Punica Granatum L

Fruit samples of ‘Granada’, ‘Wonderful’ and ‘Hicaznar’ cultivars were collected in productive pomegranate orchard in Neretva valley, Metković (Croatia) and their pomological and chemical properties were compared. Significant differences among cultivars were noted between the studied traits. Fruit weight ranged from 429.37 g to 359.43 g and the lowest was recorded in cv. ‘Hicaznar’. Color of peel, aril and juice of all investigated cultivars was intensively red and dark red, respectively. ‘Granada’ and ‘Wonderful’ stood out with high juice yield compared with ‘Hicaznar’. Total soluble solid (TSS) of ‘Hicaznar’ (18.61%) was higher than that of ‘Wonderful’ (16.64%). Total acidity (TA) significantly differed among cultivars and ranged from 1.6% to 2.1%. According to the TSS/TA ratio investigated cultivars belong to the group of sour-sweet cultivars. Dissimilarity between cultivars was found in the phenolics content (TPC). It ranged from 679.6 to 906.6 mg/100 g D.W. where ‘Hicaznar’ stood out as a cultivar with highest TPC and also highest flavonoid and non-flavonoid content (521.1 mg/100 g D.W. and 385.5 mg/100 g D.W., respectively). In ‘Granada’ antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl was recorded for 64.1%, in ‘Wonderful’ 70.2% and the highest in ‘Hicaznar’ (74.5%). Results of this assessment are the basis for practical determination of the pomegranate use.

The study was conducted in 2017 in the district of Sivas. In the study, 20 genotypes, which are considered to be different from each other, taking into account the fruit characteristics such as color and size and shape, were determined from the hawthorns that were naturally grown in the flora of Suşheri. At harvest time, the fruit, which would be adequate for pomological and biochemical measurements and analyzes, was harvested. According to the results of the measurements and analyzes in the study, fruit weight was found to vary between 0.68 g and 6.35 g, fruit width was between 10.52 and 29.48 mm and fruit length was between 11.40 and 20.67 mm. The highest firmness values were recorded with the genotype (G) 20 genotype, while the G4 had the lowest values in terms of the firmness values of the fruit flesh. While there are no significant differences between the pH values of the genotypes, the differences between the genotypes in terms of SSC, TA and vitamin C contents are quite significant. It has been found that there are significant differences between the genotypes in terms of total phenolic, total flavonoid and antioxidant activity. The total phenolic content ranged from 218.8 (G17) to 605.8 (G5 and G8) mg GAE kg–1 f.w., while the lowest total flavonoid content was 21.58 (G 17) and the highest total flavonoid content was 67.75 (G9) mg GAE kg–1 f.w. When the antioxidant activity was evaluated, the DPPH values were 1.08 (G17) – 15.43 (14) mmol TE kg–1 f.w., the FRAP values were 15.43 (G16) – 47.23 (G8) mmol TE kg–1 f.w. respectively.

Abstract Pomegranate (Punica granatum L.) is a widely used fruit, which contains several interesting bioactive compounds and possess health-promoting properties. Seeing the importance of this fruit, it is crucial to study its quality characteristics. Hence, in the current study, we assessed phenolic content, flavonoid content and antioxidant activity of different plant parts (leaves, rind and arils) of two pomegranate cultivars (Kesar and Ganesh). The analysis of phytochemical constituents in the cultivars revealed that, the content of phenolics ranged from 49.3 to 602 mg TAE/g plant material and the content of flavonoids ranged from 0.27 to 18.8 mg RE/g plant material. The maximum amount of phenolics and flavonoids was observed in the rind extracts as compared to the leaves and arils in both the cultivars. On the other hand, the antioxidant activity determined by different antioxidant models exhibited various degrees of antioxidant activity in different plant parts of the cultivars and was found to be highest in rind and aril extracts than that of leaves. Among the solvents methanol and ethanol gave highest extraction yields as compared to water and acetone. Total phenolics and flavonoids were significantly different with methanol and ethanol being the most efficient solvent and acetone being the least efficient one. Correlation between the antioxidant activity and phenolics and flavonoid content was found to be significant. Thus the results strongly indicated that there were significant differences between pomegranate cultivars. Generally the cultivar Ganesh has higher antioxidant activity as well as total phenolics and flavonoid content in comparison to Kesar.

