IN VITRO EVALUATION OF BIOLOGICAL ACTIVITIES OF PISTACIA LENTISCUS AQUEOUS EXTRACT
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 11
Abstract
Objective: The aim of this study was to study the antioxidant potential and the antibacterial activity of leaves aqueous extract of Pistacia Lentiscus as well as the protective effect of this extract against the haemolysis in hypotonic condition, in oxidative stress and in the existence of saponin injury.Methods: We studied the antioxidant capacity through the DPPH assay, H2O2 scavenging activity, Ferric-reducing power (FRAP) assay, total antioxidant assay and the antibacterial activity using the disc diffusion method. We also investigated the haemolytic activity with the spectrophotometric method.Results: The result showed that the aqueous extract had a good antioxidant capacity, which was calculated as IC50. IC50 of the aqueous extract was found to be 9.89±0.7µg/ml for DPPH scavenging, 200±18.02µg/ml for H2O2 scavenging assay, 54.06±12.66µg/ml for Ferric-reducing power (FRAP) and 500±22.3 µg/ml for total antioxidant capacity. The aqueous extract also inhibited the growth of the tested bacterial strains with a maximum inhibition zone of 30.33±5.5 mm observed on Pseudomonas aeruginosa for wood-seed and a moderate activity against all other strain. The haemolytic analysis showed that the aqueous extract is not toxic for the human erythrocytes and protects them against the oxidative and osmotic stress and also against saponin injury.Conclusion: The results of our study suggest that the aqueous extract of leaves of Pistacia lentiscus possess potent anti-haemolytic activity, are a good source of natural antioxidant.Â
