Abstract

The composition and biological value of honey vary depending on its producing flora. The botanical, chemical and biological active properties of honey determine the geographical authenticity of the honey. In this study, geographic fingerprints of thirty Astragalus (Astragalus microcephalus Will.) honeys from Erzincan region were investigated. The honey consist of Astragalus pollen more than 65% and others were Salix spp., Cistaceae, Trifolium spp., Thymus spp, Rosaceae, Papaveraceae, Onobrychis spp. etc are followed. The characteristic color of the analyzed honeys was bright/light yellow, Hunter color values (L, a, b) were found to be as L: 72-78, a: 7-16 and b: 58-78, respectively. Total polyphenol content of the honeys was 38.20±4.60 mg gallic acid equivalent (GAE)/100 g, it was found to be rich in some phenolics such as chrysin, caffeic acid phenyl ester, myricetin, pinocembrin, luteolin, and gallic acid.
