Due to their low cost, toxicity, and health risks, medicinal plants have come to be seen as useful products and sources of biologically active compounds. L., a medicinal plant with a long history, has a high bioactive metabolites content. Mangiferin (CHO) is primary isolated from 's leaves, which has many pharmacological benefits. In this investigation, ultrasonic-assisted extraction with ethanol as the extraction solvent was applied to obtain mangiferin from a local type of leaves. HPLC was performed after a dichloromethane-ethyl acetate liquid-liquid fractionation method. Further, UV-vis, FTIR, and NMR spectroscopy were utilized to elucidate the structure. Interestingly, purified mangiferin displayed promising antimicrobial efficacy against a diverse variety of fungal and bacterial pathogens with MICs of 1.95-62.5 and 1.95-31.25 µg/mL, respectively. Time-kill patterns also showed that mangiferin had both bactericidal and fungicidal action. Furthermore, it exhibited strong radical dosage-dependent scavenging activity (IC = 17.6 μg/mL) compared to vitamin C (Vc, IC = 11.9 μg/mL), suggesting it could be developed into a viable antioxidant agent. To our delight, the IC values of mangiferin for the MCF-7 and HeLa cell lines were 41.2 and 44.7 μg/mL, respectively, from MTT cell viability testing, and it was less harmful when tested against the noncancerous cell line. Notably, it significantly induced cell apoptosis in MCF-7 cells by 62.2-83.4% using annexin V-FITC/PI labeling. Hence, our findings suggest that mangiferin can be used in the medical industry to create therapeutic interventions and medication delivery systems for society.
由于其低成本、低毒性和健康风险,药用植物已被视为有用的产品和生物活性化合物的来源。L.是一种历史悠久的药用植物,具有高生物活性代谢物含量。芒果苷(C₁₉H₁₈O₁₁)主要从L.的叶子中分离出来,具有许多药理益处。在本研究中,采用以乙醇为提取溶剂的超声辅助提取法从当地一种L.的叶子中获得芒果苷。在采用二氯甲烷 - 乙酸乙酯液 - 液分馏法后进行高效液相色谱分析。此外,利用紫外可见光谱、傅里叶变换红外光谱和核磁共振光谱来阐明其结构。有趣的是,纯化的芒果苷对多种真菌和细菌病原体显示出有前景的抗菌功效,其最低抑菌浓度分别为1.95 - 62.5和1.95 - 31.25 μg/mL。时间 - 杀菌模式还表明芒果苷具有杀菌和杀真菌作用。此外,与维生素C(Vc,IC₅₀ = 11.9 μg/mL)相比,它表现出强烈的自由基剂量依赖性清除活性(IC₅₀ = 17.6 μg/mL),表明它可以被开发成一种可行的抗氧化剂。令我们高兴的是,通过MTT细胞活力测试,芒果苷对MCF - 7和HeLa细胞系的IC₅₀值分别为41.2和44.7 μg/mL,并且在针对非癌细胞系进行测试时危害较小。值得注意的是,使用膜联蛋白V - FITC/PI标记,它在MCF - 7细胞中显著诱导细胞凋亡达62.2 - 83.4%。因此,我们的研究结果表明芒果苷可用于医疗行业,为社会创建治疗干预措施和药物递送系统。
