A simple biological method for the synthesis of gold nanoparticles (AuNPs) using Cassia auriculata aqueous leaf extract has been carried out in the present study. The reduction of auric chloride led to the formation of AuNPs within 10 min at room temperature (28°C), suggesting a higher reaction rate than chemical methods involved in the synthesis. The size, shape and elemental analysis were carried out using X-ray diffraction, TEM, SEM-EDAX, FT-IR and visible absorption spectroscopy. Stable, triangular and spherical crystalline AuNPs with well-defined dimensions of average size of 15-25 nm were synthesized using C. auriculata. Effect of pH was also studied to check the stability of AuNPs. The main aim of the investigation is to synthesize AuNPs using antidiabetic potent medicinal plant. The stabilizing and reducing molecules of nanoparticles may promote anti-hyperglycemic if tested further.
本研究采用 Cassia auriculata 水提液进行了一种简单的生物方法来合成金纳米粒子（AuNPs）。金的氯化物的还原导致 AuNPs 在室温（28°C）下在 10 分钟内形成，这表明反应速率高于化学方法。使用 X 射线衍射、TEM、SEM-EDAX、FT-IR 和可见吸收光谱进行了尺寸、形状和元素分析。使用 C. auriculata 合成了稳定的、三角形和球形的结晶 AuNPs，具有平均尺寸为 15-25nm 的良好定义尺寸。还研究了 pH 值的影响以检查 AuNPs 的稳定性。研究的主要目的是使用具有抗糖尿病作用的药用植物合成 AuNPs。如果进一步测试，纳米粒子的稳定和还原分子可能会促进抗高血糖。
