Phytochemical Profile and Antioxidant Activity of the Aerial Part Extracts from Matthiola incana subsp. rupestris and subsp. pulchella (Brassicaceae)…

2021

As part of a project aimed at investigating the Matthiola taxa endemic to Sicily (Italy), this study focused on Matthiola incana, an edible species used in the traditional medicine of various countries. Herein, the characterization of phenolic and volatile compounds, the antioxidant capacity in vitro (1,1-diphenyl-2-picrylhydrazil (DPPH), reducing power and Fe2+ chelating activity assays) and the toxicity test (Artemia salina lethality bioassay) of the hydroalcoholic extracts from the aerial parts of M. incana subsp. rupestris from Mt. Pellegrino (Palermo) and Mt. Erice (Trapani), and of M. incana subsp. pulchella are reported. The results are compared with those previously shown for M. inc…

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…
