Comparative antibacterial activities of the essential oils of stems and seeds of Pituranthos scoparius from Algerian septentrional Sahara

Abstract

and B. Ait-Kaki 2Pituranthos scoparius (Coss. & Dur.) Schinz (Umbelliferae) is a saharian species [1] used in traditional medicine for the treatment of asthma and rheumatism [2][3], Touareg people also use it in food as aroma for meal and bread [3]. The GC and GC/MS analysis of the essential oils of Pituranthos scoparius stems and seeds, collected from Ghardaia [4] (septentrional Sahara) during spring, allowed us to identify the respective components with relative percentages which appeared to be different from those reported from the species collected during winter at Ain Diss [5] (presaharian). The comparative percentages of the major components (more than 3%) of the stem and seed oils for each specimen (saharian and presaharian) are given in Table1.The species Pituranthos scoparius has not been the subject of biological studies. We report here the comparative antibacterial activities of the essential oils of stems and seeds of the species collected at Ghardaia, using the disk diffusion method. The MIC (minimum inhibitory concentration) values are given in Table 2-3. Both of the essential oils inhibited the growth of the tested strains, but the stems oils inhibited remarkably the growth of the microorganisms namely Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis, and Klebsiella pneumoniae at the respective concentation levels 1mg/ml, 2 mg/ml, and 16mg/ml with 32 mm, 30 mm, and 28 mm inhibition zone diameters while the seed essential oil showed lowest MIC values with Proteus mirabilis, Pseudomonas aeruginosa ATCC 27853, and Staphylococcus aureus ATCC25923 at 0.156 mg/ml, 1.25 mg/ml, and 20 mg/ml with 30 mm, 28 mm, and 28 mm inhibition zone diameters, respectively.

Volatile compounds and biological activities of aerial parts of <i>Pituranthos scoparius</i> (Coss and Dur) Schinz (Apiaceae) from Hoggar, southern Algeria

“…To the best of our knowledge, there are very few reports available regarding the antimicrobial activity of P. scoparius essential oil. Results obtained by Boutaghane et al revealed that the essential oils extracted from stems and seeds of species collected from the region of Ghardaia (Algeria) inhibited the growth of the microorganisms namely Pseudomonas aeruginosa, Proteus mirabilis, and Klebsiella pneumonia [21].…”

<i>In vitro</i> antibacterial activity of <i>Pituranthos scoparius</i> from Algeria

“…There is a distinct possibility that active principles, with differing mechanisms of action, may be present in a crude extract, thus slowing the onset of antibiotic resistance. Boutaghane et al (2004) reported a comparative study on the antibacterial activities of essential oils from stems and seeds of species collected from the region of Ghardaia (Algeria). These two kinds of essential oils inhibited the growth of the tested strains, but the seed essential oil showed lower MIC values with Proteus mirabilis, Pseudomonas aeruginosa ATCC27853, and Staphylococcus aureus ATCC25923 at 0.156 mg/ml; 1.25 mg/ml, and 20 mg/ml respectively.…”

Antioxidant effect induced by the essential oil ofPituranthos scopariusin a formulation of a whey spread emulsion

“…Reports of the chemical profile of the essential oils of P. scoparius are very limited. We report mainly the work of (Vérité, Nacer, Kabouche, & Seguin, ) on stems and seeds of P. scoparius (Boutaghane et al, ) on their antibacterial activities and more recently the work of (Lograda, Ramdani, Kiram, Chalard, & Figueredo, 2013) on the variation of the essential oils compositions of P. scoparius collected from different locations in Algeria.…”

“…The traditional use of the plant in folk medicine concerns applying it in poultices to the head for headaches (Bellakhdar, 1997). Boutaghane, Nacer, Kabouche, and Ait-Kaki (2004) reported an antibacterial activity for the seeds and stems of P. scoparius. Reports of the chemical profile of the essential oils of P. scoparius are very limited.…”
