In vitroantimicrobial activity ofPistacia lentiscusL. edible oil and phenolic extract

Abstract

Pistacia lentiscus L. is known in some Tunisian forest area by its fixed oil used in traditional medicine as an antiseptic product. This investigation is the first to study the antimicrobial activity of P.lentiscus edible oil and its phenolic extract. Oil was extracted from fruits harvested from six provenances located in Tunisia. The antimicrobial activity was tested using disc diffusion assay and the broth dilution method. Kbouch and Sidi Zid oils were most efficient (p < 0.003) against, respectively, Staphylococcus aureus and Aspergillus niger with an inhibition zone of 9.33 mm. The phenolic extract had the largest spectrum of sensitive microorganisms. The minimum inhibitory concentration and minimum bactericidal concentration results showed that all strains were inhibited by both oil and extract.

The Selective Interaction of Pistacia lentiscus Oil vs. Human Streptococci, an Old Functional Food Revisited with New Tools

“…The plant’s location, climatic conditions and soil composition could explain the fact that the Sardinian LBO activity against S. aureus described in our study was not found in previous studies performed using Tunisian LBO ( Mezni et al, 2014a , 2016 ).…”

“…Each part shows different proprieties: mastic gum (produced on the island of Chios) is active against Helicobacter pylori infection, while the leaf-essential oil affects different bacterial species including some oral pathogens such as: Porphyromonas gingivalis, Streptococcus mutans, Streptococcus gordonii, Fusobacterium nucleatum, Prevotella intermedia ( Pham-Huy et al, 1999 ; Koutsoudaki et al, 2005 ; Aksoy et al, 2006 ). The oil produced by pressing the berries represents the liquid fraction at room temperature and the antimicrobial activity of lentisk oil obtained from the berries (LBO) on Staphylococcus aureus and Aspergillus niger it has recently been reported ( Mezni et al, 2014a , 2016 ). At present, few studies exist on the interactions of LBO with microorganisms and on its antimicrobial mode of action.…”

Phytochemical screening, antifungal and antioxidant activities of three medicinal plants from Algerian steppe and Sahara (preliminary screening studies)

“…Our results are in agreement with previous studies. P. lentiscus is considered to be an antimicrobial plant [53,54], and ethanolic extracts of its fruits and leaves are used as ingredients in pork sausage to reduce microbial spoilage [55]. Some studies found that organic extracts of C. colocynthis are more active in comparison to aqueous extracts [47] and that hydromethanolic extracts are less toxic against F. oxysporum and its enzymes (CMCase, pectinase, and protease) [56] and exhibit a moderate antifungal activity against A. fumigatus DSM790 and A. niger DSM1988 [57].…”

“…Moreover, alphitolic acid a triterpenoid identified from leaves is a significant antibiofilm against S. mutans, a causative agent of human dental caries (Damiano et al, 2017). In the literature, several studies have proved the inhibitory effect of phenolic compounds and flavonoids on microbial strains; it has been reported that Gram-positive bacteria are hypersensitive to herb essences than Gram-negative due to hydrophobic lipopolysaccharide in the outer membrane that protects various factors (Mezni et al, 2015;Ferreira et al, 2012).
