Abstract

BACKGROUND

(mugwort) is a member of the daisy family Asteraceae and is widely propagated in Saudi Arabia. has historical medical importance in traditional societies. The current study aimed to assess the antibacterial and antifungal characteristics of the aqueous and ethanolic extracts of . In addition, the study investigated the effect of silver nanoparticles (AgNPs) synthesized from the extract.

METHODS

The ethanolic and aqueous extracts and AgNPs were prepared from the shoots of . The characteristics of AgNPs were assessed by UV-visible spectroscopy, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS). The antibacterial experiments were performed against , , , and . The fungal species used were , , , , and . The antibacterial and antifungal characteristics were evaluated by measuring the diameter of growing organisms in Petri dishes treated with different concentrations of either extracts or AgNPs compared to the untreated controls. Furthermore, TEM imaging was used to investigate any ultrastructure changes in the microbes treated with crude extracts and AgNO.

RESULTS

The ethanolic and aqueous extracts significantly decreased the growth of , , and ( < 0.001), while was not affected. Unlike crude extracts, AgNPs had more substantial antibacterial effects against all species. In addition, the mycelial growth of was reduced by the treatment of both extracts. mycelial growth was decreased by the aqueous extract, while the growth of was affected by the ethanolic extract and AgNPs ( < 0.001). None of the treatments affected the growth of or . TEM analysis showed cellular ultrastructure changes in the treated and compared to the control.

CONCLUSION

The biosynthesized AgNPs and extracts of have a potential antimicrobial characteristic against pathogenic bacterial and fungal strains and nullified resistance behavior.

摘要

背景

艾蒿是菊科植物的一种，在沙特阿拉伯广泛分布。在传统社会中具有重要的历史医学价值。本研究旨在评估艾蒿水提取物和乙醇提取物的抗菌和抗真菌特性。此外，该研究还考察了由艾蒿提取物合成的银纳米颗粒（AgNPs）的作用。

方法

从艾蒿的嫩枝中制备乙醇提取物、水提取物和AgNPs。通过紫外可见光谱、透射电子显微镜（TEM）、傅里叶变换红外光谱（FTIR）和动态光散射（DLS）对AgNPs的特性进行评估。针对金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌和铜绿假单胞菌进行抗菌实验。所使用的真菌种类为白色念珠菌、黑曲霉、烟曲霉、黄曲霉和热带念珠菌。通过测量与未处理对照相比，用不同浓度的提取物或AgNPs处理的培养皿中生长微生物的直径，来评估抗菌和抗真菌特性。此外，利用TEM成像研究用粗提取物和硝酸银处理的微生物的任何超微结构变化。

结果

乙醇提取物和水提取物显著降低了金黄色葡萄球菌、大肠杆菌和枯草芽孢杆菌的生长（P < 0.001），而铜绿假单胞菌未受影响。与粗提取物不同，AgNPs对所有菌种具有更强的抗菌作用。此外，两种提取物的处理均降低了白色念珠菌的菌丝生长。水提取物降低了黑曲霉菌丝的生长，而乙醇提取物和AgNPs影响了黄曲霉菌丝的生长（P < 0.001）。没有一种处理影响热带念珠菌或烟曲霉的生长。TEM分析显示，与对照相比，处理后的金黄色葡萄球菌和白色念珠菌细胞超微结构发生了变化。

结论

生物合成的AgNPs和艾蒿提取物对致病细菌和真菌菌株具有潜在的抗菌特性，并消除了耐药行为。
