Zinc oxide nanoparticles (ZnO-NPs) have been produced by physical and chemical methods. Here, the comparative evaluation of both chemically-synthesised ZnO-NPs (C-ZNPs) and in-vitro cultured S. marianum mediated green-synthesised ZnO-NPs (G-ZNPs) were investigated on seed germination frequency, root and shoot growth, callus induction and biochemical profile of medicinally important plant Silybum marianum. Of all the treatments, callus-mediated ZnO-NPs gave optimum results for seed germination (65%), plantlet's root length (4.3 cm), shoot length (5.3 cm) and fresh and dry weights (220.4 g L-1 and 21.23 g L-1, respectively). Similarly, the accumulation of phenolic (12.3 µg/mg DW) and flavonoid (2.8 µg/mg DW) contents were also enhanced in callus cultures treated with G-ZNPs. We also observed maximum antioxidant activity (99%) in callus cultures treated with G-ZNPs, however, in case of plantlets, these activities were found highest for in-vitro whole plant-mediated ZnO-NPs. Moreover, G-ZNPs also enhanced total protein content (265.32 BSAE/20g FW) in callus cultures. G-ZNPs were further assessed for their effects on several multidrug resistant bacterial strains and human liver carcinoma (HepG2) cells and our findings revealed that callus extracts treated with G-ZNPs show ameliorated antibacterial (highest zone of inhibition (19 mm) against Klebsiella pneumonia) and anticancer (highest cytotoxicity of 64%) activities.

绿色和化学合成的氧化锌纳米粒子:对水飞蓟体外幼苗和愈伤组织培养的影响及其抗菌和抗癌潜力的评价。

氧化锌纳米颗粒 (ZnO-NPs) 已通过物理和化学方法生产。在这里,化学合成的 ZnO-NPs (C-ZNPs) 和体外培养的 S. marianum 介导的绿色合成的 ZnO-NPs (G-ZNPs) 的比较评价在种子发芽频率、根和芽生长方面进行了研究,药用重要植物水飞蓟的愈伤组织诱导和生化特征。在所有处理中,愈伤组织介导的 ZnO-NPs 对种子萌发 (65%)、幼苗根长 (4.3 cm)、枝条长 (5.3 cm) 以及鲜重和干重 (220.4 g L-1 和 21.23 g L-1,分别)。同样,在用 G-ZNPs 处理的愈伤组织培养物中,酚类 (12.3 µg/mg DW) 和类黄酮 (2.8 µg/mg DW) 含量也增加了。我们还在用 G-ZNPs 处理的愈伤组织培养物中观察到最大的抗氧化活性 (99%),然而,在小植株的情况下,这些活性在体外全植物介导的 ZnO-NPs 中最高。此外,G-ZNPs 还提高了愈伤组织培养物中的总蛋白质含量(265.32 BSAE/20g FW)。进一步评估了 G-ZNPs 对几种多药耐药菌株和人肝癌 (HepG2) 细胞的影响,我们的研究结果表明,用 G-ZNPs 处理的愈伤组织提取物显示出改善的抗菌性(最高抑制区(19 毫米))对克雷伯菌肺炎) 和抗癌(最高细胞毒性为 64%)活性。32 BSAE/20g FW) 在愈伤组织培养物中。进一步评估了 G-ZNPs 对几种多药耐药菌株和人肝癌 (HepG2) 细胞的影响,我们的研究结果表明,用 G-ZNPs 处理的愈伤组织提取物显示出改善的抗菌性(最高抑制区(19 毫米))对克雷伯菌肺炎) 和抗癌(最高细胞毒性为 64%)活性。32 BSAE/20g FW) 在愈伤组织培养物中。进一步评估了 G-ZNPs 对几种多药耐药菌株和人肝癌 (HepG2) 细胞的影响,我们的研究结果表明,用 G-ZNPs 处理的愈伤组织提取物显示出改善的抗菌性(最高抑制区(19 毫米))对克雷伯菌肺炎) 和抗癌(最高细胞毒性为 64%)活性。
