ABSTRACT

Spices are an important part of the human diet. They have been used for thousands of years to enhance the flavor, color, and aroma of food. In addition to boosting flavor, spices are also known for their preservative and medicinal value which forms one of the oldest sciences.The present study planned to synthesize silver nanoparticles from methanolic extract of the spice star anise (Illicium verum). The presence of silver nanoparticles are observed from the UV- Vis spectroscopy and the chemical components from FTIR analysis. The nanoparticles synthesized from the methanolic extract of star anise are tested for antimicrobial activity against different bacterial and fungal strains. Antimicrobial activity of seed extract might be related to their phenolic compounds synthesised by them and also by the presence of different secondary metabolite like hydroxyl groups on the active constituents. Thus, the spice is considered to be of much therapeutic value is eco-friendly, cost effective and has great effect of microbicidal.
