Abstract

Background: Number of attempts has been made for green synthesis of nanoparticles of different metals and metal oxides, revealing the significance of natural extracts in reducing metal source to the corresponding nanoparticles and applications in various scientific domains. Objective: The present article focus on applications of extracts of different organs of Hygrophila schulli in fabrication of nanoparticles of various metals like silver and gold. H. schulli is annual, belonging to family Acanthaceae. The plant has been reported to contain several phytochemicals like triterpnoids flavonoids, and hydrocarbons. In respective research attempts, metallic nanoparticles so synthesized were evaluated for one or more applications like anti-microbial or anticancer activity and/or photocatalytic activity. Conclusions: Mostly, polar extracts of H. schulli are used for green synthesize of nanoparticles. This indicates involvement of polar phytocompounds of H. schulli in reducing the metal source and stabilizing the nanoparticles. In conclusion, it could be noted that metal nanoparticles have better antimicrobial activity and photocatalytic potential over extract.
