Abstract

This study aims to determine the effects of the extracts of Streblus asper, Cymbopogon citratus, Syzygium aromaticum and its formulation of green synthesized silver nanoparticle (AgNPs) on Streptococcus mutans growth and biofilm formation. The ethanolic extracts of S. asper, C. citratus, S. aromaticum, and a mix of the three herbs demonstrated antibacterial activity against S. mutans isolates by reducing bacterial biofilm formation and decreasing bacterial cell surface hydrophobicity. The formulated AgNPs from the ethanolic extracts could enhance the antibacterial activities of the plant extracts. Molecular docking found the best interaction between luteolin isolated from C. citratus and glucosyltransferase protein (GtfB), assuming the promising anti-biofilm activity. The scanning electron microscopy revealed morphological changes in the biofilm structure and a significant decrease in the biofilm area of the AgNPs treated. The study suggested that the extracts and its application could be used as natural alternative agents with multi-action against S. mutans infections.

草药提取物及其绿色合成纳米颗粒制剂对变形链球菌相关生物膜的抗菌作用

本研究旨在确定Streblus asper、Cymbopogon citratus、Syzygium芳香草的提取物及其绿色合成银纳米粒子（AgNPs）配方对变形链球菌生长和生物膜形成的影响。S.asper、C.citratus、S.aromicum的乙醇提取物和三种草药的混合物通过减少细菌生物膜的形成和降低细菌细胞表面的疏水性，对变形链球菌分离株表现出抗菌活性。由乙醇提取物配制的AgNPs可以增强植物提取物的抗菌活性。分子对接发现，从柠檬曲霉中分离的木犀草素与葡萄糖基转移酶蛋白（GtfB）之间的相互作用最好，假设其具有良好的抗生物膜活性。扫描电子显微镜显示，经处理的AgNPs的生物膜结构发生了形态学变化，生物膜面积显著减少。研究表明，该提取物及其应用可作为天然替代剂，对变形链球菌感染具有多种作用。
