Chemical composition and antimicrobial activity of volatile components from capitula and aerial parts of Rhaponticum acaule DC growing wild in Tunisia

In the present study, the volatile compounds of essential oil of Foeniculum vulgare (fennel), Salvia officinalis (sage), Vitis vinifera (grape), Lavandula angustifolia (lavender) were analysed by gas chromatography-mass spectrometry (GC-MS) using the Nist and Willey libraries. It was determined that the main components of Foeniculum sp. were anethole (41.11%), carvacrol (9.18%). whereas main components of Salvia sp were 1.8 cineole (34.09%), caryophyllene (10.95%), camphor (9.44%), α-pinene (8.42%). Vitis sp. contained linoleic acid (36.98%), 2,4-decadienal (30.79%). Finally, volatile component of Lavandula sp. was linalool (33.57%), linalyl acetate (30.74%). Photoxic antibacterial activity of volatile oil of those plants against Escherichia coli (ATCC 25293), Klebsiella pneumoniae (10031), Salmonella thyphimurium, Bacillus subtilis (ATCC 6633), Staphylococcus aureus (ATCC 25925), Enterococcus feacalis (ATCC 29212) were examined by using disc diffusion method. We demonstrated that volatile oil effectively can be activated by a standard LED light. In vitro, significant phototoxicity was demonstrated by volatile oil of Foeniculum sp. and Vitis sp. (P < 0.05), while minor phototoxicity was induced by Lavandula sp. Therefore, volatile oil of plant can be considered as a potential photosensitizer in the photochemical therapy.

“…No inhibitory effect was observed for P. notatum and R. stolonifer. The minimum inhibitory concentration (MIC) ( Table 3) varied with organism: 25 mg/ml for S. aureus and E. coli, 50 mg/ml for B. substilis, S. typhi and C. albicans and 100 mg/ml for P. aeruginosa, K. pneumoniae and A. niger and are comparable to essential oils of other origins [28,41,42]. These results indicate that the essential oil of the plant M. alternifolius possesses antibacterial activity.…”

The chemical composition was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The constituents were identified by their mass spectra and Kovats' indices. Fivety (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were : 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α-pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). The antioxidant activity of the oils was assessed by measurement of metal chelating activity, the reductive potential, the free radical scavenging (DPPH) assay. The antioxidant activity was compared with that of synthetic antioxidants: butylated hydroxyanisole (BHT) , and the essential oils . The results showed as the Essential oil of M vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Listeria monocytogene, Pseudomonas aeruginosa , Agrobacterium tumefaciens and Salmonella enterica.
