In this paper, we have researched about production of nano gold particles by wheat. In this work influence of parameters such as temperature, pH value, time of reaction and concentration of chloride ions on production of nano gold particles has been studied.  The results showed that the highest adsorption (in spectrophotometer analysis) were at pH=2, time of reaction=5h, reaction temperature =45°C and concentration of chloride ions =5×10-3M. The results showed that reaction temperature has influence on figure and size of nano gold particles. Also in above optimum conditions, nano gold particles with range of size 5-50 nanometer have been produced.
