Phytochemical characterization and antioxidant activity of the aerial part extracts from two species of Matthiola wild in Sicily: Matthiola sinuata a…

2022

As part of a project aimed at investigating the specific and intraspecific taxa of Matthiola which grow spontaneously in Sicily (Italy), in this work our research has been focused on Matthiola tricuspidata and Matthiola sinuata. The phenolic and volatile compounds of the hydroalcoholic extracts from the aerial parts of the selected species have been characterized by HPLC-PDA/ESI-MS and SPME-GC/MS analyses. Moreover, the antioxidant capacity in vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power and Fe2+ chelating activity assays) and the toxicity (Artemia salina lethality bioassay) of the extracts were investigated. The phytochemical analyses highlighted quite different phenolic and…

First record of Carex vesicaria (Cyperaceae) in Sicily.

2004

The first record of Carex vesicaria from Sicily is reported. This circumboreal species, so far known from the peninsular regions of Italy and from Corsica, has been found in a marshy mead- ow within the Fagus sylvatica and Acer pseudoplatanus woody belt of the Nebrodi mountains (N-E Sicily). The phytocoenosis established in this locality is characterized by C. vesicaria itself together with a few other hygrophytes such as Galium elongatum, Mentha aquatica and Juncus effusus. This plant community belongs to a context of hygro-hydrophilous vegetation where marshy features characterized by Juncus striatus and Calliergonella cuspidata alternate with the lacustrine ones characterized by Potamoge…

Segnalazioni floristiche e vegetazionali per le zone umide costiere del territorio di Petrosino (Sicilia occidentale)

2017

Si riportano popolazioni inedite di alcune specie di angiosperme rare per il territorio siciliano, localizzate nelle aree umide costiere del territorio di Petrosino (provincia di Trapani), attualmente tutelate come sito della rete europea “Natura 2000” (codice ITA010006), e come zona “Ramsar”: si tratta nel dettaglio di Apium graveolens, Briza minor, Carex extensa, Cladium mariscus, Euphorbia hirsuta, Ipomoea sagittata, Ruppia drepanensis, Sonchus maritimus. Per ogni specie viene brevemente illustrata l’importanza dei nuovi reperti nel contesto regionale. Viene inoltre segnalata la presenza di un habitat prioritario non censito nel piano di gestione del sito Natura 2000, ossia “7210*: Palud…

Avance sobre la flora medicinal en la Sierra de Mariola (Valencia-Alicante)

2004

Se han estudiado las diferentes especies medicinales que presentan mayor popularidad en la Sierra de Mariola (Alicante-Valencia, España). Se han identificado un total de 67 especies botánicas en 9 entrevistas realizadas, encontrándose una clara dominancia de las especies pertenecientes a las familias Labiatae y Compositae. The most well-known medicinal species from Sierra Mariola (Alicante-Valencia, Spain) were studied. After nine interviews, 67 botanical species were identified, most of them belonging to Labiatae and Compositae.

A new species of Smyrnium (Apiaceae) related to S. perfoliatum

2015

On the basis of plant collections recently carried out in Sicily as well as the study of the herbarium material kept in PAL and PAL-Gr, a new species of Smyrnium (Apiaceae) is described here. This new taxon, named Smyrnium dimartinoi, is related to S. perfoliatum and is presently known from Sicily, Crete and realistically elsewhere in the Mediterranean. In such range it occurs in open woods and clearings of the Mediterranean-temperate and submontane belt.

Studies on the response of soil microflora to the application of the fungicide fenhexamid

2007

The aim of this work was to evaluate the impact of the fungicide fenhexamid (FEX) on the genetic structure of soil bacterial communities using the Ribosomal Intergenic Spacer Analysis molecular technique. Using real-time PCR, we also tried to quantify the pcaH sequences which encode the dioxygenases involved in the degradation process of a variety of aromatic compounds. Soil taken from a vineyard in the Etna Park (Sicily, Italy) was treated with FEX in the ratio 2 µg g-1 soil every 7 days, the process being repeated four times. The analyses were carried out before treatment and 7 days after each further application of FEX. At the same time, the degradation rate was evaluated. The use of FEX…

Towards a checklist of the Italian gypsophilous vascular flora.

2016

The strict relationship between plants and particular types of substrate has long been known to botanists and plant ecologists who have dealt with this issue. The peculiar flora growing on Italian gypsum substrates has been underlined since the nineteenth century (1, 2, 3). The concept of plant gypsophily can be defined as the exclusiveness or marked preference for living on gypsum outcropping rocks. Thus, only those plant species which show preference, or even exclusivity, for gypsum substrates, should be classified as gypsophilous (4). The main aim of this research has been to provide a checklist of the Italian gypsophilous flora. The study was made possible through international collabor…
