Brazilian Green Propolis
Brazilian green propolis is a specific type of propolis, which contains Baccharis dracunculifolia resin, as the main source. The Brazilian Green Propolis health benefits mainly underline those of the plant, in addition to the ones we commonly find in any other propolis, no matter the botanical source.
Propolis is composed mainly by the plant resins and exudates that bees gather. Bees add wax, and some secretions and pollen to it. The composition of propolis depends on its botanical and geographical origin, even weather and hive. The plants that are harvested by bees are so different, that the composition of propolis will never be the same. So, besides the usual dark brown propolis, propolis can also be green, red, black, and with white hues.
And, it is quite astonishing, that while the composition of the different type of propolis differs greatly depending on its botanical origin, their biological effects are very similar.
Baccharis dracunculifolia DC (Asteraceae) is the main botanical source used by honeybees to produce Brazilian green propolis. Baccharis dracunculifolia is a medical plant found in Brazil. It is mainly used for its antiulcer and anti-inflammatory properties.
The overall content of this propolis type is similar to the poplar propolis, basically containing balsamic and non balsamic components. It contains a main part of plant derived substances and minor part of bee and pollen derived substances. The chemical composition is, however very different.
The balsam part of poplar propolis originates from the collected glue, while the non-balsamic constituents are added by the bees. The typical components of poplar propolis are the phenolics: flavonoid aglycones, (flavones and flavanones), phenolic acids and their esters.
The typical compounds of Brazilian propolis are prenylated derivatives of p-coumaric acid and of acetophenone, as well as diterpenes and lignans. The flavonoids are different from those in ‘poplar type’ propolis.
On Dec 2014, Society of Chemical Industry published the Composition of the volatile fraction of a sample of Brazilian green propolis and its phytotoxic activity, made by Fernandes-Silva CC et at, from the University of São Paulo, São Paulo, Brazil. The study shows an analyzes of chemical composition of green propolis and evaluate the phytotoxic activity of the volatile fraction of a sample of Brazilian green propolis.
The chemical composition of the volatile fraction of this Brazilian green propolis is different from the other propolis. According to the study, the “main constituents are the phenylpropanoid 3-prenylcinnamic acid allyl ester (26.3%) and the sesquiterpene spathulenol (23.4%). Several other sesquiterpenes and phenylpropanoids, in addition to linalool and α-terpineol (monoterpenes), were also detected.”
