The essential oils of flowers and remaining parts of the plant Senecio gallicus (Asteraceae), growing wild in Sfax (Tunisia), were obtained by hydrodistillation over a period of two years (2012 and 2013). Their analysis by Gas Chromatography-Mass Spectrometry (GC-MS), led to a total number of 36 components, belonging to different classes of chemical compounds. Oils compositions were characterized by the abundance of monoterpenes hydrocarbons, the major compounds present in flowers for the two years of study were  respectively the sabinene (49.45% and 28.86%), the α-pinene (9.67% and 9.1%), and the β-myrcene (9.88% and 10.97%). These compounds were also dominant in the essential oils of the plant without flowers where they represent (65.34% and 55%) for the sabinene, (4.14% and 7.3%) for α-pinene, and (6.86% and 0%) for β-myrcene. Obtained essential oils were tested for many biological activities and showed a moderate effect against the fungus Trichoderma reesei and bacteria such as Bacillus sp and Staphylococcus aureus. This study of the Senecio gallicus essential oils represents the first one in Tunisia.

Antibacterial Effect of Clove Leaf Extract (Syzygium aromaticum) against Escherichia coli and Staphylococcus aureus Escherichia coli and Staphylococcus aureus are microorganisms that cause infection. Overcoming infection using antibiotics is known to generate bacteria that are resistant to some antibiotics, hence the need of other antibacterial resources. One of the natural sources that can be utilized is clove leaf (Syzygium aromaticum). This study aims to determine the types of compounds contained in clove leaves and their inhibitory activity against E. coli and S. aureus. The study began with extraction using maceration techniques, then the separation of the compounds through ethanol, n-hexane, and ethyl acetate fractionation. Next step was the identification of secondary metabolites of clove leaf compounds using Gas Chromatography-Mass Spectrometry (GC-MS). The results showed the ethyl acetate fraction was the most active in inhibiting the growth of E. coli and S. aureus with a minimum inhibitory value (MIC) of 10%. The most dominant compound in the ethyl acetate fraction was found to be caffeine with a content of 23.36%.  Keywords: antibacterial, clove leaves, GC-MS, MIC, Syzygium aromaticum ABSTRAK Escherichia coli dan Staphylococcus aureus adalah mikroorganisme penyebab infeksi. Penanggulangan infeksi menggunakan antibiotik telah memunculkan bakteri yang resisten terhadap beberapa antibiotik sehingga perlu mencari sumber antibakteri lain. Salah satu bahan alam yang dapat dimanfaatkan adalah daun cengkeh (Syzygium aromaticum). Penelitian ini bertujuan mengetahui jenis senyawa yang terkandung dalam daun cengkeh dan aktivitas penghambatannya terhadap bakteri E. coli dan S. aureus. Penelitian diawali dengan ekstraksi menggunakan teknik maserasi, kemudian dilakukan pemisahan senyawa berdasarkan tingkat kepolaran melalui fraksinasi etanol, n-heksan, dan etil asetat. Hasil fraksinasi diujikan ke bakteri uji. Identifikasi senyawa metabolit sekunder daun cengkeh menggunakan Gas Chromatography Mass Spectrometry (GC-MS). Hasil penelitian menunjukkan bahwa fraksi etil asetat paling aktif menghambat pertumbuhan bakteri E. coli dan S. aureus dengan nilai kadar hambat minimum (KHM) 10%. Senyawa paling dominan pada fraksi etil asetat adalah kafein dengan kadar 23,36%.

The aim of this study was to determine the chemical variability of wormwood extracts as affected by the growing region. Antioxidant and antimicrobial activities were also investigated. The essential oil composition variability ofA. absinthiumL. aerial parts collected from four different Tunisian regions was assessed by gas chromatography (GC/FID) and by gas chromatography mass spectrometry (GC/MS). In addition, total polyphenols, flavonoids, and condensed tannins as well as antioxidant, antibacterial, and antifungal activities of methanolic extract and essential oils were undertaken. Chromatographic analysis of wormwood essential oils showed the predominance of monoterpene hydrocarbons represented mainly by chamazulene. RP-HPLC analysis of wormwood methanolic extract revealed the predominance of phenolic acids. Antiradical activity was region-dependant and the methanolic extract of Bou Salem region has the strongest activity (CI50=9.38±0.82 µg/mL). Concerning the reducing power, the methanolic extract of Bou Salem, Jérissa, and Boukornine regions was more active than the positive control. Obtained results of antimicrobial activities showed that wormwood essential oil is endowed with important antibacterial activity which was strongly related to the organoleptic quality of oil which appeared strongly region-dependant.A. absinthiumL. EOs investigated are quite interesting from a pharmaceutical standpoint because of their biological activities.

Total Oil

Essential oils isolated from needles of Pinus patula by hydrodistillation were analyzed by gas chromatography-flame ionization detection (GC-FID) and gas chromatography mass spectrometry (GC-MS). Thirty-eight compounds were identified, representing 98.3% of the total oil. The oil was rich in monoterpene hydrocarbons (62.4%), particularly α-pinene (35.2%) and β-phellandrene (19.5%). The in vitro antifungal assay showed that P. patula oil significantly inhibited the growth of 9 plant pathogenic fungi. The oil, when tested on Sinapis arvensis, Lolium rigidum, Phalaris canariensis and Trifolium campestre, completely inhibited seed germination and seedling growth of all species. Our preliminary results showed that P. patula essential oil could be valorized for the control of weeds and fungal plant diseases.
