Quality improvement of manuka honey through the application of high pressure processing
… processing can enhance antibacterial activity of Manuka honey significantly. It shows an increase in the percentage inhibition of Staphylococcus epidermidis from 64.15 ± 5.86% to 84.34 ± 7.62% when honey was subjected to 600 MPa. Storage studies for one year at room temperature (25°C) demonstrated …

Extraction of bioactive compounds from New Zealand Manuka leaves (Leptospermum scoparium) using emerging technologies
… area can expand uses of bioactive compounds. Manuka (Leptospermum scoparium) is one of the shrubs that used medicinally by Māori. The high level of bioactive compounds in Manuka leaves is responsible for the powerful antibacterial, antifungal, antioxidant/anti-ageing, and anti-inflammatory …

Argininderivatisierung und 1,2-Dicarbonylverbindungen in Lebensmitteln
… untersucht. Hier stellten die neuseeländischen Manuka-Honige (Manuka: Leptospermum scoparium, Teebaum) den Schwerpunkt der Untersuchung dar. Für die untersuchten Manuka-Honige konnten ungewöhnlich hohe Gehalte an Methylglyoxal bestimmt werden (von 347 bis 743 mg/ kg). Von 12 verschiedenen …

Assessment of Seedling Recruitment Under Manuka (Leptospermum scoparium) and Kanuka (Kunzea ericoides) Plantings at Shakespear and Wenderholm Regional Parks
Exclosure plots were monitored to investigate the impact of browsing on seedling recruitment by Trichosurus vulpecula, Oryctolagus cuniculus and Rattus rattus on seedlings under Leptospermum scoparium and Kunzea ericoides plantings in two Auckland Regional Council Parks (ARC), Shakespear and …

Investigating the Anti-inflammatory Activity of Honey
… treatments (LPS, PMA and Vit-D3) and Manuka honey. It was found that Manuka honey increased the expression of pro-inflammatory cytokines TNF-α and anti-inflammatory cytokines IL-10, IL-1ra and the growth factors PDGF and TGF-β. This indicated that Manuka honey may allow inflammation to …

A CONTRIBUTION TO THE STUDY OF BIOCONTROL AGENTS APITHERAPY AND OTHER POTENTIAL ALTERNATIVES TO ANTIBIOTICS
… antibacterial activity of Leptospermum scoparium Manuka honey was further investigated. It was shown that this activity is unlikely to be due to accumulated residual hydrogen peroxide and the microflora of bees and honey probably act as a source of any non–hydrogen peroxide inhibitory components. …

The effects of honey on the inflammatory response of cells with respect to wound healing
… was to test the effect of two types of honey, a manuka honey and an Otago pasture honey, on a range of key cell types involved in the inflammatory response of wound healing. A range of in vitro assays were used to test the effect of honey on various cells with a view to the implications of the …

Investigation of biofilm development by antibiotic resistant urinary tract infection pathogens and evaluation of antimicrobial activity of Manuka honey on Escherichia coli CTX-M-15 biofilms
… in this study. The antivirulence efficacy of Manuka honey as an alternative treatment was analysed for this strain. Method Biofilm formation was measured using the Tissue Culture plate method at different times: after 6, 12, 24 and 48 hours of incubation. Assuming that times correlated with …

Investigation of Biofilm Development by Antibiotic Resistant Urinary Tract Infection Pathogens and Evaluation of the Antimicrobial Activity of Natural Products on Carbapenem-Resistant Escherichia coli IMP and Klebsiella pneumoniae NDM-1.
… and to assess the anti-virulence effect of Manuka honey and garlic extract on the expression of eight virulence genes in each strain. To that end, structural changes during biofilm development and the impact of antimicrobial before and after treatment were assessed via confocal laser …

Indicators of bioactivity and floral origin of New Zealand honeys
… with close to 100% achieved for rata, kamahi, manuka, rewarewa and clover honeys. Honeys with a clover contribution: tawari, thyme, nodding thistle and vipers‟ bugloss displayed reduced performance in this model with a proportion of samples misclassified as clover honey. These results indicate …

Development of Bioassays Based on Nucleic Acid Amplification and Next-Generation Sequencing
… NGS, we have developed a method to authenticate Manuka honey, a high-value product native to New Zealand. We targeted the nuclear ribosomal ITS2 region of plant DNA of twenty-one different manuka samples. Using our in-house developed bioinformatics pipeline, we have successfully developed an …

A chemical investigation of some New Zealand honeys
… substances from a series of white clover type, manuka, ling/heather, thyme, nodding thistle, vipers bugloss, kamahi and willow honeys afforded chromatograms which serve to uniquely characterise the floral sources of the honeys. Correlation was sought between the occurrence of extractable organic …

The factors responsible for the varying levels of UMF® in mānuka (Leptospermum scoparium) honey
The variability in the level of the non-peroxide antibacterial component (UMF®) of mānuka honey produced in New Zealand was studied. A field analysis confirmed considerable variability existed in the honeys, and a number of hypotheses to explain this variability were proposed and examined. Nectar …

Chemical aspects of saponin bioactivity and ovine photosensitization diseases
… fraction (triketone oil) from East Cape Manuka oil were subjected to a bioactivity evaluation against a range of bacterial and fungal organisms using the agar gel well diffusion technique. A possible structure-activity relationship amongst the synthesized saponins is discussed. The …

Kinetics of Conversion of Dihydroxyacetone to Methylglyoxal in Honey
Mānuka honey contains a unique non-peroxide antibacterial activity which is highly sought after due to the perceived health benefits. Methylglyoxal (MGO) is the compound predominately responsible for this non-peroxide activity (NPA). Varying levels of dihydroxyacetone (DHA) are found in mānuka …
