Abstract
Schinus molle L. commonly refered to as peppertree belongs to the Anacardiaceae family.
All parts of this shrubby tree have high oil and essential oil content that produce a spicy scent.
The berry-like fruits, which have a pepper flavour, are used in beverage in some South America countries where they are dried and ground for a pepper substitute in the tropics.
Throughout South and Central America, peppertree is reported to be an astringent, antibacterial, diuretic, digestive stimulant, tonic, antiviral and wound healer.
In Algeria, S. molle is used as urban greening tree throughout the country rather than medicinal plant.
Despite that the medicinal potential of plants in Algeria is considerable, knowledge of this area and studies on the biological activities of these plants remained scarce.
The aims of this study were to identify and determine the antimicrobial activities of EO extracted from the aerial parts of S. molle (leaves and berries).
The essential oils (EO) extracted from the leaves and the berries of Schinus molle were analysed by gas chromatography-mass spectrometry (GC/MS) and 67 constituents were identified.
The major constituents of EOs were
-phellandrene (24, 32%), limonene (21, 62%), 
-myrcene (17, 76%), -pinene (4, 13%) for leaves, and -phellandrene (23, 28%), limonene (21, 04%), 3-carene (17, 35%) and 1R- pinene (3, 98%) for berries.
Secondly, the present study was conducted to evaluate the in vitro antimicrobial activity of EO. For this purpose, paper disc-diffusion method and micro dilution test were used.
As far as the antibacterial activity is concerned the leaves EO exhibited higher ones against B. subtilis, average ones against S. epidermidis and C. albicans, Low ones against E. coli, Pseudomonas sp. and no effect against Agrobacterium.
The minimum inhibitory concentration (MIC) EO of leaves revealed that B. subtilis, S. aureus, S. epidemidis and C. albicans had a value of 6.25%, whereas E. coli and Pseudomonas sp. had a value of 50%.
The berries EO exhibited average to low activity against B. subtilis, S. epidermidis, E. coli, S. aureus and C. albicans, respectively.
The (MIC) values of EO of berries revealed that S. epidermidis had the MIC of 25%, whereas B. subtilis and S. aureus had the MIC of 50%.
The MIC of C. albicans is 100%.
