Elucidating the molecular basis of dihydroxyacetone (DHA) production in Leptospermum nectar
Mānuka (Leptospermum scoparium) nectar contains variable amounts of dihydroxyacetone (DHA), a triose sugar that is the precursor to methylglyoxal (MGO), the antimicrobial compound underpinning the high value of mānuka honey and forming the basis of the Aotearoa-New Zealand honey industry. This …

Extraction of bioactive compounds from New Zealand Manuka leaves (Leptospermum scoparium) using emerging technologies
… 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 activities. …

The factors responsible for the varying levels of UMF® in mānuka (Leptospermum scoparium) honey
… were proposed and examined. Nectar derived from Leptospermum scoparium (mānuka), was confirmed to be the source of UMF®. The dilution of mānuka honey with nectar derived from other floral sources was found to proportionally reduce the UMF® in monofloral mānuka honey. The utilisation of the …

Assessment of Seedling Recruitment Under Manuka (Leptospermum scoparium) and Kanuka (Kunzea ericoides) Plantings at Shakespear and Wenderholm Regional Parks
… cuniculus and Rattus rattus on seedlings under Leptospermum scoparium and Kunzea ericoides plantings in two Auckland Regional Council Parks (ARC), Shakespear and Wenderholm. The number of woody seedlings that established over a 17-month period was recorded. Gaps within the same Leptospermum …

Investigation into the effects of parasitoids on a gall midge Dasineura sp. (Cecidomyiidae), a biological control agent of Australian myrtle, Leptospermum laevigatum
Leptospermum laevigatum is one of the top five invading species in the fynbos biome and its biocontrol is of high conservation priority in the Western Cape. The first species used as a biocontrol agent was a leaf-mining moth Parectopa thalassias that became established and wide-spread. The second …

The role of certain mortality factors in the underperformance of Aristaea (Parectopa) thalassias (Meyrick) as a biological control agent of Leptospermum laevigatum F. Muel.
Leptospermum laevigatum is indigenous to the coasts of south and central New South Wales in Australia. It has become invasive in South Africa since its introduction in the 1800s, competing with the native fynbos across the coastal regions of the Western Province and into the Eastern Cape Province. …

A CONTRIBUTION TO THE STUDY OF BIOCONTROL AGENTS APITHERAPY AND OTHER POTENTIAL ALTERNATIVES TO ANTIBIOTICS
… high non-peroxide 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 …

Argininderivatisierung und 1,2-Dicarbonylverbindungen in Lebensmitteln
… 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 Honigen deutscher und …

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 …
