Bee collected pollenis usually composed of poIlen species from variolls plants, this feature enhances the nutritional balance af the product. Even some species were widely studied [2], tnere are many others whose cOl11position remains unknown Iike C. saliva, one of the mos. abundant in honey-bee collected poIlen produced in the Parque Natural do Montesinho. ln the present communication we describe GC-MS stlldy of lipophil'ic extracts of two pollen species profusely existent in the mentioned region, C. saliva and C. ladanifor1.ls , Sampies were' col!ected with pollen-traps attached to lhe beehive entrance and were keptin the pollen-trap for no more than 48 h. Aner collection the polIen was Iyophilized and sorted into species-specific pollens', attertding to their color and microscopy patterns. Their composition in terms of lipophilic components, namely saturated and unsatllrated fatty acids, alkanes and stel"Ols will be presented and discussed.
