Background: Numerous plant extracts have demonstrated antioxidant properties as well as antimicrobial effects. The hydroalcoholic (8:2) and petroleum ether extracts derived from the peels of Trapa natans and Punica granatum, obtained through the microwave-assisted extraction (MAE) method, have exhibited notable antioxidant and antimicrobial activities.
Aim: The primary aim of this study was to comparatively evaluate the in vitro antioxidant and antimicrobial activities of Trapa natans (water chestnut) and Punica granatum (pomegranate), two medicinal plants commonly used in traditional medicine for their therapeutic properties
Method: The Hydro alcoholic (8:2) and Petroleum Ether extracts of both plants were subjected to TPC, TFC, DPPH Assay, and FRAP Assay, while antimicrobial activity was assessed against selected Gram-positive and Gram-negative bacterial strains using the agar well diffusion method
Results: Results showed that both plants had significant antioxidant activity, with Punica granatum showing marginally superior radical scavenging efficiency in its hydro alcoholic extract when prepared via the Microwave Assisted Extraction (MAE) technique. Punica granatum also displayed a broader spectrum of antimicrobial activity and larger zones of inhibition
Conclusion: These findings indicate the potential of both plant extracts as natural antioxidants and antimicrobial agents, and thus reinforcing their promising applications in the development of pharmaceutical and nutraceutical products.
