Antimicrobial activity of pomegranate (Punica granatum L.) fruit peels

Food-borne diseases like listeria meningitis and diseases caused by the emergence of multi-drug resistant pathogens (e.g. staphylococci aureus) are globally recognized as environmental hazards to the food provide and human health. Natural inhibitors for morbific microorganisms are explored in several plants. The antimicrobial activity against some food-borne pathogens by varied extracts from pomegranate fruit peels was evaluated victimisation each in vitro (agar diffusion) and in place (food) ways. The eightieth methanolic extract of peels (WME) was a potent substance for L. monocytogenes, S. [1]

Chemopreventive and adjuvant therapeutic potential of pomegranate (Punica granatum) for human breast cancer

Fresh organically mature pomegranates (Punica granatum L.) of the fantastic vascular plant were processed into 3 components: hard juice, binary compound seed vessel extract and cold-pressed or critical CO2-extracted seed oil. Exposure to extra solvents yielded polyphenol-rich fractions (‘polyphenols’) from every of the 3 parts. Their actions, and of the crude whole oil and crude hard and sweet juice concentrate, were assessed in vitro for doable chemopreventive or adjuvant therapeutic potential in human carcinoma. [2]

Studies on Antioxidant Activity of Pomegranate (Punica granatum) Peel Extract Using in Vivo Models

Pomegranate (Punica granatum) peel extracts are shown to possess vital inhibitor activity in varied in vitro models. Dried pomegranate peels were fine and extracted with alcohol for four h. The dried methanolic extract was fed to unusual person rats of the Wistar strain, followed by tetrachloride (CCl4), and also the levels of varied enzymes, like enzyme, peroxidase, and enzyme (SOD), and supermolecule peroxidation were studied. Treatment of rats with one dose of CCl4 at a pair of.0 g/kg of weight decreases the degree of enzyme, SOD, and oxidase by eighty one, 49, and eighty nine severally, whereas the supermolecule peroxidation price accrued nearly 3-fold. Pretreatment of the rats with a methanolic extract of pomegranate peel at fifty mg/kg (in terms of catechin equivalents) followed by CCl4 treatment causes preservation of enzyme, peroxidase, and SOD to values comparable management values, wheres supermolecule peroxidation was brought back by fifty four as compared to regulate.

Potential of Punica granatum biochar to adsorb Cu(II) in soil

Biochar as a promising adsorbent to get rid of serious metals has attracted a lot of attention globally. one amongst the potential adsorbents is biochar derived from pomegranate peels, a growing however typically wasted resource in tropical countries. However, the immobilization capability of pomegranate peel biochar isn’t renowned. This study investigated the chemistry properties of pomegranate peel boichars pyrolyzed at 300 °C and 600 °C (referred as BC300 and BC600), and therefore the potency and mechanisms of Cu(II) sorption of 5 styles of material treatments: BC300, BC600, soil only, and soils with biochar change BC300 and BC600, severally, at the speed of I Chronicles of the soil by weight.

Studies on Green Synthesis of Copper Nanoparticles Using Punica granatum

Aim: this study geared toward inexperienced synthesis of copper nanoparticles victimisation varied plant extracts as reducing and stabilising agents. it might conjointly study the medication result of the synthesized copper nanoparticles.

Place and period of Study: Department of biology, Bhavan’s Vivekananda school of Science, Humanities and Commerce, Hyderabad, India. The period of the study is for 6 months between could 2017 to Gregorian calendar month 2017.

Methodology: The liquid resolutions of various plant extracts were mixed with CuSO4 solution and incubated for inexperienced synthesis of stable copper nanoparticles. These were tested by UV-Visible spectrographic analysis and SEM analysis. medication tests of the biosynthesized nanoparticles were dole out on gram-positive bacterium cocci aureus by Agar well assay.
