Characterization Of Bioactive Compounds In South-western Algeria Propolis Samples

The prepared hydro-alcoholic extract of propolis samples, which are harvested in Rebahia (Saida, Algeria), were analyzed by gas chromatography-mass spectrometry to provide 50 volatile bioactive compounds. The major compounds had been found, to know: Terpenoids (spathulenol 2.01 %, 1-dotrontanol 1.25 and trans-2-hexen-1-ol 1.03 %), Polyphenols (carvacrol 0.71 % and thymol 0.49 %) Hydrocarbons (1,4-diethyl cyclohexane 8.22 % and 1-docecane 12.13 %) and organic acids (9,12-octadecadienoic acid 1.27 %).
