Medicinal plants, known for their antibacterial phytocompounds and secondary metabolites, offer promising potential in combating antibiotic-resistant bacteria. This study aimed to perform a phytochemical analysis of the methanol and dichloromethane extracts obtained from leaves using GC-MS. Furthermore, the antioxidant activity of the extracts was evaluated through the DPPH assay. And, their antibacterial activity was assessed against , , methicillin-resistant , and vancomycin-resistant enterococcus (VRE) bacterial strains. Based on the results 90-92% of these extracts consisted of phytocompounds with pharmaceutical properties. Of these, 5-methyl- 2-(1-methylethylidele), Cyclohexanone (Pulegone; CHO) comprised the highest percentage of the extracts, constituting 62% of methanolic extract and 81% of dichloromethane extract. Also, both methanolic and dichloromethane extracts showed potent antioxidant activity with IC of 277.6 µg/ml and 49.6 µg/ml, respectively. Moreover, these extracts demonstrated considerable antibacterial activity against the tested pathogens, especially against and VRE.
药用植物以其抗菌植物化合物和次生代谢产物而闻名,在对抗抗生素耐药细菌方面具有广阔的潜力。本研究旨在利用气相色谱-质谱联用仪(GC-MS)对从叶片中获得的甲醇提取物和二氯甲烷提取物进行植物化学分析。此外,通过DPPH法评估提取物的抗氧化活性。并且,评估它们对金黄色葡萄球菌、大肠杆菌、耐甲氧西林金黄色葡萄球菌和耐万古霉素肠球菌(VRE)菌株的抗菌活性。根据结果,这些提取物中有90-92%由具有药用特性的植物化合物组成。其中,5-甲基-2-(1-亚乙基)环己酮(胡薄荷酮;CHO)在提取物中所占比例最高,占甲醇提取物的62%和二氯甲烷提取物的81%。此外,甲醇提取物和二氯甲烷提取物均表现出较强的抗氧化活性,IC50分别为277.6μg/ml和49.6μg/ml。此外,这些提取物对测试的病原体表现出相当大的抗菌活性,尤其是对金黄色葡萄球菌和VRE。
