Chemical composition and antibacterial activities of Capparis spinosa essential oils from Algeria

Abstract

Abstract. Benachour H, Ramdani M, Lograda T, Chalard P, Figueredo J. 2020. Chemical composition and antibacterial activities of Capparis spinosa essential oils from Algeria. Biodiversitas 21: 161-169. The essential oils of Capparis spinosa L. collected from six locations in Algeria were obtained by hydro-distillation. The chemical composition of oils was performed by GC-MS. The disc diffusion method is applied for the antibacterial activity. The extraction produced low yield (0.03%). The result of chromatographic analysis (GC/MS) leads to the identification of 33 components; palmitic acid (38.19%), nonanal-n (12.61%), cymene-2,5-dimethoxy-para (8.94%) and octacosane (5.49%) were the major components of these oils. The result of cluster analysis based on essential oils constituents showed the presence of three chemotypes,i.e., the chemotype of Nonanal-n-Cymen 2,5 dimethoxy para-Dodecanal, the chemotype of Nonanal-n-Hexadecanoic acid-tetracosane and the chemotype Tetracosane-n-pentyl furane-2-octacosane. In-vitro antimicrobial activity of caper oils against nine bacterial species showed that the oils have no activity against E. coli and have modest activities against eight other bacterial species tested; however, the desirability test shows that the oils used were not effective on the bacteria tested.

Water Uptake and Germination of Caper (Capparis spinosa L.) Seeds

“…Although it is considered as an underutilized crop, recent studies showed that there is increased interest in the use of the different organs of the plant in medicinal and food technology applications, as they may provide an additional value to their organoleptic properties. Although it is not intended to be an exhaustive list, some of the latest published references for the different parts of the plant are: Flower buds [2,3], leaves [4], fruits [5], aerial parts [6], and roots [7], not forgetting studies on cultivation, particularly irrigation [8].…”

Essential Oil Emulsion from Caper (Capparis spinosa L.) Leaves: Exploration of Its Antibacterial and Antioxidant Properties for Possible Application as a Natural Food Preservative

“…In addition, the EO composition of leaves and flower buds of C. spinosa from Croatia was investigated by Kulisic-Bilusic et al [ 16 ], identifying 10 compounds overall, with methyl isothiocyanate at a level over 90%. A greater number of compounds were instead reported in the EO extracted from the plant’s aerial parts: 29 components were reported by Muhaidat et al [ 19 ] in the EO of C. spinosa aerial parts harvested in the arid bottoms of the Dead Sea valley (Jordan), among which, isopropyl isothiocyanate, methyl isothiocyanate, butyl isothiocyanate, 3-p-menthene, 2-butenyl isothiocyanate, and 3-methylthio-1-hexanol prevailed; later Benachour et al [ 18 ] identified 33 compounds, mainly palmitic acid, nonanal, 2,5-dimethoxy-p-cymene, and octacosane, in the aerial part EO of C. spinosa grown in Algeria.…”

“…On the contrary, the composition and the biological activities of C. spinosa essential oil (EO) have been poorly investigated. Literature data are limited to the composition of leaf EOs from C. spinosa harvested in the Middle East [ 14 , 15 ], the composition and antioxidant activity of EOs obtained from leaves and flower buds and flower buds from Croatia [ 16 ] and Iran [ 17 ], respectively, and the composition and antimicrobial activity of the EO extracted from the aerial parts of C. spinosa harvested in Algeria [ 18 ] and Jordan [ 19 ].…”

The Primary Mode of Action of Lippia graveolens Essential Oil on Salmonella enterica subsp. Enterica Serovar Typhimurium

“…The plant material was collected in January 2019 in the town of Jaruco, located in Jaruco, Mayabeque, Cuba (23 • 04 35.7 N 81 • 57 51.4 W) and was identified as Lippia graveolens (Kunth) by specialists from the "Liliana Dimitrova Horticultural Research Institute". This essence was obtained by hydrodistillation of fresh material for 3 h using Clevenger equipment [20]. The EO of L. graveolens was dried with sodium sulfate (Merck, Madrid, Spain) and a yield of 1.94 ± 0.69 mL was obtained.…”
