Background and Objective:
In this study, dudoa (Hydnocarpus alcalae C.DC.) leaf extract
was used as a reducing and stabilizing agent in a novel one-step green synthesis of silver nanoparticles.
Dudoa is an endemic plant in the province of Legazpi, Philippines and its seed oil was used as an
anti-leprotic drug.
Method:
Therefore, the dudoa leaf extract was used to synthesize silver nanoparticles. Moreover, optimization
of various parameters greatly affected the size and morphology of the synthesized AgNPs
as indicated by the Ultraviolet-visible (UV-vis) spectrophotometry. The synthesized AgNPs were further
characterized using spectral analyses such as XRD, EDX, SEM, FT-IR, TGA and DLS. The antimicrobial
activity of synthesized AgNPs was also demonstrated.
Results and Discussions:
The synthesized AgNPs exhibited a diffraction pattern and a particle size
ranging from 22-48 nm. The AgNPs also showed complete inhibitory and mild reactivity against representative
pathogenic gram-positive (S.aureus) and gram-negative (E.coli) bacteria.
Conclusion:
Silver nanoparticles were successfully synthesized using H. alcalae leaf extract. Furthermore,
this green synthesis approach appeared to be cost-effective, non-toxic, and eco-friendly
which is a best alternative to the conventional chemical methods.
Green synthesis of silver nanoparticles using Lysiloma acapulcensis exhibit high-antimicrobial activity
