Aim and Background: Coriander oleoresin is a natural food additive used to mask the unpleasant taste of various medicines in the pharmaceutical industry. Zinc oxide nanoparticles (ZnONPs) have a wide range of applications and can be prepared from various herbal extracts. In this study, coriander oleoresin mediated ZnONPs were prepared and evaluated for its antioxidant activity.
Materials and
Methods: Zinc oxide nanoparticles were synthesized using coriander oleoresin,
zinc sulphate and distilled water and kept in an orbital shaker to ensure
constant mixing. The formation of nanoparticles was confirmed both visually and
spectrophotometrically. The coriander oleoresin mediated ZnONPs were evaluated
for its antioxidant activity using DPPH assay and was compared with the
standard, ascorbic acid.
Results and
Discussion: The peak of nanoparticle formation was observed at 650 nm. The DPPH
assay revealed a dose-dependent antioxidant activity of Coriander oleoresin
mediated ZnONPs. The highest percentage inhibition obtained was 87.9% with 50
μL, the maximum concentration of nanoparticle used for the study compared with
the standard 92.2%.
