Abstract:
Propolis is a natural substance that is collected by honeybees from
buds and flowers of some specific plants, and it is used in beehive as a
protective barriere against enemies. Propolisul was used by popular
medicine in many world`s areas and there were reported different biological
activities, such as: antibacteriane, antiinflamatoary and anticancerouse. For
this reason, propolis is intensively used in alimentary and beverage industry
for the impruvement of it`s natural quality and for the prevention of certain
deseases, such as inflamations, cardiovascular deseases, diabetes and
cancer.
Propolis is one of the most valuable apicol product, rich in flavons,
terpene, steroid, aminoacids and different mineral constituents.
The paper presents the phytocidic activity of the propolis (powder)
and the aqueous extract of propolis in different quantities or concentrations
in the case of wheat, corn, rice, and barley.
The aqueous extract of propolis was obtained by refluxing 4 hours
and filtering. The cereals were cultivated on hydrophyllic cotton with the
propolis samples. This study was performed for 11 days and the higher
phytocidic activity was observed in the case of corn, followed by wheat. The
lower phytocidic activity was observed in the case of rice and barley.
As a consequence, we can generally notice a significant increase of
inhibition concerning the wheat, maize and the oat samples, and even less
significant concerning the barley samples not only on the propolis dust
administration, but also when treating it using a watery propolis extract.
