Glycyrrhiza glabra assisted green synthesis of metallic nanoparticles with different applications: A review

Abstract

Several attempts have been made for green synthesis of nanoparticles of different metals, revealing the significance of plant extract in reducing metal source to nanoparticles and applications in various scientific domains. This article focus on the applications on licorice root extract in synthesis of nanoparticles of various metals like gold, zinc, silver etc. Glycyrrhiza glabra is a general herb of the Asian region belonging to family fabaceae and it is commonly used in the diet. Roots of this plant show range of activities including antioxidant, antimutagenic level. And respective research attempts, this metallic nanoparticles were evaluated for one or more applications like anticancer, antibacterial, antioxidant activity etc. Use of Glycyrrhiza glabra polar extract indicated involvement of its polar phyto-compounds in reducing the metal source as stabilizing the nanoparticles. In conclusion it could be noted that metal nanoparticles have better antimicrobial, antioxidant, anticancer and nematicidal potential over the aqueous root extract.
