One must remember that propolis compounds are a
specific to place of origin, this particular compound
(Artepillin C found in Brazilian propolis) may not
necessarily be found in propolis of other origins. 
Spectrometry analysis of propolis from different
locations has shown that the propolis compounds are
very different depending on their place of origin.

To identify the plant origin of Brazilian propolis
(green propolis) scientists observed the behavior of
honeybees in Minas Gerais State of Brazil. They found 
that honeybee workers bit and chewed leaves of the
plant, Baccharis dracunculifolia, packed the material
into their pollen basket, brought it back to their
nest, and used it as propolis.  Scientists then
collected the leaves of B. dracunculifolia and
propolis, and compared their constituents by liquid
chromatography-mass spectrometry analysis.  They
discovered that the compound artepillin C  (known for
it’s antitumor activity) to be contained in both B.
dracunculifolia and propolis collected by honeybees,
and that there was no difference between the chemical
constituents of the ethanol extracts of B.
dracunculifolia and those of propolis collected there.
This indicated directly that the plant origin of
Brazilian propolis is B. dracunculifolia.

Here’s a file that includes info on the matter and a
photo of B. dracunculifolia.
