中文摘要：

用植物的金属 nanoparticles 的生合成的快速的开发吸引了广泛的兴趣进一步调查这个新奇、 eco 友好的方法。在生合成过程，植物可以充当减少代理人，盖住代理人或形状指导代理人。然而，在植物识别各种各样的部件的特定的角色是挑战性的。在这研究，我们与栀子 jasminoides 埃利斯摘录使用银 nanoparticles 的生合成处理这个问题。银 nanoparticles 的形成过程被调查， nanoparticles 与紫外可见的光谱学被描绘， Fourier 变换红外线的系列和扫描电子显微镜学。结果显示栀子 jasminoides 埃利斯摘录能减少银离子形成银 nanoparticles，稳定 nanoparticles，并且影响形成银 nanowires 的银 nanocrystal 的生长。仅仅在摘录的 geniposide 为银 nanowires 展出好指导形状的能力。而卢丁，法国的酸和 chlorogenic 酸拥有减少并且盖住能力，牛的白朊是一个潜在的盖住代理人，这被发现而卢丁，法国的酸和 chlorogenic 酸拥有减少能力。

英文摘要：

Rapid development of biosynthesis of metal nanoparticles using plants has attracted extensive interests to further investigate this novel and eco-friendly method. In the biosynthesis process, the plant may act as reducing agent, capping agent or shape directing agent. However, identifying specific roles of various components in the plant is challenging. In this study, we use biosynthesis of silver nanoparticles with Gardenia jasminoides Ellis ex-tract to address this issue. The formation process of silver nanoparticles is investigated and the nanoparticles are characterized with the ultraviolet-visible spectroscopy, Fourier transform infrared spectra and scanning electron mi-croscopy. The results indicate that the Gardenia jasminoides Ellis extract can reduce silver ions to form silver nanoparticles, stabilize the nanoparticles, and affect the growth of silver nanocrystal to form silver nanowires. Only geniposide in the extract exhibits good shape-directing ability for silver nanowires. It is found that bovine albumin is a potential capping agent, whereas rutin, gallic acid and chlorogenic acid possess reducing and capping ability.
