NUNZIATINA DE TOMMASI

E' stato separato cromatograficamente l'essudato di Salvia miniata Fernald, specie messicana i cui estratti totali avevano dimostrato attività erbicida contro Papaver rhoeas L.e Avena sativa L. in test preliminari. Alcuni diterpeni isolati da questa specie hanno dimostrato attività fitotossica antigerminativa e attività inibente la crescita...

Among the marine sponges, the genera Ircinia and Sarcotragus are the major source of polyprenylated compounds, both benzoquinones and benzohydroquinones [1, 2]. Biological studies conducted on hydroxylated 2-octaprenylhydroquinones have shown antioxidant activity [3], antifouling activity against Balanus amphitrite Darwin cyprids [4], and...

The iconography of medicinal and aromatic plant in art masterpieces can be an interesting contribution to the ethnobotanical knowledge related to the historic period when the artefact was produced. Along herbarium specimens, sometimes misrepresenting the morphological characters, the images inside artistic expressions not meant for scientific...

The antimicrobial activity of the surface exudate obtained by rinsing the aerial parts of S. buchananii Hedge (Lamiaceae) [1] with CH2Cl2 was preliminary evaluated by testing 10 μl of 2-fold dilutions (ranging from 1000 mg/L to 64 mg/L) on selected multi-drug-resistant Gram-positive strains, appropriately seeded on agar plates [2]. A clear halo...

The Salvia rosmarinus "Eretto Liguria" ecotype was studied as a source of valuable bioactive compounds. LC-MS analysis of the methanolic extract underlined the presence of diterpenoids, triterpenoids, polyphenolic acids, and flavonoids. The anti-virulence activity of carnosic acid along with the other most abundant compounds against...

Salvia corrugata Vahl. is an interesting source of abietane and abeo-abietane compounds that showed antibacterial, antitumor, and cytotoxic activities. The aim of the study was to obtain transformed roots of S. corrugata and to evaluate the production of terpenoids in comparison with in vivo root production. Hairy roots were initiated from leaf...

During our research on plant compounds from Salvia species able to face the constantly increasing resistance to antibiotics (1), the antimicrobial properties of the dichloromethane extract obtained from the surface of the aerial parts of S. tingitana were investigated following a bioassay-oriented fractionation approach. The surface extract...

Quorum‐sensing (QS) is a regulatory mechanism in bacterial communication, important for pathogenesis control. The search for small molecules active as quorum‐sensing inhibitors (QSI) that can synergize with antibiotics is considered a good strategy to counteract the problem of antibiotic resistance. Here the antimicrobial labdane diterpenoids...

: The Italian garlic ecotype "Vessalico" possesses distinct characteristics compared to its French parent cultivars Messidor and Messidrôme, used for sowing, as well as other ecotypes in neighboring regions. However, due to the lack of a standardized seed supply method and cultivation protocol among farmers in the Vessalico area, a need to...

In this study the Italian garlic "Aglio di Vessalico" was compared with the French cultivars Messidrôme and Messidor, whose cloves are used every year by the growers of Vessalico (Imperia, Italy) for sowing, and with the geographically adjacent "Aglio di Caraglio". UHPLC-Q-trap analyses of the extracts of these commercial garlic accessions...

Introduction: The development of agriculture in terms of sustainability and low environmental impact is, at present, a great challenge, mainly in underdeveloped and marginal geographical areas. The Salvia rosmarinus "Eretto Liguria" ecotype is widespread in Liguria (Northwest Italy), and farmers commonly use it by for cuttings and for...

Salvia rosmarinus (L.) Spenn. 1 is a Mediterranean aromatic shrub widely cultivated for its aromatic, medicinal and ornamental uses. The species is growing in a large diversity of habitats and from sea level up to 1500 meters 2. Salvia rosmarinus "Eretto Liguria" ecotype is widespread in Northwest Italy, and it is commonly used by farmers for...

A targeted NMR metabolomic approach was used to characterise Salvia rosmarinus "Eretto Liguria" ecotype, commonly used in Northwest Italy by farmers for cuttings and for marketing, with a view to application and registration processes for designation of protected geographical indications. Quali- quantitative NMR based investigation was perfomed...
