Daucus carota subsp. maximus (Desf.) Ball from Pantelleria, Sicily (Italy): isolation of essential oils and evaluation of their bioactivity
2021
Daucus is a genus of economically important plants belonging to Apiaceae family spread in temperate regions. Species of this genus are used as food and several biological properties have reported. The chemical composition of the essential oils from different organs (roots, stems and flowers) of Daucus carota subsp. maximus, a species not previously investigated, was analyzed by GC-MS. Our results showed the presence of β-phellandrene as the most abundant component of stems and flowers and of γ-terpinene as a major compound of the oil from the roots. Flower essential oil caused a greater increase in the activity of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) i…
Antimicrobial, Antibiofilm, and Antioxidant Properties of Essential Oil of Foeniculum vulgare Mill. Leaves
2022
Foeniculum vulgare (Apiaceae) is an aromatic fennel with important practices in medicinal and traditional fields, used in the treatment of digestive complications, and gastrointestinal and respiratory disorders. Its leaves and stems, tender and fresh, are used in the production of pasta dressing and main courses, while its seeds, with a strong smell of anise, are excellent flavoring for baked goods, meat dishes, fish, and alcoholic beverages. The aim of this work is concerning the extraction of essential oil (EO) from the leaves of F. vulgare subsp. vulgare var. vulgare, investigating antimicrobial, antibiofilm, and antioxidant efficacy. In particular, GC-MS analysis showed how the chemical…
The chemical composition of the aerial parts of Stachys spreitzenhoferi (Lamiaceae) growing in Kythira Island (Greece), and their antioxidant, antimi…
2022
The Stachys L. genus has been used in traditional medicine to treat skin inflammations, stomach disorders, and stress. The aim of this study was to investigate the chemical profile and biological activity of the methanolic extract of Stachys spreitzenhoferi Heldr. (Lamiaceae) aerial parts, collected on the island of Kythira, South Greece. The analysis by liquid chromatography coupled with electrospray ionization and high-resolution mass spectrometry [LC-(-)ESI/HRMSn] of the methanol extract revealed the occurrence of thirty-six compounds - flavonoids, phenylethanoid glycosides, iridoids, quinic acid derivatives, aliphatic alcohol glycosides, and oligosaccharides - highlighting the substanti…
Chemical composition, antimicrobial and antioxidant activities of the essential oil of Italian Prangos trifida (Mill.) Herrnst. & Heyn
2022
In this work, the essential oil of the aerial parts of a not previously investigated accession of Prangos trifida (Mill.) Herrnst. & Heyn (Apiaceae), collected in Northern Italy, was analysed by GC/MS. Twenty-five compounds were identified, accounting for 91.30% of the total oil, which is characterised by a high content of monoterpene hydrocarbons (71.26%). The main constituents of the essential oil were cis-beta-ocimene (18.12%), alpha-phellandrene (12.14%), sylvestrene (11.32%), p-mentha-1,3,8-triene (9.56%) and alpha-pinene (8.85%). The essential oil of P. trifida showed a good antimicrobial activity directed above all against Gram-positive bacteria, and had an interesting antioxidan…
