Author(s): WAFA NOAIOIA

In this study, The Montaigne of boutaleb contains a plant heritage characterized by the presence of several species that possess medicinal properties. The methanolic and aqueous extract of the leaves of Pistacia lentiscus L. are prepared, the yield of the methanolic extract is 2, 99 with percentages 37.2% and the yield of the aqueous extract is 0.98 g with percentages 19.6%. The total dosage of polyphenols and flavonoids in the methanol extract is 38.27 ± 6.30 mg EAG/g extract and 9.80 ± 0,160, mg EAG/g extract, respectively. The total dosage of polyphenols and flavonoids in the aqueous extract is 26, 76 ± 2.47 mg EAG/g extract and 4, 15 ± 0.09 mg EAG/g extract, respectively. The effect of aqueous and methanolic extracts of mastic leaves was evaluated using the DPPH test. both extracts have shown a weak trapping effect towards the free radicals with an IC50 68.27 ± 9.96 μg/ml and with an IC50 72.92 ± 9,43 μg/ml respectively, then weak activity antioxidant. The antibacterial activity of the methanolic and aqueous extract of the leaves of Pistacia lentiscus is low significant. The aqueous and methanolic extract of mastic leaves possessing a very strong anti-inflammatory activity to protect the membrane of human blood red blood cells.
