Summary In this study a total of twenty Moroccan honey samples were analysed and botanically characterized: these included sunflower ( Helianthus annuus L.), crucifer ( Diplotaxis sp.), carob tree ( Ceratonia siliqua L.), loeflingia ( Loeflingia sp.), heather ( Erica sp.), mint ( Mentha sp.) and wood sage ( Teucrium scorodonia L.). Unifloral honeys were considered as such whenever the dominant pollen was found at over 45% of total pollen, except for sunflower, mint and wood sage types of honey where a finding above 20% of Helianthus annuus , Mentha sp. and Teucrium scorodonia pollen, respectively, was enough to typify them. The samples have been analysed to determine: moisture, pH, acidity (free, lactonic and total), hydroxymethylfurfural, diastase activity, proline, electrical conductivity, ash and mineral content, sugar composition, and colour variables ( L *, a *, b *, C * ab , h ab ).
