Propolis, a natural resinous product collected by honeybees from the buds and exudates
of various plant sources, has been used empirically as a traditional remedy in folk medicine
for centuriesIt is well known for potential health benefit and is reported to possess valuable
biological activities. Recently, propolis has been extensively marketed by the pharmaceutical
industries as an alternative medicine and as the health-food in various parts of the world. This
study determines the antioxidant and anticholinesterase activities of various extracts of
algerian propolis In addition,the total phenolic and flavonoid contents were also determined
spectrophotometrically. Antioxidant activity was tested by using five complementary tests.
The in vitro anticholinesterase activity was tested against acetylcholinesterase (AChE) and
butyrylcholinesterase (BChE) enzymes. The current study has shown that ethyl acetate
extracts exhibited good lipid peroxidation inhibitory activity The DPPH, ABTS, and
CUPRAC assays supported this activity.the petrolum ether and chloroforme extracts indicated
good anticholinesterase activity.These results showed that the tested extracts obtained from
propolis, can be considered as sources of food additives, as well as moderate
anticholinesterase agents
