Antimicrobial activities of pomegranate rind extracts: enhancement by addition of metal salts and vitamin C

Abstract

Background: Punica granatum L. or pomegranates, have been reported to have antimicrobial activity against a range of Gram positive and negative bacteria. Pomegranate formulations containing ferrous salts have enhanced although short-term, antibacteriophage activities which are rapidly diminished owing to instability of the ferrous combination. The aim of this study was to determine the antimicrobial activities of combinations of pomegranate rind extracts (PRE) with a range of metals salts with the added stabiliser vitamin C.

Antibacterial activity of aqueous extract of pomegranate peel against Pseudomonas stutzeri isolated from poultry meat

“…Similarly, Alzoreky (2009) reported that water methanol extract was thermo stable, since they retained activity after boiling or sterilization. McCarrell et al (2008) also demonstrated antibacterial activity of autoclaved pomegranate peel extract against Staphylococcus aureus and B.subtilis. The antibacterial effect of PPE was further tested by broth dilution assay.…”

Evaluation of Antibacterial Activity of Aqueous and Methanolic Extracts of Pomegranate Peels (Punica Granatum Lin.) Against Some Bacteria

“…McCarrell et al [25] reported that Staphylococcusaureus and Ps. aeroginosa have the highest sensitivities to the aqueous extract of pomegranate peel.…”

The Therapeutic Potential of Pomegranate and Its Products for Prevention of Cancer

“…Food-borne illnesses are still an important concern for both consumers, the food industry and food safety authorities, thus, the ongoing search for natural antimicrobials for prevention of food-borne illnesses is a vast exploring area for scientists. Antimicrobial activities of pomegranate have been studied by some researchers and the extent of inhibitory effect is always attributed to the pomegranate antioxidant activity that depends mainly on the phenolic and anthocyanin content of the fruit (Holetz et al, 2002;Braga et al, 2005;Mathabe et al, 2006;McCarrell et al, 2008;Al-Zoreky, 2009;Duman et al, 2009;Gould et al, 2009;Parashar et al, 2009;Panichayupakaranant et al, 2010, Orak et al, 2011. In a previous study, Opara et al (2009) reported that the best activity against Staphyloccocus aureus and Pseudomonas aeruginosa were found in fruit peel compound punicalagin, particularly from Oman, which was coincident with the highest levels of vitamin C detected in these samples.…”
