Leptosperin is the first of what could be a number of Manuka specific chemical markers, which are used to identify Manuka honey for authenticity and labelling purposes.

Leptosperin is a naturally occurring chemical, found only in the nectar of Mānuka plants (and a few very close relatives).  It was first identified (and patented) by Japanese researcher Kato in 2014*, and later that year its presence in Mānuka nectar was reported by the UMFHA and Analytica Laboratories at the Apiculture Industry Conference in Whanganui, New Zealand.  Leptosperin concentration is stable over time, and therefore measuring its concentration in honey is a good way of identifying whether the honey comes from Mānuka nectar, and whether it can be labelled as Mānuka, or a Mānuka blend, or as a multi-floral honey.

Leptosperin concentrations have the ability to highlight cases of possible adulteration of honey to look like Mānuka.

At this stage, UMFHA holds the NZ license for the use of Leptosperin testing in Mānuka honey, and ask us to collect a royalty for all tests carried out.  UMFHA members pay a $5 + GST per test royalty and non-members pay a $10 + GST per test royalty.  Royalties are collected by Analytica for payment in full to the UMFHA.

A sub sample of honey is extracted in ultra-pure water, diluted and analysed by Ultra Performance Liquid Chromatography (UPLC).

Analytica developed the leptosperin method on behalf of Unique Manuka Factor® Honey Association (UMFHA) and was the first lab in New Zealand offering this testing.
