Composition chimique et activités antioxydante, antimicrobienne et insecticide de l’huile essentielle de Juniperus phoenicea
Written by sctunisie no commentsThe essential oil composition of the leaf of Juniperus phoenicea from region of Medenine (The south of Tunisia) was investigated by GC, GC-MS. 27 constituents were identified correspond to 84.63% of the total oil. The major components are α-Pinene (59.11%), Linalool (3.3%), Germacrene D (1.55%) and Germacrene B (3.22%). Antioxidant action of this essential oil is proved in vegetal oil (soybean) and was effective in stabilizing lard against oxidation. Its activity is compared to that of δ-tocopherol. This oil has been tested for antimicrobial activity against two bacteria (Klebsiella oxytoca, Lactobacillus plantarum), yeast (Saccharomyces cereviseae) and fungi (Geotrichum candidum). Insecticidal properties of Juniperus phoenicea essential oil were investigated against Tribolium confusum insect pest of stored grains. This oil exhibited an interesting antifeedant activity. A preliminary study showed that this oil presented high toxicity against this insect.
