| chemical characterization and biological activity of essential oils from daucus carota l. subsp. carota growing wild on the mediterranean coast and on the atlantic coast. | the essential oils and supercritical co(2) extracts of wild daucus carota l. subsp. carota growing spontaneously in sardinia and in portugal were investigated. the main components in the sardinian essential oil of flowering and mature umbels with seeds are beta-bisabolene (17.6-51.0%) and 11-alpha-(h)-himachal-4-en-1-beta-ol (9.0-21.6%); instead, the oils from portuguese samples are predominantly composed of geranyl acetate (5.2-65.0%) and alpha-pinene (3.5-37.9%). supercritical extracts contain ... | 2009 | 18950693 |
| chemical composition and biological assays of essential oils of calamintha nepeta (l.) savi subsp. nepeta (lamiaceae). | aerial parts of wild calamintha nepeta (l.) savi subsp. nepeta growing spontaneously on the mediterranean coast (sardinia island, italy) and on the atlantic coast (portugal) were used as a matrix for the supercritical extraction of volatile oil with co(2). the collected extracts were analysed by gc-fid and gc-ms methods and their compositions were compared with that of the essential oil isolated by hydrodistillation, but the differences were not relevant. a strong chemical variability was observ ... | 2010 | 20981614 |
| Antifungal activity and chemical composition of essential oils from Smyrnium olusatrum L. (Apiaceae) from Italy and Portugal. | The essential oils and supercritical CO(2) extracts of wild Smyrnium olusatrum L. growing in Sardinia (Italy) and in Portugal were investigated. For the study, oils were isolated from total plant aerial part (umbels containing seeds). The content of ß-phellandrene (67.3% vs. 42.7%) and a-pinene (31.9% vs. 1.2%), respectively, the main components of Portuguese and Italian essential oils, declined during the maturation stage of the umbels. Contrarily, some other important components, particularly ... | 2011 | 21902563 |
| antifungal activity of extracts from cynomorium coccineum growing wild in sardinia island (italy). | cynomorium coccineum l. is a non-photosynthetic plant, spread over mediterranean countries, amply used in traditional medicine. the aim of this study was to evaluate for the first time the antifungal activity of its extracts. the antifungal activity was evaluated using the macrodilution method against candida spp., cryptococcus neoformans and dermatophyte strains. the methanolic extract was very active against c. neoformans, candida guilliermondii and candida krusei, with minimal inhibitory conc ... | 2015 | 25598435 |
| chemical characterisation and biological activity of leaf essential oils obtained from pistacia terebinthus growing wild in tunisia and sardinia island. | in the present work the chemical compositions, measured by gc and gc-ms, of the essential oils obtained by hydrodistillation from leaves of pistacia terebinthus collected in bizerte (tunisia) and baunei (italy) are reported. both essential oils possessed high content of monoterpene hydrocarbons (86.3% and 90.9%, respectively), being α-pinene (62.4 vs. 35.0)%, camphene (3.0 vs. 2.4)%, β-pinene (12.1 vs. 4.5)%, terpinolene (1.7 vs. 35.2)% and β-phellandrene (3.8 vs. 4.5)% the main components. the ... | 2017 | 28278668 |
| genetic and pathological characteristics of cryptococcus gattii and cryptococcus neoformans var. neoformans from meningoencephalitis in autochthonous goats and mouflons, sardinia, italy. | in this study, we examined in sardinia the brain of 555 autochthonous sheep, 50 goats, and 4 mouflons which were found affected by neurological signs. we found 6 goats and one mouflon with meningoencephalitis caused by cryptococcus sp. there was no evidence of cryptococcal infections in any of the examined sheep. mlst genotyping on cryptococcus sp. isolates identified cryptococcus gatti genotype aflp4/vgi and cryptococcus neoformans var. neoformans genotype aflp2/vniv. phylogenetically, all cryp ... | 2015 | 25840469 |
