Physicochemical characteristics and antioxidant capacity of everlasting, Helichrysum italicum (Roth) G.Don, honey

Everlasting, Helichrysum italicum (Roth) G. Don, is aromatic and therapeutic plant used in folk medicine since ancient times. It is distributed around Mediterranean region and grows in arid, stony and sandy areas. The data of typical Mediterranean honeys characterization (e.g. sage, rosemary, lavender) are available in the literature, but not for the everlasting honey. Objective of this preliminary study was to determine physicochemical characteristics, antioxidant capacity and total phenol content of everlasting honey. Pollen analysis was performed and the following physicochemical characteristics were determined: moisture, electrical conductivity, HMF content, diastase activity, pH and acidity, specific rotation and colour. Antioxidant capacity was determined by FRAP (Ferric Reducing Antioxidant Power) and DPPH (2, 2-diphenyl-1-picrylhydrazyl) methods, and total phenol content by modified Folin-Ciocalteu method. The results showed that everlasting honey has high diastase activity and total acidity, as well as antioxidant capacity and total phenol content.
