Effetti dell'attività antropica sulla flora spontanea delle coste benacensi.

1996

Viene presentato uno studio floristico effettuato tra il '92 ed il '94 lungo la sponda bresciana del lago di Garda, su una fascia compresa tra 0 e 100 m sul livello del lago. Tra le entità censite sono state distinte cinque diverse florule rappresentative dei diversi ambienti e tipi vegetazionali presenti nell'area studiata. La comparazione tra lo spettro biologico ed i gruppi corologici dell'elenco floristico generale e quelli di ciascuna florula, evidenzia differenze significative tra gli ambienti a confronto, che, nella stessa area, sono sottoposti a gradi di antropizzazione diversa: oltre a favorire l'insediamento di una ricca flora alloctona, l'azione antropica ha modificatol'equilibri…

Considerazioni tassonomiche e cariologiche sulle popolazioni siciliane di Sternbergia colchiciflora Waldst. & Kit. (Amaryllidaceae)

2004

A citotaxonomic study on two Sicilian populations of Sternbergia colchiciflora from Madonie and Mt. Etna was carried out. They show marked differences in their morphology and caryology.This suggests to treat them as two distinct taxa, but their correct taxonomic position needs further investigation on other populations of Sternbergia colchiciflora from Mediterranean area

Recent and new taxonomic acquisitions in some native genera of Asteraceae from southern Italy and Sicily

2021

After a brief review of the recent acquisition in some native genera of family Asteraceae from southern Italy and Sicily, a new endemic species of Anthemis (sect. Hiorthia) is described from Sicily and named Anthemis parlatoreana. The locus classicus of the new taxon, falling in the NW Tyrrhenian coast of the island (Castellammare del Golfo, Trapani), coincides with that of Ptilostemon greuteri, another endemic very rare species of the Sicilian flora. Data on the morphology, distribution, ecology and conservation status of the new species are provided. The taxonomic relationships with the other Sicilian taxa of the same section, in particular A. cupaniana, are also analyzed. The simultaneou…

Mapping quantitative trait loci affecting biochemical and morphological fruit properties in eggplant (Solanum melongena L.)

2016

Eggplant berries are a source of health-promoting metabolites including antioxidant and nutraceutical compounds, mainly anthocyanins and chlorogenic acid; however, they also contain some anti-nutritional compounds such as steroidal glycoalkaloids (SGA) and saponins, which are responsible for the bitter taste of the flesh and with potential toxic effects on humans. Up to now, Quantitative Trait Loci (QTL) for the metabolic content are far from being characterized in eggplant, thus hampering the application of breeding programs aimed at improving its fruit quality. Here we report on the identification of some QTL for the fruit metabolic content in an F2 intraspecific mapping population of 156…

Phytochemical profile and antioxidative properties of Plinia trunciflora fruits: A new source of nutraceuticals.

2020

Abstract This study evaluated the polyphenol profile and the antioxidative properties of Plinia trunciflora (O. Berg) Kausel fruits. Folin-Ciocalteau and pH-jumping methods indicated that these berries are a major source of antioxidant polyphenols (1201.05 mg GAE/100 g FW), particularly anthocyanins. HPLC-DAD-ESI-MS/MS analysis identified cyanidine glycosides as the main components. Flavon-3-ols and hydrolysable-tannins were also found. CAA assay showed that extracts of P. trunciflora fruits prevent lipid peroxidation in HepG2 cells with higher efficacy than other colourful fruits (CAA50 935.25 mg FW/mL cell medium). Moreover, our results suggested that the observed antioxidant protection i…

Increased Stress Resistance and Lifespan in Chaenorhabditis elegans Wildtype and Knockout Mutants—Implications for Depression Treatment by Medicinal …

2021

Depression and anxiety disorders are widespread diseases, and they belong to the leading causes of disability and greatest burdens on healthcare systems worldwide. It is expected that the numbers will dramatically rise during the COVID-19 pandemic. Established medications are not sufficient to adequately treat depression and are not available for everyone. Plants from traditional medicine may be promising alternatives to treat depressive symptoms. The model organism Chaenorhabditis elegans was used to assess the stress reducing effects of methanol/dichlormethane extracts from plants used in traditional medicine. After initial screening for antioxidant activity, nine extracts were selected f…
