Products from nature or those derived from natural products, such as extracts of several plants or parts of plants, tea, coffee, banana, simple amino acids, as well as wine, table sugar and glucose, have been used as reductants and as capping agents during the present synthesis method. Polyphenols found in plant material often play a key role in the processes mentioned here. The techniques involved are generally one-pot processes, environmentally friendly and simple. Green synthesis of gold nanoparticles using several extracts and spices extracts was conducted, in which aqueous extracts HAuCl4.3H2O reduce to Au° has establishing themselves in specific crystal phase. Synthesized nanoparticles were confirmed by the color change of auric chloride which is yellow. The growth of nanoparticles was monitored by the behavior of surface Plasmon using UV-Vis spectroscopy; also the pH was determined meanwhile. Moreover, this approach is not only of a green rapid synthesis kind and considered as a better alternative to chemical synthesis, but also found to be effective for large scale synthesis of gold nanoparticles.
