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 ...201121902563
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 ...201020981614
survey of human pathogenic actinomycetes and fungi in soil from rome and other italian part of a study sponsored by the ministry of health of italy, a research program on pathogenic actinomycetes, keratinophilic and pathogenic fungi in soil was carried out. two hundred soil samples, collected from different areas of the city of rome, calabria, emilia romagna, latium, apulia, sardinia, sicily, tuscany and umbria, were examined by several techniques to detect the widest possible variety of pathogenic actinomycetes and fungi. seven isolates of nocardia asteroides, four of actinoma ...19817012635
