The cytotoxic properties of Natural Coumarins Isolated from roots of Ferulago campestris (Apiaceae) and of synthetic ester derivatives aegelinol
2010
Grandivittin (1), agasyllin (2), aegelinol benzoate (3) and felamidin (20), four natural coumarins isolated from Ferulago campestris, and several synthetic ester derivatives of aegelinol (4) were tested against four tumor cell lines. Some of them were shown to be marginally cytotoxic against the A549 lung cancer cell line.
Antibacterial and anticoagulant activities of coumarins isolated from the flowers of Magydaris tomentosa.
2006
The phytochemical investigation of the acetone and methanol extracts of the flowers of Magydaris tomentosa (Desf.) DC afforded six known coumarins as well as (+)-meranzin hydrate (7), not previously reported as a natural product. The antibacterial activity of umbelliprenin (1), osthol (2), imperatorin (3), citropten (4) and (+)-meranzin hydrate (7) was tested against Gram-positive and Gram-negative bacteria. All coumarins (1-7) isolated in this study inhibited growth of all bacterial strains tested (MIC between 16 and 256 microg/mL), the most active being imperatorin (3) (MICs between 32 and 128 microg/mL) and citropten (4) (MICs between 16 and 256 microg/mL). The anticoagulant activity of …
Cultivation Trials of Dill (Anethum graveolens L.) with Different Row Arrangements
2010
Dill (Anethum graveolens L.) is an annual plant from Umbelliferae. Although in cookery also sprouts and tender leaves are used, the drug from Dill is represented by the scented fruits (“seeds”), largely used for flavouring conserved foods and liqueurs, but also by herbal and cosmetic industry. In this work, we present the results of a trial performed in Sicily, putting under comparison four different row arrangements: CR30 (continuous rows 30 cm apart); CR60 (continuous rows 60 cm apart), CR90 (continuous rows 90 cm apart) and TR (twin rows with a distance of 30 cm inside and 60 cm between twin rows). The plant population on the row (12 plants m-1) was constant and according the row distanc…
Historical biogeography in a linear system: genetic variation of Sea Rocket (Cakile maritima) and Sea Holly (Eryngium maritimum) along European coasts
2000
The exclusively coastal Cakile maritima and Eryngium maritimum represent a linear biogeographical system. Genetic variation among 25 individuals of C. maritima and 16 individuals of E. maritimum, from the coasts of Europe, North Africa and the Canary Islands, was analysed using random amplified polymorphic DNAs (RAPDs) and intersimple sequence repeats (ISSRs). Genetic distances (Dice) were calculated and used to investigate the correlation between genetic and geographical distances, to construct Neighbour Joining (NJ) trees, and to compare mean genetic distances between areas within and across species. Genetic distances and geographical distances measured along the coast are well correlated…
Ferula sommieriana (Apiaceae), a new species from Pelagie Islands (Sicily)
2021
Ferula sommieriana, a new species occurring in Lampedusa and Linosa, islands of Pelagie Archipelago in the Sicilian Channel, is described and illustrated. Previously it was attributed to F. communis, from which it differs in several features regarding mainly the morphology and anatomy of terminal leaf lobes and mericarps, as well as the shape and size of reproductive structures. Its ecology, conservation status and relationships with other allied Mediterranean species of the sect. Ferula are provided, as well as the analytical keys of the species belonging to the aforesaid section.
Medicinal Properties of Mediterranean Oyster Mushrooms: Species of Genus Pleurotus (Higher Basidiomycetes)
2017
The term “Mediterranean area,” applied in this chapter, refers to the definition reported in Med-Checklist and particularly to all countries bordering the Mediterranean Sea plus Portugal, Bulgaria, the Crimea (Ukraine), and Jordan. The “Mediterranean oyster mushrooms” is a geographically and ecologically well-defined group of Basidiomycetes. The medicinal properties of some widely investigated species such as Pleurotus ostreatus and P. eryngii are recognized worldwide, while in the case of some other Mediterranean Pleurotus taxa, there is still a lack of knowledge. A substantial increase in knowledge about the anticancer and antibacterial properties of the group of Pleurotus species growing…
A new species of Ferula (Apiaceae) from Malta
2018
Ferula melitensis, a new species from the Malta Archipelago, is described and illustrated. It belongs to the taxonomic group of F. communis, showing close relationships mainly with F. tunetana, F. arrigonii, F. communis s.str. and F. glauca, from which it differs in several features regarding the stem, leaves (mainly for shape and size of terminal segments), flowers and mericarps; other significant differences regard the ecology and phenology. The investigations, carried out on living plants, herbarium material and literature data, regard the morphological analysis of vegetative and reproductive structures, the anatomy of terminal leaf segments and mericarps, as well as the shape and size o…
Essential Oil of Leaves and Fruits ofAthamanta siculaL. (Apiaceae)
2003
Abstract The essential oils obtained separately from the leaves and the fruits of Athamanta sicula L. collected in Sicily were studied by capillary GC/MS. The main component in the leaf oil was myristicin (97.6%), while β-pinene (2.8%), β-phellandrene (5.8%), δ-3-carene (22.6%), terpinolene (20.5%) and myristicin (41.3%) were the main components of the fruit oil.
A new ferulol derivative isolated from the aerial parts of Ferulago nodosa (L.) Boiss. growing in Sicily (Italy)
2022
Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area being present in Crete, Greece, Albania, and probably in Macedonia. Although the western disjointed population of Sicily has been classified as an endemic sub-species, F. nodosa subsp. geniculata (Guss.) Troia & Raimondo, it is not officially accepted. From the aerial parts of the Sicilian accession of this species four known metabolites (1–4), and a new ferulol derivative (5), were isolated and characterized. The structure of the new compounds was determined by mean of extensive NMR spectroscopic experiments.
A new irregular diterpenoid of biogenetic interest from the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae)
2007
A new irregular acyclic diterpene, magytomol acetate (2), has been isolated from the light petroleum extract of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) and its structure has been elucidated by means of extensive spectroscopic experiments. The new compound can be considered the acetyl derivative of the biogenetic precursor of other irregular diterpenes isolated from other species belonging to the family Apiaceae.
