essential oil composition and internal transcribed spacer its sequence variability of four south croatian Satureja species lamiaceae
Molecules, 2009Co-Authors: Nada Bezic, Ivica Samanic, Valerija Dunkic, Visnja Besendorfer, Jasna PuizinaAbstract:The purpose of this study was to compare the essential oil profiles of four South-Croatian Satureja species, as determined by GC/FID and GC/MS, with their DNA sequences for an internal transcribed spacer (ITS1-5.8S-ITS2) of the nuclear ribosomal DNA. A phylogenetic analysis showed that S. montana and S. cuneifolia, characterized by a similar essential oil composition, rich in the monoterpene hydrocarbon carvacrol, clustered together with high and moderate bootstrap support. On the contrary, S. subspicata and S. visianii, characterized by quite unique essential oil compositions, clustered together with the moderate bootstrap support. All four Croatian Satureja species clustered in one clade, separately from Macaronesian S. hortensis,although it had essential oil composition similar to that of S. montana and S. cuneifolia. This is the first report on the comparison between the phytochemical and DNA sequence data in Satureja species and useful contribution to the better understanding of interspecies relationships in this genus.

phytochemical analysis and in vitro antimicrobial activity of two Satureja species essential oils
Phytotherapy Research, 2004Co-Authors: Mirjana Skocibusic, Nada BezicAbstract:The phytochemical GC[sol ]MS analysis and in vitro antimicrobial activity of the essential oils of the aerial parts of Satureja montana L. and Satureja cuneifolia Ten., collected in Croatia were performed. The major compound of S. montana oil was the phenolic monoterpene carvacrol (45.7%). Other important compounds were the monoterpenic hydrocarbons p-cymene (12.6%), γ-terpinene (8.1%) and the oxygen-containing compounds carvacrol methyl ether, borneol, thymol and thymol methyl ether. The volatile oil of S. cuneifolia was characterized as β-cubebene (8.7%), limonene (8.3%), α-pinene (6.9%), spathulenol and β-caryophyllene. The antimicrobial effects of S. montana and S. cuneifolia oils were found to have a broad spectrum activity against multidrug-resistant pathogens by the broth microdilution method. These oils were active against all the test strains, with the exception of Pseudomonas aeruginosa. Compared with S. cuneifolia, savory oil exhibited greater antimicrobial activity. The maximum activity of savory oil was observed against Escherichia coli, methicillin-resistant Staphylococcus aureus and against the yeast (Candida albicans). The essential oil of S. cuneifolia was also found to inhibit the growth of medically important pathogens such as S. aureus and E. coli. Fungicidal activity for both oils against C. albicans and S. cerevisiae was also observed. Copyright © 2004 John Wiley & Sons, Ltd.

Characterization of the essential oil volatiles of Satureja thymbra and Satureja parnassica: influence of harvesting time and antimicrobial activity.
Journal of agricultural and food chemistry, 2006Co-Authors: Nikos Chorianopoulos, Epameinondas Evergetis, Athanasios Mallouchos, Eleftherios Kalpoutzakis, George-john E. Nychas, Serkos A. HaroutounianAbstract:Seasonal variation in chemical composition of essential oils obtained from Satureja parnassica subsp. parnassica Heldr. & Sart ex Boiss. and Satureja thymbra L. was determined by GC and GC-MS analysis. The in vitro antibacterial activities of these essential oils were evaluated at two different initial levels against two common foodborne bacteria. Their minimum inhibitory concentration (MIC) and noninhibitory concentration (NIC) values were determined via an innovative automated technique, which was applied on a Malthus apparatus combining the conductance measurements with the common dilution method. The essential oil concentration fluctuated greatly during the period examined and established that the Satureja oils obtained during the flowering period were the most potent, exhibiting the lowest MIC values and retaining remarkable bactericidal properties. Thus, they represent an inexpensive source of natural antibacterial substances that exhibit potential for use in food systems to prevent the growth of foodborne bacteria and to extend the shelf life of the processed food.

Phytochemical composition and antimicrobial activity of Satureja montana L. and Satureja cuneifolia Ten. essential oils
Acta Botanica Croatica, 2005Co-Authors: Nada Bezić, Mirjana Skočibušić, Valerija DunkićAbstract:The phytochemical composition and the antibacterial activity of the essential oils obtained from the aerial parts of two Lamiaceae species, winter savory (Satureja montana L.) and wild savory (Satureja cuneifolia Ten.) were evaluated. Gas chromatography-mass spectrometry (GC-MS) analysis of the isolated oils resulted in the identification of twenty compounds in the oil of S. montana representing 97% of the total oil and 25 compounds of S. cuneifolia, representing 80% of the total oil. Carvacrol was the major constituent of the S. montana oil (45.7%). Other important compounds were the monoterpenic hydrocarbons p-cymene, -terpinene and the oxygenated compounds carvacrol methyl ether, borneol and thymol. Conversely, the oil of S. cuneifolia contained a low percentage of carvacrol and thymol. The major constituents of wild savory oil were sesquiterpenes -cubebene (8.7%), spathulenol, -caryophyllene, followed by the monoterpenic hydrocarbons limonene and -pinene. The screening of the antimicrobial activities of essential oils were individually evalated against nine microorganisms, using a disc diffusion metod. The oil of S. montana exhibited greater antimicrobial activity than the oil of wild savory. Maximum activity of winter savory oil was observed against Escherichia coli, the methicillin-resistant Staphylococcus aureus and against yeast (Candida albicans). The essential oil of S. cuneifolia was also found to inhibit the growth of pathogens such as S. aureus and E. coli. A fungicidal activity against C. albicans and Saccharomyces cerevisiae was also found in both oils.

Localities and seasonal variations in the chemical composition of essential oils of Satureja montana L. and S. cuneifolia Ten
Flavour and Fragrance Journal, 2001Co-Authors: Mladen Miloš, Nada Bezić, Ani Radonić, Valerija DunkićAbstract:The essential oils of Satureja montana L. and Satureja cuneifolia Ten. were subjected to detailed GC–MS analysis in order to determine possible similarities between them and also the differences in their chemical compositions, depending on the locality and the stage of development. The plant materials were collected prior to, during and after flowering from three different locations in the central part of Dalmatia (Croatia). For both plants the qualitative composition of the components appeared to be constant in three phenological stages and in three different localities. However, considerable differences were found to exist in the amounts of several compounds. Copyright © 2001 John Wiley & Sons, Ltd.
