Selected AbstractsESSENTIAL OIL COMPOSITION OF SALVIA VERBENACA L. GROWING WILD IN TUNISIAJOURNAL OF FOOD BIOCHEMISTRY, Issue 1 2010MOUNA BEN TAARIT ABSTRACT The essential oil of aerial parts of Salvia verbenaca L., collected in three different locations in Tunisia, were obtained by hydrodistillation and analyzed by gas chromatography (GC) and GC,mass spectrometry. The oil yields of dried plants (w/w) were 0.09, 0.10 and 0.12% in Sabelet Ben Ammar, Sers and Somaa, respectively. Seventy-seven compounds were identified. The monoterpene hydrocarbons and oxygenated sesquiterpenes had the highest contributions. The major constituents in Sabelet Ben Ammar were viridiflorol (21.8%), camphene (17.6%), methyl eugenol (9.4%) and ,-caryophyllene (7.1%), while those of essential oil collected from Somaa, were tricyclene (18.8%), nonane (10.3%), methyl eugenol (7.7%) and terpinolene (7.3%). In samples collected from Sers, essential oil consists mainly of (Z)-,-ocimene (29.5%), ,-phellandrene (8.2%), ,-thujone (7.9%) and ,-pinene (5.5%). PRACTICAL APPLICATIONS In this study, it has been found that the oils of wild-growing Salvia verbenaca L. in Tunisia are rich in oxygenated sesquiterpenes and monoterpene hydrocarbons with great economical values. The plant family Labiatae contains several species with potential therapeutic activity due to their essential oils. Pharmacology, pharmaceutical botany, medical and clinical microbiology, phytopathology and food preservation are some fields in which essential oils can be applied. Many Salvia spp. are used as herbal tea and for food flavoring, as well as in cosmetics, perfumery and the pharmaceutical industry. It has shown that essential oil of S. verbenaca have strong antibacterial, antioxidant, antifungal, anti-inflammatory activities and peripheral analgesic properties.

There are over three hundred species of native or naturalised plants found growing wild in Wakehurst Place. Certain areas away from the formal beds have been left wild, but are managed for the encouragement of wild flowers and a visitor taking a gentle stroll around the gardens will have no difficulty in finding many of them.

Fifty-eight components were identified, with sabinene (32.4%) and terpinen-4-ol (13.7%) as the main constituents. The essential oil was tested against 11 bacteria using the agar disc diffusion method, and exhibited a significant antibacterial activity against Salmonella enterica, Staphylococcus epidermidis, Staphylococcus aureus and Bacillus cereus (MICs = 2,4 µl/ml).

The essential oil of A. kopetdaghensis was isolated by hydrodistillation in 2.14% (v/w) yield. The chemical composition of the essential oil was examined by GC and GC,MS. Thirty-three compounds were identified, representing 86.8% of the total oil. The major constituents were methyleugenol (24.4%), geranial (13.6%), davanone (11.1%), camphor (9.8%) and neral (7.4%). Minimum inhibitory concentration was determined, using the agar dilution method, against eight bacteria and two fungal strains. The essential oil showed a moderate antimicrobial activity.

DCFLAVOUR AND FRAGRANCE JOURNAL, Issue 2 2006Hassan Norouzi-Arasi Abstract The volatile oil from the aerial parts of Acroptilon repens (L.) DC. (Russian knapweed) growing wild in Iran was investigated by GC and GC,MS. Twenty-two components, representing 84.0% of the oil, were identified. The main constituents of the oil were caryophyllene oxide (36.6%), , -copaene (15.6%), , -caryophylene (10.0%) and , -copaene-4- , -ol (5.0%). In addition, the oil was assayed against six Gram-positive and Gram-negative bacteria by measuring the growth inhibitory zone. The oil of A. repens inhibited the growth of Gram-positive bacteria. Staphylococcus saprophyticus and Staphylococcus epidermidis showed strong inhibition zones, while Staphylococcus aureus showed a lower inhibition. The Gram-negative bacteria were insensitive to the oil. Copyright © 2005 John Wiley & Sons, Ltd.

Salehi Abstract The chemical composition of the essential oil of Salvia palaestina Benth. growing wild in Iran, was examined by GC and GC,MS. 60 components, representing 91.7% of the total oil, were characterized. The main components were germacrene D (14.0%), , -bisabolene (11.9%), 1- epi -cubenol (9.8%), decanal (7.0%), , -caryophyllene (6.1%) and isobornyl butanoate (5.8%).

Shawl Abstract The aerial parts from the flowering plants of Achillea millefolium L., on hydrodistillation gave 0.014% (v/w) of an oil on fresh weight basis. GC and GC,MS analysis of the oil resulted in the identification of 86 constituents, representing 97% of the oil. Camphor (28%), 1,8-cineole (12%), germacrene-D (12%) and cis -chrysanthenyl acetate (8%) were the major components. Further comparison of our results with those mentioned in the literature suggests that A. millefolium oils vary greatly along the species range. Copyright © 2002 John Wiley & Sons, Ltd.

The major components found in the oils of specimens B, collected at São Sebastião da Boa Vista, State of Par a, were 1,8-cineole (23.9%), borneol (21.8%) and ,-caryophyllene (18.8%). The oils of specimens C and D, collected at Melgaço, Marajó Island, State of Pará, were dominated by ,-pinene (51.1%; 14.5%), 1,8-cineole (16.5%; 36.7%), limonene (15.0%; ,) and ,-pinene (10.3%; 7.9%), respectively.
