Abstract

Propolis
is acomplex material collected by honeybees from plant and tree buds, resins
and exudates. In the last recent years several research indicated that Algerian
propolis possess a large spectra of biological activities such as
antibacterial, antifungal, antioxidant and anticancer activities. Few studies
on chemical composition of Algerian propolis indicate the presence of two
propolis type mainly poplar¹ and Mediterranean type^2,3
with caffeate esters and flavonoids as main constituents of poplar type while
Mediterranean type is rich on labdane and clerodane diterpes¹.

            The objective of the present study
is the determination of chemical composition of propolis sample collected from
jijel. Chemical investigation allowed the isolation of 12 Compounds. Their
structures were identified on the basis of spectral data (¹H-NMR and
¹³C-NMR) and MS data and comparison with literature. All isolated
compounds are flavonoids. Among the identified flavonoids pinocembrin,
pinostrobin and galangin-3-methyl ether indicate that the studied propolis is a
polpar type propolis.
