is widely used in Ethiopia for treating various human ailments, yet its pharmacological properties and chemical composition remain largely unexplored. The chromatographic separation of roots extract afforded five compounds, namely tremulacin (), cochinchiside A (), 5-methoxydurmillone (), catechin-7--α-L-rhamnopyranoside (), and stigmasterol (), confirmed via IR, NMR, and MS spectral data. This is the first report of these compounds from this plant, except for compounds and . The extracts and isolated compounds were tested for antibacterial activity against , , , , , and strains. Methanol roots extract exhibited significant antibacterial activity (MIC 0.195 mg/mL) against and . Compounds and showed remarkable antibacterial activity, with compound (MIC 0.625 mg/mL) exhibiting antibacterial activity against and , whereas compound (MIC 0.625 mg/mL) exhibited antibacterial activity against and . Molecular docking analysis revealed better binding energies for compound (-8.0, -9.7, and -8.0 kJ/mol) and compound (-9.0, -8.7, and -8.4 kJ/mol), compared to ciprofloxacin (-8.3, -7.5, and -6.7 kJ/mol), in regard to pyruvate kinase, FtsZ, and Topoisomerase IV, respectively. ADME analysis also revealed good antibacterial candidacy of these compounds, provided that in vivo analysis is conducted for further confirmation of the results.
在埃塞俄比亚,它被广泛用于治疗各种人类疾病,但其药理特性和化学成分在很大程度上仍未得到探索。根部提取物的色谱分离得到了五种化合物,即震颤素()、柯钦奇甙A()、5-甲氧基杜米隆()、儿茶素-7--α-L-鼠李吡喃糖苷()和豆甾醇(),通过红外光谱、核磁共振光谱和质谱数据得以确认。除了化合物和外,这是首次从该植物中报道这些化合物。对提取物和分离出的化合物进行了针对、、、、和菌株的抗菌活性测试。甲醇根部提取物对和表现出显著的抗菌活性(最低抑菌浓度为0.195毫克/毫升)。化合物和表现出显著的抗菌活性,化合物(最低抑菌浓度为0.625毫克/毫升)对和表现出抗菌活性,而化合物(最低抑菌浓度为0.625毫克/毫升)对和表现出抗菌活性。分子对接分析表明,与环丙沙星(分别为-8.3、-7.5和-6.7千焦/摩尔)相比,化合物(分别为-8.0、-9.7和-8.0千焦/摩尔)和化合物(分别为-9.0、-8.7和-8.4千焦/摩尔)在丙酮酸激酶、FtsZ和拓扑异构酶IV方面具有更好的结合能。药物代谢动力学分析还表明,这些化合物具有良好的抗菌潜力,前提是进行体内分析以进一步证实结果。