During the last decade consumption of pomegranate (Punica granatum L.) has been highly recommended, based on the presence of phytochemicals with health protective effects for humans. Apart from these compounds, pomegranate might apport high levels of minerals, however, they are likely to be affected by cultivar, environment and development stage of fruits. In this study, some physico-chemical characteristics along with minerals (P, K, Ca, Mg, Na, Fe, Mn, Zn and Cu) were determined in fruits in three development stage (immature, unripe and full ripe) of pomegranate cv. ‘Hicaznar’ grown in Antalya, Turkey. The most of physico-chemical characteristics and concentrations of minerals of pomegranate strongly influenced by development stage. Fruit weight was 7.25 g, 140.57 g and 423.16 g in immature, unripe and full ripe stages. 100 aril weight changed from 0.34 g to 33.21 g during development stage. Soluble solid content were 6.16%, 10.38% and 15.84% in immature, unripe and full ripe stages. The contribution to the intake of minerals was in general high, with special emphasis on the contributions of K, Ca and Mn.

Background: The natural antioxidants have an important role in the prevention of many diseases. The aim of study is to investigate phytochemical components, antioxidant activity and acute oral toxicity of Pomegranate (Punica granatum L.) fruit peel (PFP) extract. Materials and methods: Phytochemicals of PFP were determined by qualitative chemical tests, thin layer chromatography, total polyphenol and flavonoid contents. The PFP extract was evaluated for antioxidant activity by DPPH assay and MDA assay. In vivo acute oral toxicity test was conducted using Karber-Behrens method to determine LD50. Results: Results illustrated that PFP mainly contains flavonoids, alkaloids, tannins, triterpenes, saponins, and coumarins. PFP extract exhibited the total polyphenol and flavonoid contents with 189.97 mg gallic acid equivalent/g dry weight and 9.42 mg quercetin equivalent/g dry weight, respectively. The DPPH free radical scavenging and anti-lipid peroxidation activities of PFP extract were expressed with IC50 value of 4.80 μg/mL and 0.38 μg/ mL, sequentially. Simultaneously, the Dmax (the maximum dose administered to mice that no toxicity was observed) of PFP extract was determined to be 21.28 g/kg, equivalent to 35.64 g dried herb. Conclusion: The PFP extract is relatively safe and revealed high antioxidant activity.

Wild pomegranate (Punica granatum L.) fruit arils with high acid content are processed into dried arils (anardana) which is used as an ingredient in various medicinal formulations and culinary preparations. The various phenols and flavonoids are responsible for the antioxidant activity of anardana which signifies its functional benefits. The advanced packaging techniques like vacuum packaging, can retain higher antioxidant activity characteristics during storage. So, the present studies were carried out to compare the effect of packaging on total phenols, flavonoids, DPPH (2, 2-diphenyl-1-picrylhydrazyl) antioxidant activity, metal chelating activity, FRAP (ferric reducing antioxidant power) and reducing power of anardana prepared in mechanical cabinet drier. Anardana was packed in different packaging materials and stored under ambient and refrigerated temperature conditions. The overall effect of storage during 12 months revealed that there was a significant (p< 0.05) decrease in total phenols (180.95 to 161.76 mg GAE/100 g), flavonoids (40.60 to 32.66 mg QuE/100 g), DPPH antioxidant activity (61.23 to 56.13%), metal chelating activity (22.25 to 19.37%), FRAP (34.60 to 31.73 ?M Fe2+/100 g) and reducing power (0.610 to 0.521) which was observed less in anardana packed in ALPV (aluminium laminated pouches with vacuum) followed by ALP (aluminium laminated pouches) and gunny bags. Due to slower rates of degradation of various antioxidant compounds, the changes after 12 months of storage were lower under refrigerated conditions. The total phenols, flavonoids and DPPH antioxidant activity were reduced  from 180.95 to 167.24 and 156.28 mg GAE/100 g, 40.60 to 34.95 and 30.37 mg QuE/100 g and 61.23 to 57.99 and 54.27 % in refrigerated and ambient temperature conditions, respectively.

Pruning of fruit trees is an important aspect for the improvement of fruit quality and to minimize the pests and disease attack. Pruning was performed in the month of December in seven year old unpruned trees of Punica granatum cv. Knadhdri Kabuli having many interfering branching and a heavy infestation of bacterial blight orchard. The pruning treatments viz., T1: Retention of 15cm fruiting shoot length, T2: Retention of 30cm fruiting shoot length, T3: Retention of 45cm fruiting shoot length, T4: Retention of 60cm fruiting shoot length and T5: control (No heading back and no thinning) plant. The results of the present investigation revealed that among different pruning treatment, the best results in terms of shoot extension (56.34 cm), fruit size (Diameter 9.66 cm and Length 9.65 cm, fruit weight (278.50 g), marketable yield (10.25 kg) and fruit qualities were in fruits from T1 and T2 where retention of 15cm fruiting shoot length respectively and retention of 30cm fruiting shoot length were maintained. However, maximum fruit set (54.73%) was recorded in control, and it decreased with increasing pruning intensity. The pruning treatments also proved beneficial in controlling bacterial blight on fruit (12.86%) and leaf surface (26.60%) to some extent.
