Pomegranate seed oil (PSO), which is the major source of conjugated linolenic acids such as punicic acid (PuA), exhibits strong anti-inflammatory properties. Necrotizing enterocolitis (NEC) is a devastating disease associated with severe and excessive intestinal inflammation. The aim of this study was to evaluate the effects of orally administered PSO on the development of NEC, intestinal epithelial proliferation, and cytokine regulation in a rat model of NEC. Premature rats were divided into three groups: dam fed (DF), formula-fed rats (FF), or rats fed with formula supplemented with 1.5% of PSO (FF + PSO). All groups were exposed to asphyxia/cold stress to induce NEC. Intestinal injury, epithelial cell proliferation, cytokine production, and trefoil factor 3 (Tff3) production were evaluated in the terminal ileum. Oral administration of PSO (FF+PSO) decreased the incidence of NEC from 61 to 26%. Feeding formula with PSO improved enterocyte proliferation in the site of injury. Increased levels of proinflammatory IL-6, IL-8, IL-12, IL-23, and TNF-α in the ileum of FF rats were normalized in PSO-treated animals. Tff3 production in the FF rats was reduced compared with DF but not further affected by the PSO. In conclusion, administration of PSO protects against NEC in the neonatal rat model. This protective effect is associated with an improvement of intestinal epithelial homeostasis and a strong anti-inflammatory effect of PSO on the developing intestinal mucosa.

The aim of this investigation was to determine the content and composition of fatty acid in seed oil of red and purple pomegranate (Punica granatum L). The extraction process was performed by Soxhlet extractor with petroleum ether as solvent. The separation and identification of pomegranate seed oil was done by using GCMS. The total oil content of red and purple  pomegranate  were 128 g/kg d.w  and 103 g/kg d.w respectively. Both showed the same major fatty acids  as palmitic, stearic, oleic, linoleic and  punisic acid. Oleic acid (19-21%) and linoleic acid (20-21%) were found as the most  dominant fatty acids in red pomegranate, whereas purple pomegranate seed oil was dominated by oleic acid (41-43%) and punicic acid  (0-25%). Neutral lipid  fraction of  red and purple pomegranate seed oils was more dominant than glycolipid and phospholipid. Neutral  lipid fraction  of red and purple pomegranate seed oil were  89 % and 91% respectively.  Glycolipid fraction  of red and purple pomegranate seed oil were 8 % and 5 %, whereas phosholipid fraction of red and purple pomegranate seed oil were 3 % and 4 %. The punicic acid content of  total lipid of  purple pomegranate seed oil (PPSO) (0-25%) was higher than red pomegranate (RPSO) (9-16%). On the contrary neutral lipid of red pomegranate showed higher punicic acid content (54-75%) than the purple pomegranate (14-55%). Glycolipid of red pomegranate contained  punicic acid  (0-42%). The punicic acid content  of the phospholipid fraction of  red pomegranate was higher (0-22 %) than the one of purple pomegranate (0-2%).Key words : fatty acid, pomegranate, Punica granatum, punicic acid, seed oil

In vitroandin vivostudies have shown that punicic acid, a type of conjugated fatty acid and the main constituent of pomegranate seed oil (PSO), has anti-atherogenic effects. The present study aimed at determining the effect of PSO treatment on serum lipid profiles. This double-blind placebo-controlled randomised clinical trial included fifty-one hyperlipidaemic subjects, diagnosed according to National Cholesterol Education Program definition, and randomly assigned to the PSO and the control groups. The PSO and placebo groups received 400 mg PSO and placebo twice daily, respectively and were followed up for 4 weeks. Serum concentrations of lipids and lipoproteins were measured before and 4 weeks after intervention. Mean concentration of TAG and the TAG:HDL cholesterol (HDL-C) ratio were significantly decreased after 4 weeks in the PSO group as compared with baseline values (2·75 (sd1·40)v. 3·45 (sd1·56) mmol/l,P = 0·009 and 5·7 (sd4·6)v. 7·5 (sd5·0),P = 0·031, respectively). The treatment effect was statistically significant in the PSO group as compared with controls in diminution of cholesterol:HDL-C ratio (5·4 (sd1·5)v. 5·9 (sd1·4),P < 0·05) adjusted for baseline values. We found a mean difference for PSOv.placebo in HDL-C concentration (0·13 v. − 0·02 mmol/l) and cholesterol:HDL-C ratio ( − 0·42 v. 0·01,P < 0·05). Serum cholesterol, LDL cholesterol and glucose concentrations and body composition variables remained unchanged. It is concluded that administration of PSO for 4 weeks in hyperlipidaemic subjects had favourable effects on lipid profiles including TAG and TAG:HDL-C ratio.

Excessive use of refined flour, solid fats, and sugar in preparing baked products are considered to be unhealthy and is intricately linked with the development of lifestyle diseases. Replacing refined flour with whole wheat flour and solid fats with cold-pressed oil serves as an alternate option. The study was aimed at evaluating the physicochemical properties, nutrient composition, sensory attributes, and shelf life of cupcakes enriched using pomegranate seed oil (PSO). Vanilla and chocolate cupcake variants were prepared using 25 and 50% of PSO. A sensory panel consisting of 30 semi-trained participants was selected for evaluating the formulated products using a five-point hedonic scale. Nutrient content was estimated using standard techniques. The stability of the formulated product was determined by evaluating the physicochemical traits and microbial growth on the 0th, 4th, and 7th day. Mean scores of the sensorial analysis showed that the incorporation of PSO in cupcakes was highly accepted by the panel members. Chocolate cupcake containing 50% of PSO was found to be the most preferred product (3.53±0.94), followed by vanilla cupcake containing 25% of PSO (3.4±0.62). The moisture, protein, and fat content of chocolate cupcakes containing 25% of PSO were high. Cupcakes prepared with PSO can be stored for four days at room temperature. GC-MS analysis showed the presence of punicic acid, oleic acid, tocopherols, campesterol, sitosterols, stigmasterol, and α-tocopheryl acetate as pre-dominant fatty acid in unheated and heated PSO. In conclusion, cupcakes prepared using PSO showed acceptable physicochemical qualities and sensory properties which indicated its successful consumption by people affected with metabolic disorders.

AbstractNecrotizing enterocolitis (NEC) is a leading cause of mortality in preterm newborns. Intestinal barrier dysfunction is one key event in NEC pathogenesis. Human β-defensin-3 (hBD3), one member of cationic host defence peptides, was reported to reduce the development of necrotizing enterocolitis in a neonatal rat model. And autophagy was induced in the intestine of human and animals with NEC. We hypothesized that regulation of autophagy might play a critical role in hBD3-mediated protection against NEC injury. Autophagy activity was evaluated both in intestinal epithelial cells and in NEC models. Newborn Sprague-Dawley rats were divided randomly into four groups: Control + NS, Control + rapamycin, NEC + NS, and NEC + hBD3. Body weight, histological score, survival time, enterocyte migration and mucosal barrier were recorded. Our results showed that hBD3 pretreatment could effectively inhibit autophagy activity in cultured IEC-6 and Caco2 enterocytes, and CXCR4 might be involved in hBD3-mediated autophagy suppression. Moreover, hBD3-induced inhibition of autophagy significantly promoted the intestinal epithelial cell migration by wound healing assay and transwell migration assay. In the rat model of NEC, hBD3 could noticeably reduce the expression of autophagy-activated proteins, down-regulate the expression of inflammatory mediators, and promote the mucosal integrity. Our data suggest an additional role of hBD3-mediated protection against intestinal mucosal injury: inhibition of over-activated autophagy in enterocytes.
