Propolis is a natural product derived from plant resins collected by honeybees and used in the beehive as a construction and defensive material. The broad spectrum of biological activities is dependent on the chemical diversity of its composition which is determined by the floral sources at the site of collection. For the first time, the chemical composition of Guinean propolis as well as its physicochemical properties, phenolic composition, and antioxidant activity was assessed. Eight compounds were identified through LC/DAD/ESI-MS n , mostly isoflavonoids, resembling Nigerian and Brazilian red propolis from the genus Dalbergia.
