In the present work, the results of analysis of 10 Libyan honey samples, representing various floral honeys, collected from Benghazicity during different seasons in 2009-2010 were demonstrated. All samples were examined for the physicochemical quality parameters, phenolic compounds and heavy metals contents. The moisture; optical density (O. D.); electrical conductivity; water insoluble solids; ash content; pH; total acidity; hydroxylmethyl furfural (HMF); sugar contents and phenolic compounds content were detected according to AOAC 1990 -Official Methods and reference methods. The results were compared with Libyan Standard Legislation and the European Standard Legislation . The obtained results indicated that the quality of the tested Libyan honey samples were very good and worth to the world standard properties of honey. Even more, the tested Libyan honey samples have high level of phenolic compounds content. On the basis of heavy metals content, three metals were determined (Cadmium, copper and lead) using atomic absorption spectrophotometer. The level of each metal-content was variable, which may be due to the conditions of processing, packing and storage conditions of Libyan honey samples.
