Brazilian Propolis Evaluated for Key Component

Validated Method for the Quantification of Artepillin-C in Brazilian Propolis
Phytochemical Analysis, Early View (Articles online in advance of print)

Abstract: Brazilian propolis contains several phenolic compounds among which 5 diprenyl-4-hydroxycinnamic acid (artepillin-C) is commonly found in areas where flora is rich in Baccharis species.

The quantification of artepillin-C has become an important factor as an indicator of Brazilian propolis quality and the compound may be used as a chemical marker for quality control in exportating green propolis.

This work was to validate the method and evaluate the content of artepillin-C from 33 samples collected in different Brazilian regions…

Propolis from the southeast region presented the highest level of artepillin-C (5.0-11.0%). (Propolis) from the northeast region did not show any artepillin-C.
