Abstract
The chemical profiles of propolis hydroalcoholic extracts from different regions of Morocco were studied by gas chromatography coupled to mass spectrometry after silylation. Samples from Khamissat and Imouzzer belong to the poplar type, as typical poplar flavonoids predominated. Propolis from Rabat also contained high percentage of flavonoids, but had significantly lower amount of phenolic acid esters and contained no pinobanksin-3-O-acetate. Propolis from Bhalil demonstrated a profile rich in diterpenes (74.3%), and is a typical Mediterranean propolis sample. All samples had the capacity for inhibiting glucosidase and amylase enzymes, as well as the capacity for scavenging free radicals and preventing lipid peroxidation. Both activities were significantly higher in the flavonoids-rich samples.Entities:
