The aim of this study was to investigate the potential of retrieving polyphenolic antioxidants directly from wet pomegranate marcs: the fresh by-products obtained after pomegranate juice processing. These by-products mainly consist of internal membranes (endocarp) and aril residues. Even if they are still edible, they are usually discharged during juice production and, thus, they represent a great challenge in an eco-sustainable industrial context. Green technologies, such as ultrasound assisted extraction (UAE) and microwave assisted extraction (MAE), have been employed to convert these organic residues into recycled products with high added value...

Fatty acid composition of pomegranate (Punica granatum L.) seed oil (PSO) is dominated by punicic acid, a conjugated linolenic acid (18:3, ω-5). As a free fatty acid, punicic acid is rapidly oxidized in air and extensively isomerizes upon acid-catalyzed methylation at 90 °C. In contrast, triacylglycerol-bound punicic acid in PSO was unchanged by simulated gastric conditions and was degraded for 5-7% by severe heating (up to 170 °C for 4 h), as herein assessed by gas chromatography, attenuated total reflectance-Fourier transform infrared spectroscopy, 1H and 13C NMR and high-resolution electrospray ionization mass spectrometry...

Molecular mechanisms involved in arsenic-induced toxicity are complex and elusive. Liver is one of the most favored organs for arsenic toxicity as methylation of arsenic occurs mostly in the liver. In this study, we have selected a range of environmentally relevant doses of arsenic to examine the basis of arsenic toxicity and the role of pomegranate fruit extract (PFE) in combating it. Male Swiss albino mice exposed to different doses of arsenic presented marked hepatic injury as evident from histological and electron microscopic studies...

High blood pressure, or "hypertension," is associated with high levels of oxidative stress in the paraventricular nucleus of the hypothalamus. While pomegranate extract is a known antioxidant that is thought to have antihypertensive effects, the mechanism whereby pomegranate extract lowers blood pressure and the tissue that mediates its antihypertensive effects are currently unknown. We have used a spontaneously hypertensive rat model to investigate the antihypertensive properties of pomegranate extract. We found that chronic treatment of hypertensive rats with pomegranate extract significantly reduced blood pressure and cardiac hypertrophy...

Multiple myeloma (MM) is a clonal B-cell malignancy characterized by an accumulation of clonal plasma cells (PC) in the bone marrow (BM) leading to bone destruction and BM failure. Despite recent advances in pharmacological therapy, MM remains a largely incurable pathology. Therefore, novel effective and less toxic agents are urgently necessary. In the last few years, pomegranate has been studied for its potential therapeutic properties including treatment and prevention of cancer. Pomegranate juice (PGJ) contains a number of potential active compounds including organic acids, vitamins, sugars, and phenolic components that are all responsible of the pro-apoptotic effects observed in tumor cell line...

Cigarette smoke (CS) accounts for the outcome of several pathologies, even including lung cancer, cardiovascular disease and chronic obstructive pulmonary disease (COPD). Under healthy conditions, lung immune system becomes tolerant in response to various external stimuli. CS exposure alters the pulmonary immune equilibrium, thus leading to a condition of hyper activation of the local innate and adaptive immunity. COPD is one of the major complications of chronic CS exposure where a pro-inflammatory profile of the pulmonary and systemic immunity is predominant...
