Abstract: This work presents a contribution to the detection of biological activity of some secondary metabolites of Teucrium polium geyrii, which is a Lamiaceae plant family of Tamanrasset (southern Algeria). The plant was subjected to two types of phenolic compounds extraction, maceration and Soxhlet apparatus. The semi-quantitative analysis of total phenols and flavonoids (phenolic extracts), was performed by colorimetry. It showed that the ethyl acetate extract obtained by maceration contains the largest amount of total phenols, 89.05±0.50 mg/g equivalent of gallic acid, as well as the rate of flavonoids with 0.45±0.001 mg/g equivalent of vitexin. The antibacterial activity carried on bacterial strains pathogenic and alterations, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus cremoris, Clostridium perfringens, Klebsilla pneumoniae, Escherichia coli and Proteus mirabilis, by Aromatogram method, showed that the extracts tested are endowed interesting antibacterial activity with inhibition zones can reach 3.4±0.3 cm in diameter on Proteus mirabilis.
