Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place" downloadurl="http://www.5iantlavalamp.com/"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City" downloadurl="http://www.5iamas-microsoft-com:office:smarttags"> Biosynthesis of gold nanoparticles has emerged as an important area in nanotechnology and biotechnology due to growing need to develop environmentally benign technologies. Generally, nanoparticles are prepared by a variety of chemical methods which are not environmentally friendly. In the present study, we report a rapid and convenient method to reductively prepare gold nanoparticles from auric chloride using aqueous extract of <i>Mirabilis jalapa</i> flowers. The flower extract acts as a reducing agent and encapsulating cage for the gold nanoparticles. The production of gold nanoparticles has been done by the controlled reduction of the Au<sup>3+</sup> ion to Au<sup>0</sup>.<sup> </sup>The formation of gold nanoparticles has been established by FT-IR and UV-Vis spectroscopy, as well as by TEM, XRD, EDAX and AFM. The study suggests that <i>M. jalapa</i> flowers can be a cheap source as a reductant for the production of gold nanoparticles. </smarttagtype></smarttagtype>
