Abstract(s)
The volatiles from 24 propolis samples collected from different geographical locations in Morocco
were evaluated. Propolis volatiles isolated by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS). Cluster analysis based on
propolis samples’ volatile chemical composition defined two main uncorrelated clusters. Cluster I,
with 23 of the 24 samples analyzed, included three subgroups, Ia, Ib1 and Ib2, dominated by βeudesmol (11–30%), cedrol (7–40%) and n-tricosane (6–34%), respectively. Cluster II included just
one sample, with ar-curcumene (32%) as the main component. The results obtained contributed
to increase the knowledge on the chemical composition and variability of Moroccan propolis
samples. The volatile profile of these samples was distinct from those of Algeria, Canary Islands
and Ethiopia, the sole African propolis volatiles studied so far.
