摘要

以十六烷、三氯甲烷和水为原料合成了银纳米粒子。AgNPs的合成通过叶提取物溶液的颜色变化来确认，然后通过紫外-可见光谱确认叶提取物中银离子的还原。在400～450nm范围内观察到表面等离子体共振（SPR）峰。通过动态光散射测量（DLS）、Zeta电位和透射电子显微镜（TEM）对合成的AgNPs进行了表征。XRD、傅立叶变换红外光谱（FTIR）、X射线衍射（XRD）分析证实了AgNPs的结晶性质和元素银的存在。银纳米粒子的尺寸在10-50nm之间，并且如DLS和TEM研究所发现的那样是球形的。通过DPPH测定，与粗叶提取物相比，合成的AgNPs显示出更高的抗氧化活性。在观察革兰氏阳性菌和革兰氏阴性菌的抑制区时，合成的AgNPs具有较高的抗菌活性。

Green synthesis of silver nanoparticles from fractionated Annona reticulata leaf extract in different solvents and analysis of its antioxidant and antibacterial activity

Silver nanoparticles were synthesized from fractionated leaf extract in Hexane, Chloroform and Water. Synthesis of AgNPs was confirmed by change in color of leaf extract solution, followed by confirming of reduction of silver ions in the leaf extract by UV-Visible spectroscopy. The Surface Plasmon resonance (SPR) peak was observed from 400 to 450nm. The biosynthesized AgNPs were characterized by dynamic light scattering measurement (DLS), Zeta potential and Transmission electron microscopy (TEM). The XRD, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis confirmed the crystalline nature of AgNPs and the presence of elemental silver. The size of the silver nano particles ranged from 10-50nm and were spherical in shape as found by DLS and TEM studies. The synthesized AgNPs showed higher antioxidant activity by DPPH assay as compared to the crude leaf extract. Antibacterial activity was higher in the synthesized AgNPs on observing the inhibition zone of Gram positive and Gram Negative bacteria.

期刊介绍： The Association of Biotechnology and Pharmacy (ABAP) will be useful to form a forum for scientists so that they can bring together to discuss and find scientific solutions to the problems of society. The annual meetings will help the members to share their knowledge and publish their research knowledge particularly by members and fellows of the Association and special care will be taken to provide an opportunity for young scientists. Besides this the association is planned to organize symposia, seminars and workshops on current developments of Biotechnology and Pharmacy particularly on the subject of current scientific interest, and the proceedings of which will be published regularly. And in view of the vast development of science and to disseminate the problems in publication of research work, an international journal of Current Trends in Biotechnology and Pharmacy has been started by ABAP.
