This study consists in a contribution to the valorization of the vegetable oil of the fruit of the lentisque Pistacia lentiscus L. a plant very adapted in the north-east of Algeria. We carried out harvests of the oil traditionally extracted by the rural populations at the levels of the three zones of studies, on which physicochemical analyses (color, moisture, index of acidity, index of peroxide, phosphatide, index of saponification) were realized the physico-chemical parameters of the collected oil were values corresponding to international standards and generally reflecting the good quality of oil, with the exception of the values of acidity index. this physico-chemical study is for the qualitative evaluation taking into consideration its origin (genotype X environment interaction) As the vegetable oil of this plant is a natural cure well known in traditional medicine in Algeria we have performed antimicrobial tests on three strains Pseudomonas, Staphylococcus aureus [Cocci (C+)], Klebsiella pneumoniae [Bacillus (B+)] and antifungal on Verticillium sp, Pythium sp, Phytophthora sp. For the purpose of highlighting the various uses of Pistacia lentiscus. The results reveal the ineffectiveness of all oils against all the bacterial strains tested. On the contrary, the antifungal study shows activities were observed with the oils of the three regions.
