From natural power to scientific control


The classic extraction of Propolis consists in the dissolution of raw Propolis in 80% alcohol content which extracts 75-80% of the polyphenols but however, melt uninteresting resins and waxes too.

Thanks to Dynamic Multi Extraction patented method, M.E.D.® Propolis extracts preserve the total of active molecules present in raw Propolis, not only the flavonoids but also phenolic acids. Moreover, Dynamic Multi Extraction allows to obtain the glycosylated fraction of polyphenols in dry extracts microencapsulated in Arabic gum useful to increase the hydro dispersion.

M.E.D.® Propolis extracts are pure from inactive resins and rich in polyphenols.


Polyphenols are a family of about 5000 molecules widely present in the plant world. Amongst Polyphenols, there are “sub-families” which differ from each other because of the number and characteristics of the phenolic units. These structures have an influence on the chemical and physical properties amongst which solubility. Standard method of extraction of Polyphenols from Propolis involve the use of a single solvent. The result is a partial extraction.

The Dynamic Multi Extraction (M.E.D.), after an HPLC analysis of the starting raw material, uses various concentrations of solvent during the whole production process thus extracting Polyphenols with different solubility and especially flavonoids, phenolic acids and glycosilated fractions, separating them from those resins that can reduce their activity.

The strength of B Natural products is given by the richness and quality of bioactives.
