Leptosperin in Manuka Honey Testing

Leptosperin is a chemical marker that is only found in mānuka honey. It is difficult to synthesise, therefore it can be used as an authenticity marker to provide confidence that the mānuka is not adulterated. 

What is Leptosperin? 

Leptosperin is the first of potentially many mānuka-specific chemical markers used to verify the authenticity and proper labeling of mānuka honey. 

This naturally occurring compound is found exclusively in the nectar of mānuka plants and a few closely related species. Discovered and patented by Japanese researcher Kato in 2014, its presence in mānuka nectar was later confirmed by the UMFHA at the Apiculture Industry Conference in Whanganui, New Zealand. 

Leptosperin levels remain stable over time, making it a reliable indicator for determining whether honey is derived from mānuka nectar. This helps in accurately labeling honey as mānuka, a mānuka blend, or multi-floral. Additionally, measuring Leptosperin concentrations can detect potential adulteration, ensuring the integrity of mānuka honey. 

What is the Turnaround Time for Leptosperin Testing? 

Results will for routine testing are available the next working day and the same working day for urgent testing from receipt of sample.

Hill News August 2026 - Update from our MD, Dr Jonno Hill

As I write this, we are finishing the clean up after a complex and high-stakes piece of work which was delivered over the weekend – an upgrade to the power supply at our largest lab, located in Hamilton. This has been months in the planning, and included a full power shut down to the site, with generators used to keep essential operations running until the power was restored.
