Most of Yemeni honey have a locally and internationally Fame. Six of Yemeni honeys were selected according to geographical and floral sources and their fame such as (Osymi sidir, Dawani sidir, Jardai sidir, Salam Tohamah, Somara Shabwah and SSAl Tawr Albahah). Physic- chemical properties were conducted on tri replicate, according to chemical standards methods. The results showed that all honeys were dark color; the mean results were as following: the highest value of pH was 3.71 of SSal Honey, while the least mean value was 5.3 of Sidir honeys; total acidity was on limit for all, the highest value of moisture was found on SSal, whereas Sidir honeys showed the least mean value 13.62; Hydroxylmethaylfurfural (HMF) of all studied honeys were on limit that is less than permitted value 40 mg/100g; Daistase number of all were on permitted limit except Somra honey that showed 6 shade units; values of sugars analysis were found on permitted limit except Somra was 16 g/100g; electrical conductivity of Jardani sidir honey was the highest mean value 1220, while Somra honey had the least value 544; as well as in comparison of total phenolic compound results, Jardani Sidir had the highest mean value 274.3 mg/100g of tannic acid, while Somra had the least mean value 82.01 g/100g of tannic acid. All studied honeys were in conformity to local, regional and international standards except Somra honey that has non-conformity to them.
