The medicinal plant, Coccinia cordifolia L. was analyzed for its chemical composition. The antimicrobial activities of the methanol, water, ethanol and ethyl acetate extracts of Coccinia cordifolia L. plant were evaluated against some Gram positive bacteria (Sarcina lutea, Bacillus subtilis and Staphylococcus aureus), Gram negative bacteria (Salmonella typhi, Shigella dysenteriae and Escherichia coli) and fungi (Candida albicans, Aspergillus niger and Penicillium notatum). Chemical analysis showed that the plant is rich in nutrients, especially antioxidant compounds such as total phenol, vitamin C and β-carotene. Phytochemical screening showed that the methanolic extract contains the bioactive constituents such as tannins, saponins, phenols, flavonoids and terpenoids. In the methanolic extract of the plant, promising antimicrobial potential was observed against the tested microorganism. Methanolic extract showed highest activity against Shigella dysenteriae, Escherichia coli, Staphylococcus aureus, and Candida albicans compared to the other extracts. Water extract showed less antimicrobial activity as compared to other extractants.
对药用植物心形南瓜(Coccinia cordifolia L.)进行了化学成分分析。评估了心形南瓜植物的甲醇提取物、水提取物、乙醇提取物和乙酸乙酯提取物对一些革兰氏阳性菌(藤黄八叠球菌、枯草芽孢杆菌和金黄色葡萄球菌)、革兰氏阴性菌(伤寒沙门氏菌、痢疾志贺氏菌和大肠杆菌)以及真菌(白色念珠菌、黑曲霉和青霉)的抗菌活性。化学分析表明,该植物富含营养成分,尤其是抗氧化化合物,如总酚、维生素C和β-胡萝卜素。植物化学筛选显示,甲醇提取物含有单宁、皂苷、酚类、黄酮类和萜类等生物活性成分。在该植物的甲醇提取物中,观察到对受试微生物有良好的抗菌潜力。与其他提取物相比,甲醇提取物对痢疾志贺氏菌、大肠杆菌、金黄色葡萄球菌和白色念珠菌表现出最高活性。与其他提取剂相比,水提取物的抗菌活性较低。
