Abstract

The phenolic compounds, flavonoids in particular, are very frequent in
the plant kingdom with many beneficial properties. Some of these compounds are
present in exudates or buds of plants. They appear in propolis as a consequence
of the collection and transformation by specialized honey bees in the hive. The
aim of the study is the determination¹ of phenolic compounds by
UPLC-MS/MS and UPLC-PDA in methanolic extracts² of 134 samples of
propolis from Castilla y León (North and Centre of Spain). Such samples were
gathered using high density polyethylene mesh for food use which placed in
Langstroth beehive from April 2011 to August 2012.

The results obtained reveal the interesting source of
bioactive compounds of the North and Centre of Spain propolis, being the most
significant caffeic acid and its derivatives (CAPE and isoprenyl caffeate),
chrysin, pinobanksin, p-coumaric acid, galangin and kaempferol; other compounds
identified only in some samples were benzoic acid, trans-ferulic acid,
taxifolin, luteolin, sakuranetin, apigenin+genistein and eriodictyol.
Furthermore, the content of CAPE and isoprenyl caffeate may restrict its use,
for the food and pharmaceutical industry, since they are considered allergens³.
