New microsatellite markers were used to characterize a set of 78 pomegranate accessions from Turkey. Using six SSR primers, a total of 41 alleles were characterized with an average of 4.6 alleles per locus and mean probability of identity (PI) value of 0.366. These data indicated a high level of polymorphism in pomegranate germplasm. Five synonymous groups could be detected among 30 accessions. This microsatellite-based key is a first step towards a database for marker- assisted identification of pomegranate accessions in Turkey. The present study provides essential information to devise a pomegranate core germplasm collection without duplication of plant material, to sustainably manage pomegranate breeding programs, and to establish conservation strategies for preserving local pomegranate genetic resources.

  • Pomegranate Peel Extract Activities As Antioxidant and Antibiofilm Against Bacteria Isolated from Caries and Supragingival Plaque
    Volume 13, Number 3, September 2020 ISSN 1995-6673 JJBS Pages 403 - 412 Jordan Journal of Biological Sciences Pomegranate Peel Extract Activities as Antioxidant and Antibiofilm against Bacteria Isolated from Caries and Supragingival Plaque Sabria Benslimane, Ouafa Rebai*, Rachid Djibaoui, and Abed Arabi Laboratory of Microbiology and Vegetal Biology, Faculty of Natural Sciences and Life, University of Mostaganem, Algeria Received: October 5, 2019; Revised: November 20, 2019; Accepted: November 22, 2019 Abstract The present study aimed to extract polyphenols from pomegranate (Punica granatum L.) peel extract (PPE) by maceration using three different solvants: acetone 70%, ethanol 70% and methanol 70% (v/v). The antioxidant capacity potential was determined by scavenging activity of free radicals (DPPH) and ferric reducing power (FRAP) assays. The antimicrobial activity of PPE was evaluated against six oral pathogens isolated from dental caries and supragingival plaque (Streptococcus mutans, Enterococcus faecalis, Gemella morbillorum, Staphylococcus epidermis, Enterococcus bugandensis and Klebsiella oxytoca). The highest total phenolic and flavonoid contents were obtained with ethanolic PPE (204.67 ± 15.26 26 mg gallic acid equivalents (GAE)/g dry weight (DW), 67.67 ± 1.53 mg quercetin equivalent (QE)/g DW respectively). The highest proanthocyanidin content was observed with acetonic extract (220 ± 17.32 mg catechin equivalent (CE)/g DW). The phenolic profile of ethanolic PPE was determined by HPLC analysis; peduncalagin, punigluconin and punicalagin as a predominant ellagitannin have been identified. The highest scavenging activity (87.37 ± 1.36%) was exhibited by ethanolic PPE with the lowest IC50 value (220 ± 14µg/ml) for DPPH, whereas the highest reducing power assay was observed with acetonic PPE with a value of 1.48 at 700 nm.

Functional Foods in Health and Disease 2016; 6(12):769-787 ABSTRACT Background: Numerous in vitro and in vivo studies, in addition to clinical data, demonstrate that pomegranate juice can prevent or slow-down the progression of some types of cancers. Despite the well-documented effect of pomegranate ingredients on neoplastic changes, the molecular mechanism(s) underlying this phenomenon remains elusive. Methods: For the study of pomegranate ingredients the electron-ion interaction potential (EIIP) and the average quasi valence number (AQVN) were used. These molecular descriptors can be used to describe the long-range intermolecular interactions in biological systems and can identify substances with strong electron-acceptor properties.

Box 4195, Murcia 30080, Spain, and Department of Horticultural Science, Private Bag X1, Matieland 7602, South Africa The antioxidant activity of pomegranate juices was evaluated by four different methods (ABTS, DPPH, DMPD, and FRAP) and compared to those of red wine and a green tea infusion. Commercial pomegranate juices showed an antioxidant activity (18-20 TEAC) three times higher than those of red wine and green tea (6-8 TEAC). The activity was higher in commercial juices extracted from whole pomegranates than in experimental juices obtained from the arils only (12-14 TEAC). HPLC- DAD and HPLC-MS analyses of the juices revealed that commercial juices contained the pomegranate tannin punicalagin (1500-1900 mg/L) while only traces of this compound were detected in the experimental juice obtained from arils in the laboratory. This shows that pomegranate industrial processing extracts some of the hydrolyzable tannins present in the fruit rind. This could account for the higher antioxidant activity of commercial juices compared to the experimental ones. In addition, anthocyanins, ellagic acid derivatives, and hydrolyzable tannins were detected and quantified in the pomegranate juices.

India Received on: 01-01-2011; Revised on: 04-02-2011; Accepted on:21-03-2011 ABSTRACT Plants contain diverse groups of phytochemicals such as tannins, terpenoids, alkaloids, and flavonoids that possess enormous antimicrobial potential against bacteria, fungi and other microorganisms. These are much safer than synthetic drugsand show lesser side effects. Approximately 25 to 50 % of current pharmaceuticals are derived from plants. Plant products are also used for the treatment of skin urinary, cardiovascular and respiratory diseases, which also show antidiarrheal, hepato-protective, hypoglycemic, lipid lowering, antiseptic, and antioxidant activities. Few important plant products such as ellagic acid coumarin, gallic acid, benzenoide, chebulic acid, corilagin, punicalagin, terchebulin, terflabin A-tannin, ellagic acid, ethyl acetate, galloyl glucose and chebulagic acid, triterpenes, flavonoids, quercetin, pentacyclic triterpenoids, guajanoic acid, saponins, carotenoids, lectins, leucocyanidin, ellagic acid, amritoside, beta- sitosterol, uvaol, oleanolic acid and ursolic acid are considered as prominent antimicrobial agents. Natural products also exhibit high susceptibility to drug resistant microbial pathogens such as methicillin- resistant and methicillin- sensitive strains of Staphylococcus aureus. These effectively check proliferation of MRSA. Some of these natural products are used as alternative medicine which are much safer and show lesser side effects than the synthetic drugs. Plant products have ethnopharmacological importance and are used as traditional medicine and food by local tribes.
