Characteristics of Propolis in Egypt, UAE and Chile

Chemical Composition of Egyptian and UAE Propolis
Pakistan Journal of Pharmaceutical Sciences, 2006 Jan;19(1):58-61

The chemical composition of propolis samples obtained from Behera, Egypt and Dubai, UAE, have been investigated by GC-MS and thirty four compounds have been tentatively identified. Some of these compounds have not been reported previously in Egyptian propolis from different regions. The Egyptian sample contains a high amount of aliphatic (13.7%) and aromatic (14.4%) acids. The alcohols, phenols and esters account for about 17.0% of the total content analysed. Some anthraquinone and flavone derivatives have also been detected (10%). The UAE sample is characterised by the presence of a high content of aliphatic acids (15.2%) and a low content of aromatic acids (4.3%)…

Characteristics Organoleptic and Physicochemical Propolis in the Province of Nuble, VIII Region-Chile
Archivos Latinoamericanos de Nutrición, 2005 Dec;55(4):374-9

Propolis ("bee-glue") is a gummy resinous substance elaborated by honey bees (Apis mellifera) from different types of plant resins. The chemical composition of propolis is very complex and variable as it depends on the botanical source and the environmental conditions prevailing at the location where the resin is collected by bees. The objective of this study was to determine the propolis organoleptic and physicochemical properties of different types in the Province of Nuble (VIII Region, Chile)…

Results showed that propolis extracts from coastal sites are better quality than those collected at mountain skirts, and these in turn are better than propolis obtained from the Central Valley…
