植物化学化合物。此外,还对酚类物质 (70.34 ± 2.1 mg/g)、黄酮类化合物 (164.28 ± 1.1 mg/g) 和其他代谢物进行了定量评估。这些结果表明,由于存在生物活性植物化学物质,Plecospermum spinosum Trecul 的甲醇叶提取物表现出相当大的抗氧化和抗菌活性。P. spinosum 可用于分离具有潜在药物活性的新型生物活性代谢物。由于存在生物活性植物化学物质而具有抗菌活性。P. spinosum 可用于分离具有潜在药物活性的新型生物活性代谢物。由于存在生物活性植物化学物质而具有抗菌活性。P. spinosum 可用于分离具有潜在药物活性的新型生物活性代谢物。
