Antioxidant properties and antimicrobial activity of manuka honey versus Polish honeys

Abstract

Originating from New Zealand manuka honey distinguishes itself from other honeys. The purpose of this study was to compare the antioxidant and antimicrobial properties of manuka honey and selected Polish honeys. Antioxidant capacity, total polyphenol and total flavonoid content were determined. Furthermore, the antimicrobial activity and the Minimum Inhibitory Concentration (MIC) were evaluated. Obtained results demonstrated that manuka honeys possessed relatively high antioxidant capacity compared to the other, Polish honeys. It was only honeydew honey that achieved comparable antioxidant properties to manuka honeys. The findings were supported by the results of microbial assays. Manuka MGO-250 and MGO-400, alongside honeydew honey, showed a stronger antimicrobial effect against Gram(?) than against Gram(-) bacteria. Moreover, the MIC-values, expressed as an inhibin number, proved the high antibiotic activity of manuka honey against the strains of Staphylococcus aureus and Enterococcus faecalis. Research concerning the influence of manuka honey on human health should be continued.

Melissopalynology and antioxidant properties used to differentiate Schefflera abyssinica and polyfloral honey

“…The current studies for Schefflera abyssinica and polyfloral honey were in line with the report of Escuredo et al [ 36 ] for Spain polyfloral honey (35.7 ± 13.0%) and Goslinski et al [ 37 ] for New Zealand Manuka honey (40.0 ± 0.3%). Honey samples originated from Italy were characterized by higher variability of the % DPPH scavenging activity (64.03 ± 7.75%) [ 38 ].…”

Quality Evaluation of Light- and Dark-Colored Hungarian Honeys, Focusing on Botanical Origin, Antioxidant Capacity and Mineral Content

“…One of the most studied parameters of the honey is the antioxidant capacity, due to its richness in antioxidant compounds, which are synthetized by plants partly as secondary metabolites against reactive oxygen species [ 2 , 4 ]. Even in the last few years, several researchers have measured the total antioxidant parameters along with other properties of honey types from different countries, such as the characterization of Turkish honeys by Gül et al [ 5 ], Polish honeys by Dzugan et al [ 6 ], Goslinski et al [ 7 ] and Halagarda et al [ 8 ], Greek honeys by Stagos et al [ 9 ], Serbian honeys by Sreckovic et al [ 10 ], Romanian honeys by Pauliuc et al [ 11 ] or Hungarian honeys by Bodó et al [ 12 ]. The researchers used various methods for determining total antioxidant capacities (TAC), such as the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay for antiradical activity based on electron transfer and the oxygen radical absorbance capacity (ORAC) method based on hydrogen atom transfer [ 13 ].…”

Studies of efficacy of Achillea species ethanol extract and honey on full thickness wound healing in diabetic albino rats

“…An increase in PCNA immune-expression was reported in many models of herbal medication of cutaneous wounds and burns like curcumin 44 and Nigella sativa 45 . The enhancement of cellular proliferation was attributed to antioxidants activity of those herbs, that could be also the underlying cause of what was observed with honey and Achillea extract 28,31 .…”

“…Both honey and Achillea were previously reported to possess wound healing promotion effects based on their effective antioxidant properties. Honey was tried with effective results in promoting healing of oral ulcer in experimental animal models 30 and clinical trials 2 .The effects of most types of honeys used were mostly related to their antimicrobial and antioxidant properties 31 . As was documented by Dons and Soosairaj 32 who reported that honey enhanced wound healing by stimulated tissue growth, enhanced epithelial growth and reduced scar formation, and this was because honey is acidic, containing hydrogen peroxide, nutrients and antioxidants, and enhanced immunity.…”
