Abstract

Volatil constituents of Algerian propolis

Author(s): Amar Zellagui

Hydrodistillation of three Algerian propolis collected in different locations of east of Algeria (Elmalha, Benibelaîd and Kaous) afforded a yellowish oil in a yield of approximately 0.03% to 0.11%. A total of 54 compounds were identified across all the samples representing about 74% of total content of each sample. Components were mainly monoterpenes, sesquiterpenes, acids and alkanes. GC-MS analysis indicated that the predominant components of the essential oil of propolis of El-malha were 2-hexenal (4.85%), myristic acid (2.03%), linoleic acid (1.86%) and (-)-spathulenol (1.6%). Nevertheless the predominant components of the essential oil of propolis of Benibelaîd were isooctane (3.89%), linoleic acid (2.18%), undecane (2.03%), myristic acid (1.65%), hexadecane (1.14%), p-cymene(1.21%), palmitic acid (1.05%) and 4-terpineol (1.03%). The major constituents of the essential oil of propolis of Kaous were 2-hexenal (11.15%), myristic acid (5.66%), linoleic acid (5.16%), carvacrol (4.47%), alpha-cedrol (2.57%) and pcymene (1.27%).
