Antioxidant activity and fatty acids quantification in Sicilian purslane germplasm

2019

Portulaca oleracea is an annual succulent herb in the family Portulacaceae. It is a nutritious vegetable with high antioxidant properties and, it is among the richest plant source of ω-3 fatty acids, as well as a rich source of ω-6 fatty acids, ascorbic acid, tocopherols and beta-carotene. In the present study, three purslane populations under different Mediterranean environmental conditions for two years, for future valorization as novel food sources of omega-3 fatty acids, were evaluated. In particular, biomorphological characteristics, total phenols and fatty acids content were determined. The antioxidant activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl assay. The population…

Typification and taxonomic status of Portulaca macrantha (Portulacaceae)

2010

The name Portulaca macrantha (Maire) Ricceri & Arrigoni and its basionym, P. oleracea var. macrantha Maire, from Morocco, are lectotypified. Seed micromorphology demonstrates that the species is distinct from the closely related P. papillatostellulata and P. rausii. It does not occur in Italy.

Control of Portulaca oleracea by boldo and lemon essential oils in different soils

2015

Soil characteristics influence plant growth and can affect the phytotoxicity of the essential oils. In this study chemical composition and herbicidal activity of Peumus boldus Mol. and lemon essential oils in different growing medium against Portulaca oleracea L. was investigated. Ninety-four compounds accounting between 95.5 and 99.8% of the total essential oil were identified by gas chromatography-mass spectrometry in boldo and lemon essential oils. Ascaridole (31.56. ±. 0.15%), p-cymene (21.58. ±. 0.09%) and 1,8-cineole (12.57. ±. 0.13%) were the main compounds in P. boldus whereas large amount of limonene (59.28%) followed of β-pinene (12.96%) and γ-terpinene (10.92%) were found in lemo…
