Chemical composition, antioxidant and antibacterial activities of the essential oils of medicinal plant Ammodaucus leucotrichus from Algeria

Medicinal uses, phytochemistry and pharmacology of Ammodaucus leucotrichus

“…In addition, reports on the isolation, and identification of individual chemical constituents have revealed the presence of perillaldehyde and limonene as major compounds. The new guainolide lactone, ammolactone and new monoterpenoid 3-hydroxyperiilaldehyde, methylperillate, borneolangelate and γ-decalactone were also found in this species [2,17]. The presence of such metabolites indicates the importance of plant extracts, for examples terpenes are considered as suitable penetration enhancers in pharmaceutical industries [18], alkaloids are considered to be the primary active ingredients in plant-derived medicines [19], flavonoids are considered important due to their antioxidant, anti-inflammatory, antimicrobial, anticancer, anti-HIV, anticoagulant, immunomodulatory, antitubercular and anti-allergic activities [20], Perillaldehyde, the major compound in Ammodaucus leucotrichus extracts, has the potential to conserve the quality and safety of foods and fresh produce.…”

“…The value of the essential oil of seeds showed a better antioxidant activity than that shown by Ascorbic acid. In another experiment, Dahmane et al [17] assessed antioxidant activities of essential oils obtained from the fruits of Ammodaucus leucotrichus using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay and the β-carotene bleaching assay. Essential oils of Ammodaucus leucotrichus exhibited weak antioxidant abilities to reduce DPPH radicals.…”

“…When compared to BHT and ascorbic acid, oils have been found significantly less effective than these antioxidant agents (p < 0.05). However, essential oils exhibited significantly lower inhibition against linoleic acid oxidation and weak antioxidant abilities for reduce DPPH radicals [17]. Sebaa et al [5] evaluated antioxidant activities of oils essential, aqueous, and methanol extracts of fruits of Ammodaucus leucotrichus using the reducing power method and the DPPH method.…”

“…Dahmane et al [17] evaluated antibacterial activities of the essential oil acquired from the fruits of Ammodaucus leucotrichus using disc diffusion and agar dilution methods against nine bacterial strains, 5 Gram positive and 4 Gram negative. The essential oils exerted a broad antibacterial spectrum with diameter of inhibition zones ranging from 9.66 to 52.66 mm, while it was 10.66-39.00 mm for the positive control.…”

“…The essential oil obtained from the seeds of Ammodaucus leucotrichus showed significant antibacterial activity against Micrococcus luteus while moderately active against Klebsiella pneumonia, Staphylococcus 86 Germacrene D Seed, fruit [16,17] 87 Β -Selinene Seed [16] 88 Globulol Seed, aerial part [16,24] aureus and Bacillus subtilis. The hydro-distilled oil it was inactive against Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi [16].…”
