Propolis is a resinous hive product collected by bees. Propolis is a complex mixture of phenols, acids, alcohol and flavonoids. The aim of the present work is to study the effective components present in propolis and to confirm its biological activities. Four extracts from propolis were obtained by using different organic solutions. Further separation and identification were carried out by capillary gas chromatography and mass spectrometry(CGC/MS). The CGC/MS analysis on propolis extracted by different solvents resulted in more than 80 compounds being separated. Another 38 bioactive materials, including 6 alcohol, 5 phenols, 6 acids, 6 flavonoids and 13 others, have been identified.
