✦ Synopsis

The content of the Ñavonoid kaempferol in di †erent experimental rosemary honey samples produced in Arago n (Spain) and in some commercial rosemary honey samples produced in di †erent Spanish regions was evaluated by HPLC. The content ranged between 0É33 and 2É48 mg kg~1 of honey. Nectar has been suggested recently as the origin of this Ñavonoid. Rosemary pollen contained kaempferol 3-diglucoside and 3-glucoside, and therefore could be an alternative source for the kaempferol found in rosemary honey. However, there was no correlation between the kaempferol present in honey and pollen content. This suggests that the contribution of pollen Ñavonoids to the pool of Ñavonoids found in honey is very small, and that the search for phenolic markers of the botanical origin of honey should be addressed to the identiÐcation of nectar Ñavonoids or other nectar constituents.
