摘要:

目的: 筛选具有抗结核活性的民族药物,评估其活性并解析化学成分,为结核病治疗提供新思路。方法: 通过文献研究筛选15种民族药,制备总浸膏,采用固体琼脂纸片扩散法初筛抗耻垢分枝杆菌(Mycobacterium smegmatis, M.sm)活性;选择活性最佳药物提取有机相分离物(石油醚、二氯甲烷、正丁醇),通过刃天青微量肉汤稀释法检测对M.sm和卡介苗(Bacillus Calmette-Guérin,BCG)的最低抑菌浓度(minimum inhibitory concentration,MIC),并用微量肉汤稀释法检测对结核分枝杆菌标准株H37Rv及临床分离株(包括耐药菌株和敏感菌株)的活性;通过高效液相色谱-质谱(high-performance liquid chromatography-mass spectrometry,HPLC-MS)分析阴地蕨总浸膏及石油醚相分离物化学成分,初步分析其潜在抗结核活性机制。结果: 查询整理的15种民族药中,10种对M.sm有抑菌活性,阴地蕨活性最强[抑菌圈直径为(18.33±4.04)mm]。刃天青法药物敏感性试验检测阴地蕨总浸膏及其3个有机相分离物对M.sm和BCG的MIC显示,阴地蕨总浸膏和石油醚相分离物抑菌效果均明显,两者对M.sm的MIC均为1875μg/ml、对BCG的MIC分别为2μg/ml和1μg/ml;微量肉汤稀释法药物敏感性试验检测阴地蕨总浸膏和石油醚相分离物对11株结核分枝杆菌临床分离株MIC主要集中在14~58μg/ml,其中石油醚相分离物MIC最低达到14μg/ml。HPLC-MS分析阴地蕨总浸膏鉴别出44种化合物,石油醚相分离物鉴别出33种化合物。结论: 阴地蕨在15种民族药中抗M.sm活性最佳,进一步活性评价表明,阴地蕨特别是其石油醚相分离物具有显著抗结核活性。研究不仅验证了从民族药中筛选抗结核药物的可行性,其成分分析结果为开发新型抗结核药物提供了重要的候选物质与科学依据。

Abstract:

Objective: To screen ethnomedicines with anti-tuberculosis activity, evaluate their efficacy and chemical composition, and provide new insights for tuberculosis treatment. Methods: Fifteen ethnomedicines were selected through literature review, and their total extracts were prepared. Initial screening for activity against Mycobacterium smegmatis (M.sm) was performed using the solid agar disk diffusion method. The medicine with the best activity was further extracted to obtain organic solvent fractions (petroleum ether, dichloromethane, n-butanol). The minimum inhibitory concentrations (MIC) of these fractions against M.sm and Bacillus Calmette-Guérin (BCG) were determined by the resazurin microtiter broth dilution assay. The activity against the standard strain H37Rv and clinical isolates (including drug-resistant and drug-sensitive strains) of Mycobacterium tuberculosis was evaluated via the microbroth dilution method. The chemical constituents of the total extract and petroleum ether fraction from Botrychium ternatum were analyzed by high-performance liquid chromatography-mass spectrometry (HPLC-MS) to preliminarily explore the potential anti-tuberculosis components. Results: Among the 15 ethnomedicines screened, 10 exhibited inhibitory activity against M.sm, with Botrychium ternatum showing the strongest activity (inhibition zone diameter: 18.33±4.04 mm). Resazurin assay results indicated significant inhibitory effects for the total extract and the petroleum ether fraction of Botrychium ternatum against M.sm and BCG, with MICs of 1875 μg/ml against M.sm for both, and MIC of 2 μg/ml, and 1 μg/ml against BCG for total extract and the petroleum ether fraction, respectively. Microbroth dilution testing against 11 clinical isolates of Mycobacterium tuberculosis showed that the MICs for the total extract and the petroleum ether fraction mainly ranged from 14 to 58 μg/ml, with the lowest MIC for the petroleum ether fraction reaching 14 μg/ml. HPLC-MS analysis identified 44 compounds in the total extract and 33 compounds in the petroleum ether fraction of Botrychium ternatum. Conclusion: Botrychium ternatum demonstrated the best activity against M.sm among the 15 ethnomedicines. Further evaluation confirmed its significant anti-tuberculosis activity, particularly for its petroleum ether fraction. This study not only verified the feasibility of screening anti-tuberculosis agents from ethnomedicines, but also provided important candidate substances and scientific basis for developing new anti-tuberculosis drugs through compositional analysis.
