There are a few studies about characterisation of GTXs in mad honey produced from R. ponticum. This study quantified basic properties including concentrations of GTX I and GTX III in mad honey samples collected in three consecutive years. Although the chemical composition of mad honey varied annually depending on the production year, mean GTX I and GTX III contents were estimated at 20.4 +/- 1.69 and 8.20 +/- 1.93 mg/kg, respectively. The concentrations of GTXs did not change significantly during storage of 6 months. (C) 2014 Elsevier Ltd.
