Abstract
Revisiting traditional uses and developing therapeutic applications of pomegranate (Punica granatum L.) non-edible parts have gradually attracted abroad attention for considerable healthy, economic, and environmental benefits. Infusion made from medicinal plants is one of the most commonly consumed beverages both in ancient and modern societies. The superiority of pomegranate leaf, as an agro-industrial waste has not yet reported thoroughly, although many researchers have outlined the importance of pomegranate fruit. The present work revealed that pomegranate leaf infusion (PLI) possessed high contents of total phenols, ortho-diphenols, flavonoids, and tannins, and displayed potent antioxidant capacities by diammonium cation radical and 2,2-diphenyl-1-picrylhidrazyl radical scavenging assays as well as ferric reducing antioxidant power method. PLI maintained good stability (> 90%) in the levels of total polyphenolics and in vitro antioxidant properties over one-day storage (0, 2, 4, 6, 8, 24 h), which may be related to the complex conversion and activity compensation among the identified individual compounds, especially ellagitannins. Moreover, PLI showed safe nature and exhibited anti-neoplastic and toxicological effects in the transgenic mice carrying human papillomavirus type 16 oncogenes, by reducing hydronephrosis lesions in kidneys and diminishing dysplasia and carcinoma lesions in the chest skin. Thus, PLI could be of great interest in the valorization of high added-value by-products and in the application of green and functional alternatives in the food-pharma and nutraceutical industries.
