Phytochemical, antioxidant and antibacterial activities of the aqueous and ethanol extracts of Pinus halepensis

The present study was designed to evaluate the phytochemical screening of different extracts(Aqueous and ethanol) of the needles of Pinus halepensis; to explore their antioxidant activities with the different tests and to determine their antibacterial proprieties. Our results revealed that these extracts contain polyphenols, flavonoids and tannins. Then, the same extracts(Aqueous and ethanol)present the highest content of total phenol and tannins which were of order respectively(735.41 ± 0.09 pgGAE/ mg of extract and 49.60 ± 0.012 pg CE /mg of extract compared with other extracts. The results showed alsothat the different extracts had an important antioxidant andantibacterial activity. Overall, the richness of the different extract of Pinus halepensis with total polyphenols, flavonoids and tannins explained the biologic propriety of this plant.
