GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES FROM Illicium verum Hook. F AND THEIR ANTIOXIDANT AND ANTI DIABETICS ACTIVITY Authors: A Auxilia , HELEN DIANA I, ASHA MONICA A AND B. DHARSHINI
ABSTRACT
The study conducted qualitative phytochemical screening of Illicium verum Hook. F dried fruit extracts,
revealing varied concentrations of phytochemicals across solvents. Chloroform and ethanol extracts
exhibited high glycosides, steroids, and terpenoids, while aqueous and acetone extracts showed lower
phenols, flavonoids, and alkaloids. Green synthesis of silver nanoparticles from the fruit extract was
characterized by UV spectrum analysis, indicating silver ion reduction. FT-IR spectrum analysis identified
biomolecules responsible for ion reduction and revealed functional groups present. Scanning Electron
Microscope (SEM) images exhibited nanoporous structures with potential applications in drug delivery and
heavy metal adsorption. The antioxidant activity of dried fruit extracts, attributed to phenolic compounds,
was evaluated using the DPPH-assay method, demonstrating concentration-dependent free radical
scavenging effects surpassing standard ascorbic acid. The in vitro alpha amylase inhibitory assay indicated
promising antidiabetic activity of the extract compared to standard acarbose, suggesting further investigation
to isolate the active polyphenol. Overall, the study underscores the phytochemical richness and potential
health benefits of Illicium verum Hook. F extracts, advocating for additional research to elucidate their
therapeutic potential.
