Abstract

Background: Obesity is an immoderate or abnormal accretion of fat or adipose tissue in the body that is prone to damage the health of mankind. Persea americana (Avocados) is a nutritious fruit known for its several health benefits. The current research was planned to evaluate the anti-obesity activity of bioengineered Silver Nanoparticles (AgNPs) against a high-fat diet (HFD) treated obese albino rats.

Methods: AgNPs were synthesized and characterized for the Phytochemical constituents, UV-vis Spectroscopy, FTIR, SEM and XRD. Furthermore, the lipid profile in serum, biochemical parameters and histopathological changes in tissues of albino rats were determined.

Results: The present study revealed the presence of tannins, flavonoids, steroids and saponins, carbohydrates, alkaloids, phenols and glycosides. The peak was disclosed at 402 nm in UV-vis spectroscopy, confirming the synthesis of AgNPs. FTIR analysis showed two peaks at 3332.25 cm-1 which correspond to the O-H stretch of the carboxylic acid band, and 1636.40 cm-1 represents the N-H stretch of the amide of proteins, respectively. This result confirms their contribution to the capping and stabilization of AgNPs. The XRD results confirm the crystalline nature of AgNPs, and SEM results indicated that the synthesized AgNPs were spherical. Further, the results of the current study showed the improved lipid profile and biochemical parameters in rats supplemented with methanolic pulp extract of Persea americana AgNPs when compared with other experimental groups. The histopathological findings displayed improved results with reduced hepatocyte degradation under the influence of AgNPs treatment.

Conclusion: All the experimental evidence indicated the possible anti-obesity effect of silver nanoparticles synthesized from the methanolic pulp extract of Persea americana.
