New studies on the volatile compounds in propolis are growing rapidly. It's not surprising as the strength of propolis makes it a powerful, preventative and protective agent with complementary effects when combined with allopathic treatment.
Propolis Volatile Compounds: Chemical Diversity and
Biological Activity: A Review
Chemistry Central Journal, 2 May 2014
Propolis is a sticky material collected by bees from plants,
and used in the hive as building material and defensive substance. It has been
popular as a remedy in Europe since ancient
times. Nowadays, propolis use in over-the-counter preparations,
"bio"-cosmetics and functional foods, etc., increases.
Volatile compounds are found in low concentrations in
propolis, but their aroma and significant biological activity make them
important for propolis characterisation. Propolis is a plant-derived product:
its chemical composition depends on the local flora at the site of collection,
thus it offers a significant chemical diversity. The role of propolis volatiles
in identification of its plant origin is discussed. The available data about
chemical composition of propolis volatiles from different geographic regions
are reviewed, demonstrating significant chemical variability. The contribution of
volatiles and their constituents to the biological activities of propolis is
considered.
Future perspectives in research on propolis volatiles are
outlined, especially in studying activities other than antimicrobial.
